When the HAX site is visited, the client's browser will query the supplied URL.\n\n### Affected Resources\n\n- [Operations.php:868](https://github.com/haxtheweb/haxcms-php/blob/master/system/backend/php/lib/Operations.php#L868)\n- `https://<site>/<user>/system/api/saveNode`\n\n### PoC\n\n1.

The attacker can then conduct a phishing attack by convincing another user to visit their malicious HAX site to harvest credentials.","published":"2025-06-09T21:08:44.391Z","modified":"2026-08-12T03:51:39.304721091Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"},"epss":{"score":0.00324,"percentile":0.24809,"asOf":"2026-08-28"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@haxtheweb/haxcms-nodejs","fixedVersion":"11.0.0"}],"fix":{"url":"https://github.com/haxtheweb/haxcms-nodejs/commit/5368eb9b278ca47cd9a83b8d3e6216375615b8f5","label":"haxtheweb/haxcms-nodejs@5368eb9"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/49xxx/CVE-2025-49139.json"},{"type":"ADVISORY","url":"https://github.com/haxtheweb/issues/security/advisories/GHSA-v3ph-2q5q-cg88"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-49139"},{"type":"FIX","url":"https://github.com/haxtheweb/haxcms-nodejs/commit/5368eb9b278ca47cd9a83b8d3e6216375615b8f5"},{"type":"PACKAGE","url":"https://github.com/haxtheweb/issues"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:39.304721091Z"}}
