Prior to version 0.9.44, YARD's static cache lookup reads a request path before the router's path cleanup runs. When a server is configured with a document root, a traversal path such as `/../yard-cache-secret.html` is joined against that root and can return a readable sibling `.html` file outside the intended static tree. Version 0.9.44 patches the issue."}], "lastModified": "2026-06-23T16:06:25.397", "sourceIdentifier": "security-advisories@github.com"}
