GHSA-45WJ-JX7R-99H8
Vulnerability from github – Published: 2026-09-13 21:31 – Updated: 2026-09-13 21:31pathe through 2.0.3 unconditionally normalizes backslash characters to forward slashes on all platforms, including POSIX systems where backslash is a valid filename character. This causes join(), resolve(), and normalize() to interpret backslash-separated dot notation sequences as directory traversal, diverging from Node.js path.posix behavior and enabling path traversal attacks that bypass common input validation in server-side applications. NOTE: the Supplier reports that "the behavior is documented, intentional, and identical in spirit to path.win32."
