The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
mantisbt/mantisbt
source listed<= 2.28.3
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 ``, 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 team (Chris Chan, Krecendo Hui, William Lam) for discovering and responsibly reporting the issue.

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
- vendor patch
The original advisory lists fixed boundaries 2.28.4 for mantisbt/mantisbt. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
