A malicious WebSocket server can stream many small or empty continuation frames that each pass per-frame and cumulative-size validation, collectively causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of service. Affected applications are those using the undici WebSocket client (new WebSocket(...)) or the WebSocketStream API that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint. All releases starting at undici 6.17.0 are affected. Patches Upgrade to undici v6.27.0, v7.28.0 or v8.5.0. Workarounds No workaround is available. The fix must be applied through an upgrade.

RFC 6265 §5.4 does not specify any decoding and browsers do not decode either. Applications that parse a Set-Cookie header and then forward the parsed value into a response header (proxies, middleware, SSR frameworks) become vulnerable to HTTP response header injection: an attacker-controlled upstream can inject arbitrary Set-Cookie, Location, or Cache-Control headers into the application's downstream response, enabling session fixation, open redirect, or cache poisoning. Affected applications are those that use undici's cookie parsing (parseSetCookie, parseCookie, getSetCookies) and forward the parsed cookie value into a response header. This was introduced in undici 7.0.0 via #3789. Patches Upgrade to undici v6.27.0, v7.28.0 or v8.5.0. Workarounds If upgrade is not immediately possible, do not forward values returned by parseSetCookie/parseCookie/getSetCookies directly into response headers; sanitize the value first to strip or reject CR, LF, NUL, ;, and = bytes.

An attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after a request completes. When the client dispatches the next request on that socket, it associates the injected response with the new request, causing responses to be delivered to the wrong requests. This requires an attacker-controlled or compromised upstream HTTP/1.1 server and keep-alive connection reuse. Patches Upgrade to undici v6.27.0, v7.28.0 or v8.5.0.

Non-spec values are silently mapped to one of the three standard tokens: SameSite=NoneOfYourBusiness is parsed as None, the most permissive setting. SameSite=StrictLax is parsed as Lax, a downgrade from Strict. Affected applications are those that consume Set-Cookie headers from server responses (for example via undici's fetch or proxy code paths) and then forward or rely on the parsed sameSite attribute. A malicious or non-compliant server can coerce the consumer's view of a cookie's SameSite policy to a weaker value, silently degrading the SameSite enforcement the cookie is supposed to provide. This was introduced in undici 5.15.0 when the cookies feature was added. Patches Upgrade to undici v6.27.0, v7.28.0 or v8.5.0. Workarounds After parsing a Set-Cookie header, validate that the resulting sameSite attribute is one of 'Strict', 'Lax', or 'None' (exact, case-insensitive) before forwarding or relying on it.

Details The public verify options include certificateOIDs and the documentation says those OID/value pairs “must be present in the certificate’s extension list.” The policy-construction path used by sigstore.verify() and createVerifier() only copies the SAN and issuer settings into the verification policy and completely ignores certificateOIDs. As a result, callers can believe they are constraining verification to certificates carrying specific Fulcio or workload-identifying OIDs, while the actual verifier never receives those constraints. Any bundle that satisfies the remaining checks is accepted even if the required OID extensions are absent or mismatched. This is reachable from supported usage through the documented certificateOIDs verify option. PoC const { createVerificationPolicy } = require("sigstore/dist/config"); const policy = createVerificationPolicy({ certificateIssuer: "https://issuer.example", certificateIdentityEmail: "victim@<!-- -->example.com", certificateOIDs: { "1.2.3.4": "required-value", }, }); console.log("certificateOIDs" in policy, JSON.stringify(policy)); // false {"subjectAlternativeName":"victim@<!-- -->example.com","extensions":{"issuer":"https://issuer.example"}} Impact Applications that rely on certificateOIDs to restrict which certificates may sign artifacts receive no such protection. Unauthorized certificates that should be rejected on extension policy can be accepted as long as they satisfy the remaining verification checks.

