An unauthenticated remote attacker can cause the server to contact loopback or private-network HTTP services. This can expose internal service behavior and enable interaction with resources that are not directly reachable by the attacker.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/go-gitea/gitea/pull/36729","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-9574-292w-9wmw","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/36729","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-9574-292w-9wmw","tags":[]}],"hasPoc":true,"ai":null}
