Prior to 11.11, the user-search publication in server/publications/users.js and the searchUsers method in server/models/users.js pass authenticated user-controlled searchTerm and query values to new RegExp() without escaping regular-expression metacharacters. MongoDB-backed deployments evaluate the resulting patterns with PCRE2, allowing a logged-in user to submit catastrophic-backtracking expressions that consume database CPU and degrade or deny service to other users; searchUsers additionally requires board membership or site-admin status. The FerretDB v1 / RE2 unaffected configuration is not practically affected by catastrophic backtracking. This issue is fixed in version 11.11.","score":6.5,"severity":"medium","published":"2026-10-30T16:29:16.786Z","modified":"2026-10-30T16:29:16.786Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"wekan","name":"wekan","platforms":[],"versions":[{"version":"< 11.11","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-119300"}],"remediation":[],"references":["https://github.com/wekan/wekan/security/advisories/GHSA-9846-cj96-6hv5","https://github.com/wekan/wekan/commit/4ce5cf6e102854d326e1dcacde6cd20614525dec","https://github.com/wekan/wekan/releases/tag/v11.11"],"sources":[{"name":"CVE","id":"CVE-2026-119300","modified":"2026-10-30T16:29:16.786Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-119300"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5}],"sourceAffected":[],"observedAt":"2026-10-30T17:32:35.480Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T14:10:32.801Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-30T18:05:36.099Z","attemptedAt":"2026-10-30T18:05:36.099Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-30T18:05:36.531Z","attemptedAt":"2026-10-30T18:05:36.531Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-30T18:05:35.527Z","attemptedAt":"2026-10-30T18:05:35.527Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-30T18:05:36.102Z","attemptedAt":"2026-10-30T18:05:36.102Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-114193","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-114193","modified":"Oct 30, 2026, 4:29:16 PM","score":6.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T18:05:35.527Z"},{"source":"NVD","id":"CVE-2026-119300","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-119300","modified":"2026-10-30T17:17:18.563","score":6.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","checkedAt":"2026-10-30T18:05:36.099Z"}],"aiSummary":{"text":"Wekan versions prior to 11.11 are vulnerable to ReDoS via unescaped user input in RegExp, allowing a logged-in user to degrade or deny service.
