{"id":"CVE-2026-55207","aliases":["GHSA-h854-c3m3-mh5v"],"url":"https://o3.security/vulnerability/CVE-2026-55207","summary":"Pimcore: Account Takeover via Password Reset URL Injection allows unauthenticated attacker to hijack any admin account with 2FA bypass","details":"Pimcore is an Open Source Data & Experience Management Platform. Prior to 2025.4.6 and 2026.1.6, an unauthenticated attacker who knows a valid admin username can take over any Pimcore admin account by sending a password reset request with an attacker-controlled resetPasswordUrl. The server generates a real cryptographic recovery token, appends it to the supplied URL, and emails the link to the victim; when the victim clicks the link, the token is sent to the attacker and can be used with POST /pimcore-studio/api/login/token to authenticate with full admin privileges while bypassing two-factor authentication. This issue is fixed in versions 2025.4.6 and 2026.1.6.","published":"2026-07-09T21:02:02.733Z","modified":"2026-08-12T03:51:28.717794779Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"pimcore/studio-backend-bundle","fixedVersion":"2025.4.6"},{"ecosystem":"Packagist","name":"pimcore/studio-backend-bundle","fixedVersion":"2026.1.6"}],"fix":{"url":"https://github.com/pimcore/studio-backend-bundle/commit/ea9d329686f5e5aea2eec378d63ac2deb965bb27","label":"pimcore/studio-backend-bundle@ea9d329"},"references":[{"type":"WEB","url":"https://github.com/pimcore/studio-backend-bundle/releases/tag/v2025.4.6"},{"type":"WEB","url":"https://github.com/pimcore/studio-backend-bundle/releases/tag/v2026.1.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55207.json"},{"type":"ADVISORY","url":"https://github.com/pimcore/pimcore/security/advisories/GHSA-h854-c3m3-mh5v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55207"},{"type":"FIX","url":"https://github.com/pimcore/studio-backend-bundle/commit/ea9d329686f5e5aea2eec378d63ac2deb965bb27"},{"type":"FIX","url":"https://github.com/pimcore/studio-backend-bundle/pull/1882"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.717794779Z"}}
