Description
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 in path-based scope validation. The enforcer used a simple string-prefix comparison when checking whether a requested resource path was covered by a token's authorized scope path. Because the check did not require a path-segment boundary, a token scoped to one path could incorrectly authorize access to sibling paths that merely started with the same prefix. This issue has been patched in version 1.4.1.
