Résumé
opa-envoy-plugin has an Authorization Bypass via Double-Slash Path Misinterpretation in input.parsed_path
Description d'origine
La description telle que publiée par la source (souvent en anglais).
opa-envoy-plugun is a plugin to enforce OPA policies with Envoy. Versions prior to 1.13.2-envoy-2 have a vulnerability in how the input.parsed_path field is constructed. HTTP request paths are treated as full URIs when parsed; interpreting leading path segments prefixed with double slashes (//) as authority components, and therefore dropping them from the parsed path. This creates a path interpretation mismatch between authorization policies and backend servers, enabling attackers to bypass access controls by crafting requests where the authorization filter evaluates a different path than the one ultimately served. Version 1.13.2-envoy-2 fixes the issue.