An application that (1) passes untrusted input to Address6 and (2) renders the output of these methods, or the thrown error's parseMessage, as HTML (e.g. via innerHTML) is vulnerable to cross-site scripting. A related issue in v6.helpers.spanAll() produced malformed markup but was not exploitable; it is hardened in the same release for consistency. Details Four related issues were identified and fixed together: Address6.group(): zone ID injection. The Address6 constructor stores the raw input (including any IPv6 zone ID) in this.address before zone stripping. group() then passed this.address to helpers.simpleGroup(), which wrapped each :-separated segment in a <span> element without HTML-escaping the content. A zone ID containing HTML markup was embedded verbatim. Address6.link({ prefix, className }): attribute-value injection. link() concatenated user-supplied prefix and className into the href="…" and class="…" attributes without escaping. A caller passing untrusted content through these options could inject event handlers (e.g. onmouseover) and achieve XSS. Address6 constructor: leading-zero IPv4 error path. The leading-zero branch in parse4in6() built AddressError.parseMessage by concatenating the raw address through String.replace(). Because parse4in6() runs before the bad-character check, any characters in the groups preceding the IPv4 suffix flowed into the error's HTML unescaped. Consumers who render parseMessage as HTML (its documented purpose — it already contains <span class="parse-error"> markup) could be XSS'd by a crafted input such as <img src=x onerror=alert(1)>:10.0.01.1. v6.helpers.spanAll(): attribute-value injection (defense in depth). spanAll() embedded each character of its input into a class="digit value-${n} …" attribute without escaping. Because split('') limits n to a single character this was not exploitable in practice, but it produced malformed markup and is fixed for consistency. Affected Versions All versions up to and including 10.1.0. Patched Version 10.1.1. Impact Real-world exposure is believed to be extremely limited. Analysis of all 425 dependent npm packages as well as GitHub code search found zero consumers of group(), link(), or spanAll(): these HTML-emitting surfaces appear to be unused across published npm packages and public repositories. Applications using only the address-parsing and comparison APIs (isValid, correctForm, isInSubnet, bigInt, etc.) are not affected. Consumers who do render the output of group(), link(), spanAll(), or AddressError.parseMessage as HTML against untrusted input should upgrade. PoC const { Address6 } = require('ip-address'); const addr = new Address6('fe80::1%<img src=x onerror=alert(1)>'); document.body.innerHTML = addr.group(); // fires the onerror handler in 10.1.0 Workarounds If users cannot upgrade immediately: Do not pass untrusted input to the Address6 constructor, or Never render the output of group(), link(), or spanAll(), nor the parseMessage field of any thrown AddressError, as HTML; treat these values as text only, or run them through DOMPurify before inserting into the DOM (DOMPurify's default configuration preserves the library's intended <span> wrapping while stripping any injected event handlers), or Validate input with Address6.isValid() and reject anything that contains a zone identifier (a % character) or characters outside [0-9a-fA-F:/] before passing it to the constructor. Lack of separate CVEs Given the evidence that these methods are not used, and given that they are all of the same construction, maintainers do not think it's relevant or useful to create a separate CVE for each library method.

For bundle v0.2, a tlog entry can be inclusionProof-only (no signed inclusionPromise/set), and the inclusion proof path does not cryptographically bind integratedTime. As a result, an attacker who can supply an untrusted bundle can influence time-based verification decisions by choosing integratedTime. impact If a consumer accepts attacker-provided bundle v0.2 inputs and relies on tlog-derived timestamps for certificate validity checks, verification can be influenced by an unauthenticated timestamp value.

This allows payloadType to be mutated after signing without invalidating the signature, breaking the type-binding guarantee that DSSE is designed to provide. In packages/core/src/dsse.ts, the PAE function builds a string containing payloadType and then encodes it with Buffer.from(prefix, 'ascii'). In Node.js, 'ascii' encoding for string-to-Buffer is equivalent to 'latin1', which truncates characters above U+00FF to their low byte. This means for any ASCII character, there exist Unicode characters (at U+01xx, U+02xx, etc.) that produce the identical encoded byte: Original Codepoint Mutant Codepoint Encoded byte t U+0074 Ŵ U+0174 0x74 e U+0065 ť U+0165 0x65 An attacker can substitute every character in payloadType with a Unicode variant whose low byte matches, producing identical PAE bytes and a passing signature verification. Additionally, payloadType.length returns the JavaScript string length (UTF-16 code units) rather than the UTF-8 byte length required by the DSSE spec, though this is only a contributing factor for non-ASCII types. Reproduction const { preAuthEncoding } = require('@<!-- -->sigstore/core/dist/dsse.js'); const payload = Buffer.from('hello world'); const original = preAuthEncoding('text/plain', payload); // U+01xx chars whose low bytes match the original ASCII chars const mutant = preAuthEncoding('\u0174\u0165\u0178\u0174/\u0170\u016c\u0161\u0169\u016e', payload); console.log('PAE bytes equal:', original.equals(mutant)); // true — should be false

