ecosystem impact- 17 npm packages depend on uuid (12 direct, 5 indirect)
Ecosystem-wide dependent count for version 12.0.0.
DescriptionNVD
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.
AnalysisAI
Buffer overwrite vulnerability in uuid JavaScript library versions prior to 14.0.0 enables remote attackers to corrupt memory and potentially disclose sensitive information through out-of-range writes when applications use v3, v5, or v6 UUID generation functions with caller-provided output buffers. The library fails to validate buffer boundaries, allowing partial writes beyond allocated memory regions. …

RemediationAI
Within 24 hours: Inventory all applications and dependencies using uuid library versions prior to 14.0.0 via package managers (npm, yarn, pnpm). Within 7 days: Update uuid library to version 14.0.0 or later across all development, staging, and production environments; verify compatibility through regression testing. …
