Operationally, ranked in the top 3.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-28508 is a cross-site scripting vulnerability in MantisBT versions prior to 2.25.2. The flaw exists in browser_search_plugin.php, where the return parameter is output without proper escaping, allowing an attacker to inject arbitrary code into a hidden input field. The issue is tracked under CWE-79 and carries a CVSS 3.1 score of 6.1.
An unauthenticated remote attacker can exploit the vulnerability by supplying a crafted return parameter that is reflected back into the page. Successful exploitation results in execution of attacker-controlled script in the context of a victim user's browser session, with impacts limited to limited confidentiality and integrity loss under a changed scope.
The referenced project sites at mantisbt.org and SourceForge host the MantisBT distribution; the GitHub entry provides a proof-of-concept demonstrating the injection. The EPSS score has remained steady at its peak value of 0.2903 with no material upward trajectory after disclosure.
