GHSA-W8FP-G9RH-34JH SciTokens has an Authorization Bypass via Incorrect Scope Path Prefix Checking

Summary The Enforcer incorrectly validates scope paths by using a simple prefix match startswith. This allows a token with access to a specific path e.g., /john to also access sibling paths that start with the same prefix e.g., /johnathan, /johnny, which is an Authorization Bypass.

No More, No Less: Least-Privilege Language Models

Least privilege is a core security principle: grant each request only the minimum access needed to achieve its goal. Deployed language models almost never follow it, instead being exposed through a single API endpoint that serves all users and requests. This gap exists not because least privilege...
