CVE-2026-32725

SciTokens C++ is a minimal library for creating and using SciTokens from C or C++.

Published Mar 31, 2026 · updated Jul 24, 2026 · scitokens scitokens cpp library

SciTokens C++ is a minimal library for creating and using SciTokens from C or C++. Prior to version 1.4.1, scitokens-cpp is vulnerable to an authorization bypass when processing path-based scopes in tokens. The library normalizes the scope path from the token before authorization and collapses ".." path components instead of rejecting them. As a result, an attacker can use parent-directory traversal in the scope claim to broaden the effective authorization beyond the intended directory. This issue has been patched in version 1.4.1.
