What is CVE-2026-41907?

The UUID.js library, responsible for creating RFC9562 UUIDs, is susceptible to a buffer overflow vulnerability prior to version 14.0.0. In the affected versions, the v3, v5, and v6 functions can accept external output buffers without properly validating buffer sizes. This can lead to potential silent partial writes into the provided buffers, posing risks to data integrity and application stability. Users are advised to upgrade to version 14.0.0 or later for improved security measures.
