CVE-2026-41907 High · 7.5 CWE-787 Apr 24, 2026

uuid: Missing buffer bounds check in `v3`/`v5`/`v6` when `buf` is provided

uuid is for the creation of RFC9562 (formerly RFC4122) UUIDs. Prior to 14.0.0, v3, v5, and v6 accept external output buffers but do not reject out-of-range writes (small buf or large offset). This allows silent partial writes into caller-provided buffers. This vulnerability is fixed in 14.0.0.

CVE-2026-41988 Low · 2.5 CWE-670 Apr 23, 2026

Always-Incorrect Control Flow Implementation in Uuidjs Uuid

uuid before 14.0.0 can make unexpected writes when external output buffers are used, and the UUID version is 3, 5, or 6. In particular, UUID version 4, which is very commonly used, is unaffected by this issue.
