{"id":"GHSA-h2wf-967x-gxvw","summary":"MantisBT: Stored XSS in print_all_bug_page_word.php","details":"A missing output encoding call in print_all_bug_page_word.php allows any authenticated user to inject arbitrary HTML into an IMG tag's *alt* attribute via an image attachment with a crafted filename such as `probe.\" onload=\"alert(1)`. \n\nWhen any user views the HTML export page (print_all_bug_page_word.php?type_page=html&export=1), the rendered IMG tag becomes `\u003cimg src=\"...\" alt=\"\" onload=\"alert(1)\" /\u003e`, breaking out of the alt attribute. \n\n### Impact\nCross-site scripting.\n\nImpact is limited by MantisBT's Content Security Policy.\n\n### Patches\n- https://github.com/mantisbt/mantisbt/commit/bdd0e364f62759de272dfd4c89b4f51d27be9daa\n\n### Workarounds\nNone\n\n### Resources\n- https://mantisbt.org/bugs/view.php?id=37234\n\n### Credits\nMantisBT thanks the [Dracosec Research Limited](https://dracosec.tech/) team (Chris Chan, Krecendo Hui, William Lam) for discovering and responsibly reporting the issue.","aliases":["CVE-2026-62944"],"modified":"2026-07-15T19:11:50.363816Z","published":"2026-07-15T18:56:00Z","database_specific":{"cwe_ids":["CWE-79"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-15T18:56:00Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/mantisbt/mantisbt/security/advisories/GHSA-h2wf-967x-gxvw"},{"type":"WEB","url":"https://github.com/mantisbt/mantisbt/commit/bdd0e364f62759de272dfd4c89b4f51d27be9daa"},{"type":"PACKAGE","url":"https://github.com/mantisbt/mantisbt"},{"type":"WEB","url":"https://mantisbt.org/bugs/view.php?id=37234"}],"affected":[{"package":{"name":"mantisbt/mantisbt","ecosystem":"Packagist","purl":"pkg:composer/mantisbt/mantisbt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.28.4"}]}],"versions":["2.10.0","2.10.1","2.11.0","2.11.1","2.12.0","2.12.1","2.12.2","2.13.0","2.13.1","2.13.2","2.14.0","2.15.0","2.15.1","2.16.0","2.16.1","2.17.0","2.17.1","2.17.2","2.18.0","2.18.1","2.19.0","2.19.1","2.20.0","2.20.1","2.21.0","2.21.1","2.21.2","2.21.3","2.22.0","2.22.1","2.22.2","2.23.0","2.23.1","2.24.0","2.24.1","2.24.2","2.24.3","2.24.4","2.24.5","2.25.0","2.25.1","2.25.2","2.25.3","2.25.4","2.25.5","2.25.6","2.25.7","2.25.8","2.26.0","2.26.1","2.26.2","2.26.3","2.26.4","2.27.0","2.27.1","2.27.2","2.27.3","2.28.0","2.28.1","2.28.2","2.28.3","2.3.0","2.3.1","2.3.2","2.3.3","2.4.0","2.4.1","2.4.2","2.5.0","2.5.1","2.5.2","2.6.0","2.7.0","2.7.1","2.8.0","2.8.1","2.9.0","2.9.1"],"database_specific":{"last_known_affected_version_range":"\u003c= 2.28.3","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-h2wf-967x-gxvw/GHSA-h2wf-967x-gxvw.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
