{"id":"GHSA-v3ph-2q5q-cg88","summary":"@haxtheweb/haxcms-nodejs Iframe Phishing vulnerability","details":"### Summary\n\nIn the HAX site editor, users can create a website block to load another site in an iframe. The application allows users to supply a target URL in the website block. 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://\u003csite\u003e/\u003cuser\u003e/system/api/saveNode`\n\n### PoC\n\n1. Set the URL in an iframe pointing to an attacker-controlled server running Responder\n\n![image](https://github.com/user-attachments/assets/baac23ec-7b1e-49cf-864d-c3550b2c71bf)\n\n2. Once another user visits the site, they are prompted to sign in.\n\n![image](https://github.com/user-attachments/assets/a3a0b75d-e12f-49cf-8669-9686353a92e2)\n\n3. If a user inputs credentials, the username and password hash are outputted in Responder.\n\n![image](https://github.com/user-attachments/assets/428542d3-8cf5-4bfa-b759-e630c3ee6ac3)\n\n### Impact\n\nAn authenticated attacker can create a HAX site with a website block pointing at an attacker-controlled server running Responder or a similar tool. The attacker can then conduct a phishing attack by convincing another user to visit their malicious HAX site to harvest credentials.","aliases":["CVE-2025-49139"],"modified":"2026-09-10T03:50:25.594483857Z","published":"2025-06-09T19:07:21Z","database_specific":{"nvd_published_at":"2025-06-09T21:15:47Z","cwe_ids":["CWE-1021"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-06-09T19:07:21Z"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/haxtheweb/haxcms-nodejs/commit/5368eb9b278ca47cd9a83b8d3e6216375615b8f5"},{"type":"PACKAGE","url":"https://github.com/haxtheweb/issues"}],"affected":[{"package":{"name":"@haxtheweb/haxcms-nodejs","ecosystem":"npm","purl":"pkg:npm/%40haxtheweb/haxcms-nodejs"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"11.0.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/06/GHSA-v3ph-2q5q-cg88/GHSA-v3ph-2q5q-cg88.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
