CVE-2026-41907: CWE-823: Use of Out-of-range Pointer Offset in uuidjs uuid
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.
AI Analysis
Technical Summary
The uuidjs library, used for generating RFC9562-compliant UUIDs, had a vulnerability in versions before 14.0.0 where the v3, v5, and v6 functions accepted external output buffers but did not reject out-of-range writes caused by small buffers or large offsets. This improper validation allows silent partial writes into the caller's buffer, classified under CWE-823 (Use of Out-of-range Pointer Offset) and CWE-787 (Out-of-bounds Write). The vulnerability has a CVSS 4.0 score of 8.1, indicating high severity. The issue is resolved in version 14.0.0 of uuidjs.
Potential Impact
Exploitation of this vulnerability can cause silent partial writes to memory buffers provided by the caller, potentially leading to memory corruption or unexpected behavior in applications using vulnerable versions of uuidjs. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Upgrade uuidjs to version 14.0.0 or later, where this vulnerability is fixed. Patch status is confirmed by the vendor advisory indicating the fix in version 14.0.0. No additional mitigations are specified.
