CVE-2026-62944
MantisBT Cross-Site Scripting
Description
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.
