NVD Description

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

When using http.CrossOriginProtection, the AddInsecureBypassPattern method can unexpectedly bypass more requests than intended. CrossOriginProtection then skips validation, but forwards the original request path, which may be served by a different handler without the intended security protections.
