{"id":"CVE-2026-23626","aliases":["GHSA-jg2j-2w24-54cg"],"url":"https://o3.security/vulnerability/CVE-2026-23626","summary":"Kimai Vulnerable to Authenticated Server-Side Template Injection (SSTI)","details":"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.","published":"2026-01-18T22:45:35.942Z","modified":"2026-08-12T03:51:24.592781595Z","cvss":{"score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"kimai/kimai","fixedVersion":"2.46.0"}],"fix":{"url":"https://github.com/kimai/kimai/commit/6a86afb5fd79f6c1825060b87c09bd1909c2e86f","label":"kimai/kimai@6a86afb"},"references":[{"type":"WEB","url":"https://github.com/kimai/kimai/releases/tag/2.46.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23626.json"},{"type":"ADVISORY","url":"https://github.com/kimai/kimai/security/advisories/GHSA-jg2j-2w24-54cg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23626"},{"type":"FIX","url":"https://github.com/kimai/kimai/commit/6a86afb5fd79f6c1825060b87c09bd1909c2e86f"},{"type":"FIX","url":"https://github.com/kimai/kimai/pull/5757"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.592781595Z"}}
