Prior to 2.28.2, the mc_issue_update() function in MantisBT allows users having update_bug_threshold access (UPDATER, with default settings) to edit, change view state, and modify time tracking on bugnotes belonging to other users — bypassing the default DEVELOPER (level 55) threshold required by the dedicated mc_issue_note_update() function. This vulnerability is fixed in 2.28.2.","published":"2026-05-28T20:28:20.369Z","modified":"2026-08-07T11:51:05.152124994Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"mantisbt/mantisbt","fixedVersion":"2.28.2"}],"fix":{"url":"https://github.com/mantisbt/mantisbt/commit/6e58fae4f22efdc3987f903c8ba2611de17a9435","label":"mantisbt/mantisbt@6e58fae"},"references":[{"type":"WEB","url":"https://mantisbt.org/bugs/view.php?id=37089"},{"type":"WEB","url":"https://mantisbt.org/bugs/view.php?id=37093"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42070.json"},{"type":"ADVISORY","url":"https://github.com/mantisbt/mantisbt/security/advisories/GHSA-pq86-j2c2-47f6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42070"},{"type":"FIX","url":"https://github.com/mantisbt/mantisbt/commit/6e58fae4f22efdc3987f903c8ba2611de17a9435"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:51:05.152124994Z"}}
