highcovered by 1 sourcefirst seen 2026-07-15

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.
