EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 80% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Mantis Bug Tracker (MantisBT) is an open source issue tracker. From 1.0.0 to 2.28.1, lack of validation of filter_target parameter on return_dynamic_filters.php (normally used as an AJAX in View Issues Page) allows an attacker to inject arbitrary HTML if the target is a TEXTAREA custom field. This vulnerability is fixed in 2.28.2.
