{"id":"CVE-2026-23626","state":"PUBLISHED","title":"Kimai Vulnerable to Authenticated Server-Side Template Injection (SSTI)","description":"Kimai is a web-based multi-user time-tracking application. Prior to version 2.46.0, Kimai's export functionality uses a Twig sandbox with an overly permissive security policy (`DefaultPolicy`) that allows arbitrary method calls on objects available in the template context. An authenticated user with export permissions can deploy a malicious Twig template that extracts sensitive information including environment variables, all user password hashes, serialized session tokens, and CSRF tokens. Version 2.46.0 patches this issue.","publishedAt":"2026-01-18T22:45:35.942Z","updatedAt":"2026-01-20T20:07:08.477Z","severity":{"score":6.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["kimai kimai"],"affected":[{"vendor":"kimai","product":"kimai","versions":[{"version":"< 2.46.0","status":"affected"}]}],"references":["https://github.com/kimai/kimai/security/advisories/GHSA-jg2j-2w24-54cg","https://github.com/kimai/kimai/pull/5757","https://github.com/kimai/kimai/commit/6a86afb5fd79f6c1825060b87c09bd1909c2e86f","https://github.com/kimai/kimai/releases/tag/2.46.0"],"weaknesses":["CWE-1336"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/23xxx/CVE-2026-23626.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-23626","state":"PUBLISHED","datePublished":"2026-01-18T22:45:35.942Z","dateUpdated":"2026-01-20T20:07:08.477Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-01-14T16:08:37.482Z"},"containers":{"cna":{"title":"Kimai Vulnerable to Authenticated Server-Side Template Injection (SSTI)","descriptions":[{"lang":"en","value":"Kimai is a web-based multi-user time-tracking application.
