NVD Description

Note: Versions mentioned in the description apply only to the upstream falcosidekick-ui-fips package and not the falcosidekick-ui-fips package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Echo is a Go web framework. Prior to 4.15.3 and 5.2.0, Echo's router and static file handler disagree on URL path decoding. The router matches routes using the raw encoded path (preserving %2F as-is), while StaticDirectoryHandler unescapes %2F to / before resolving filesystem paths. This allows an attacker to bypass route-level access controls and read static files without authorization. This vulnerability is fixed in 4.15.3 and 5.2.0.
