-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ------------------------------------------------------------------------- Debian Security Advisory DSA-6429-1 [email protected] https://www.debian.org/security/ Aron Xu August 11, 2026 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : caddy CVE ID : CVE-2026-27585 CVE-2026-27587 CVE-2026-27588 CVE-2026-27589 CVE-2026-27590 CVE-2026-45692 CVE-2026-52845 CVE-2026-52846 Multiple security issues were discovered in Caddy, a web server with automatic HTTPS, which may result in the bypass of path- or host-based access controls, the execution of an unintended file by a FastCGI backend, the injection of identity headers trusted by applications running behind Caddy, unauthorised reconfiguration of the server through its admin API, or cross-site scripting. The fix for CVE-2026-52845 follows upstream in dropping every request header whose name contains an underscore, for all servers and without an opt-out. Deployments which pass such headers through Caddy, for instance X_Api_Key or gRPC custom metadata keys containing underscores, need to switch to the hyphenated spelling. For the stable distribution (trixie), these problems have been fixed in version 2.6.2-12+deb13u1. We recommend that you upgrade your caddy packages.
