GHSA-v29p-3vj4-vg4f published today, alongside netcode 1.4.5 and yojimbo 1.12.1. SECURITY.md gains an entry for it.

One sentence: a connect token that had already established a session could establish another one once that client disconnected, repeating AEAD nonces under the same keys. Affected netcode 1.4.4 and earlier, fixed in 1.4.5; yojimbo 1.12.0 and earlier through the netcode it vendors, fixed in 1.12.1.

The entry follows the shape of the 1.4.0 entry below it: advisory link and publication date, affected range, what the flaw was, the fix commit and the release that carries it, what a user on an affected version does, and the yojimbo mapping. Documentation only, no code changes.

yojimbo's SECURITY.md gains the matching link in mas-bandwidth/yojimbo#343.
