CVE-2026-62944
MantisBT: Stored XSS in print_all_bug_page_word.php
描述
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)`. When any user views the HTML export page (print_all_bug_page_word.php?type_page=html&export=1), the rendered IMG tag becomes `<img src="..." alt="" onload="alert(1)" />`, breaking out of the alt attribute. ### Impact Cross-site scripting. Impact is limited by MantisBT's Content Security Policy. ### Patches - https://github.com/mantisbt/mantisbt/commit/bdd0e364f62759de272dfd4c89b4f51d27be9daa ### Workarounds None ### Resources - https://mantisbt.org/bugs/view.php?id=37234 ### Credits MantisBT thanks the [Dracosec Research Limited](https://dracosec.tech/) team (Chris Chan, Krecendo Hui, William Lam) for discovering and responsibly reporting the issue.
