CVE-2026-32727

SciTokens is a reference library for generating and using SciTokens.

Published Mar 31, 2026 · updated Jun 17, 2026 · scitokens scitokens library

SciTokens is a reference library for generating and using SciTokens. Prior to version 1.9.7, the Enforcer is vulnerable to a path traversal attack where an attacker can use dot-dot (..) in the scope claim of a token to escape the intended directory restriction. This occurs because the library normalizes both the authorized path (from the token) and the requested path (from the application) before comparing them using startswith. This issue has been patched in version 1.9.7.
