Summary

A vulnerability in scitokens-cpp prior to version 1.4.1 allows authorization bypass when processing path-based scopes in tokens. The library normalizes the scope path but collapses '..' components instead of rejecting them, allowing an attacker to broaden authorization beyond the intended directory.

Risk Assessment

An attacker can access resources outside the intended directory, potentially leading to unauthorized data read or write.

Recommendation

Update scitokens-cpp to version 1.4.1 or later.

Original NVD description (English source)

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.
