{"id":"CVE-2026-55207","state":"PUBLISHED","title":"Pimcore: Account Takeover via Password Reset URL Injection allows unauthenticated attacker to hijack any admin account with 2FA bypass","description":"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.","publishedAt":"2026-07-09T21:02:02.733Z","updatedAt":"2026-07-10T13:34:28.607Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["pimcore pimcore"],"affected":[{"vendor":"pimcore","product":"pimcore","versions":[{"version":">= 2026.1.0, < 2026.1.6","status":"affected"},{"version":"< 2025.4.6","status":"affected"}]}],"references":["https://github.com/pimcore/pimcore/security/advisories/GHSA-h854-c3m3-mh5v","https://github.com/pimcore/studio-backend-bundle/pull/1882","https://github.com/pimcore/studio-backend-bundle/commit/ea9d329686f5e5aea2eec378d63ac2deb965bb27","https://github.com/pimcore/studio-backend-bundle/releases/tag/v2025.4.6","https://github.com/pimcore/studio-backend-bundle/releases/tag/v2026.1.6"],"weaknesses":["CWE-640"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/55xxx/CVE-2026-55207.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-55207","state":"PUBLISHED","datePublished":"2026-07-09T21:02:02.733Z","dateUpdated":"2026-07-10T13:34:28.607Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-16T16:16:32.627Z"},"containers":{"cna":{"title":"Pimcore: Account Takeover via Password Reset URL Injection allows unauthenticated attacker to hijack any admin account with 2FA bypass","descriptions":[{"lang":"en","value":"Pimcore is an Open Source Data & Experience Management Platform.
