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 validate buffer boundaries properly. This allowed out-of-range pointer offsets leading to silent partial writes into caller-provided buffers, classified under CWE-823 (Use of Out-of-range Pointer Offset) and CWE-787 (Out-of-bounds Write). This could potentially corrupt memory or cause unexpected behavior. The issue is resolved in uuidjs version 14.0.0.
Potential Impact
The vulnerability allows silent partial writes beyond the intended buffer boundaries when generating UUIDs with certain versions of the uuidjs library. This could lead to memory corruption or data integrity issues in applications using affected versions. No direct evidence of exploitation in the wild is reported. The high CVSS score reflects the potential for significant impact if exploited.
Mitigation Recommendations
Upgrade to uuidjs version 14.0.0 or later, where this vulnerability is fixed. Since the vendor advisory indicates the issue is resolved in 14.0.0, applying this official fix is the recommended remediation. Patch status is confirmed by the vendor advisory stating the fix is included in version 14.0.0.
