CVE-2025-31501Network attack vector

Browser script execution via crafted permalink

Published May 28, 2025 · Updated May 28, 2025

Cross-site scripting in Best Practical RT 5.0.0 through 5.0.7 allows remote attackers to inject JavaScript through an RT permalink. The CNA record identifies the permalink as the injection locus but does not disclose the responsible file, function, or failed encoding operation. A viewer must open the crafted link for the script to run in that browser's RT context; Best Practical's release notes assign this identifier to the Asset-name issue instead.