Per POSIX pax, a PAX extended header (x) describes the next file entry, not the intermediary extension headers that may sit between the x header and the file it annotates. Because node-tar lets the PAX size override the byte length of an intervening L/K/x header, an attacker can desynchronize node-tar's stream cursor relative to every other mainstream tar implementation (GNU tar, libarchive/bsdtar, Python tarfile, and the now-fixed tar-rs / astral-tokio-tar). The result is a tar parser interpretation differential (CWE-436): a single crafted archive yields a different set of members under node-tar than under the reference tar tools. An attacker can use this to hide a member from one parser while it is visible to another, which defeats security tooling whose scanner and extractor disagree on archive contents (e.g. a malware/secret scanner that lists entries with one library while a downstream step extracts with another). node-tar is one of the most widely deployed JavaScript tar libraries (it backs npm's own package-tarball handling and is a transitive dependency of a very large fraction of the npm ecosystem), so the blast radius for "files that extract differently depending on the tool" is broad. This is the same root cause and fix that was just addressed upstream in the Rust tar ecosystem (tar-rs / astral-tokio-tar); node-tar carries the equivalent defect and has no equivalent guard. Impact CWE-436 Interpretation Conflict / inconsistent tar parsing (the same class as the prior tar "smuggling" advisories GHSA-j5gw-2vrg-8fgx and GHSA-fp55-jw48-c537). A crafted archive can present one logical member list to a tool that lists or scans with node-tar and a different member list to GNU tar / libarchive / Python tarfile (and vice versa). This lets a malicious file be hidden from a scanner that uses a different parser than the eventual extractor, or hidden from node-tar-based inspection while still landing on disk via a system tar. No authentication is required; the only precondition is that a victim parses an attacker-supplied tar with node-tar. Tar archives are routinely fetched from untrusted sources (package registries, user uploads, CI artifacts, container layers). Severity: Medium. Impact is integrity-of-archive-interpretation, not direct RCE; it is a building block for supply-chain / scanner-evasion attacks rather than a standalone code-execution primitive. Vulnerable code (file:line) src/header.ts (compiled to dist/esm/header.js:49 and dist/commonjs/header.js:85 in the published tar@<!-- -->7.5.15): // Header.decode(buf, off, ex, gex) this.size = ex?.size ?? gex?.size ?? decNumber(buf, off + 124, 12) ex is the currently-accumulated PAX local extended header and gex the PAX global header. The size override from ex/gex is applied unconditionally to whatever header is being decoded next — there is no check that the header being decoded is a real file entry rather than an intermediary extension header. src/parse.ts, [CONSUMEHEADER] constructs the next header with the current EX/GEX applied: const header = new Header(chunk, position, this[EX], this[GEX]) and later branches on whether that header is a metadata entry. this[EX] is cleared only in the non-meta (real file) branch: if (entry.meta) { // L / K / x / g metadata entries: this[EX] is left intact here if (entry.size > this.maxMetaEntrySize) { entry.ignore = true this[STATE] = 'ignore' entry.resume() } else if (entry.size > 0) { this[META] = '' entry.on('data', c => (this[META] += c)) this[STATE] = 'meta' } } else { this[EX] = undefined // EX cleared only once a real file entry is reached } When the stream is ordered x (PAX, size=N) -> L (GNU long-name) -> file, the L header is constructed with this[EX] still set, so its size/remain becomes N instead of the L payload's true length. node-tar then consumes N bytes of "metadata" and resumes header parsing at the wrong offset, landing mid-stream. Every other mainstream parser applies the PAX size only to the following file entry, so they stay synchronized. The correct behavior (and the fix shipped upstream in the Rust tar ecosystem) is to not apply PAX size/overrides when the entry being decoded is itself an extension header (L GNU long-name, K GNU long-link, x PAX local, g PAX global). How input reaches the sink tar.list(), tar.extract()/tar.x(), and tar.Parse/tar.Unpack all route every 512-byte header block through Header.decode(...) with the currently-accumulated EX/GEX. Any consumer that parses an attacker-supplied archive — tar.list, tar.extract, or piping into the streaming Parser — reaches the sink. No options need to be enabled; the default code path is affected.

The negative control proves the divergence is caused solely by the PAX size= override being applied to the intermediary L header — when the same archive carries a PAX record without size=, node-tar parses it identically to the reference tools (longname.txt, file_b). Suggested fix When decoding a header, do not apply PAX size (or other PAX overrides) if the header being decoded is itself an extension header. Concretely, in src/parse.ts clear/ignore this[EX] (and this[GEX] for size) when the header's type is ExtendedHeader, GlobalExtendedHeader, NextFileHasLongPath (GNU L), or NextFileHasLongLinkpath (GNU K); equivalently, in Header.decode, gate the ex?.size ?? gex?.size override on the decoded type not being one of those extension types. This mirrors the upstream Rust fix, which guards pax_size with is_gnu_longname || is_gnu_longlink || is_pax_local_extensions || is_pax_global_extensions.
