Authenticated users can call http::* functions with a hostname resolving to a denied IP, or the IP of a denied hostname, to reach blocked internal services.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/surrealdb/surrealdb/commit/9d9a5b0693e499e0d030cac6b618062ec02cd2bc","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-mhv5-88p6-w4c3","tags":[]},{"url":"https://www.vulncheck.com/advisories/surrealdb-3.1.0-before-3.3.0-ssrf-via-port-specific-deny-net-host-aliasing-bypass","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-mhv5-88p6-w4c3","tags":[]}],"exploitRefs":[{"url":"https://github.com/surrealdb/surrealdb/commit/9d9a5b0693e499e0d030cac6b618062ec02cd2bc","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-mhv5-88p6-w4c3","tags":[]},{"url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-mhv5-88p6-w4c3","tags":[]}],"hasPoc":true,"ai":null}
