Description

ORY Oathkeeper is an Identity & Access Proxy (IAP) and Access Control Decision API that authorizes HTTP requests based on sets of Access Rules. Versions prior to 26.2.0 are vulnerable to an authorization bypass via HTTP path traversal. An attacker can craft a URL containing path traversal sequences (e.g. `/public/../admin/secrets`) that resolves to a protected path after normalization, but is matched against a permissive rule because the raw, un-normalized path is used during rule evaluation. Version 26.2.0 contains a patch.
