Summary
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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
