Technical ContextAI · show details

Classified as CWE-918 (Server-Side Request Forgery (SSRF)). Affects Homarr. Homarr is an open-source dashboard. Prior to version 1.54.0, an unauthenticated Server-Side Request Forgery (SSRF) vulnerability allows a remote attacker to force the Homarr server to perform arbitrary outbound HTTP requests. This can be used as an internal network access primitive (e.g., reaching loopback/private ranges) from the Homarr host/container network context. This issue has been patched in version 1.54.0.
