Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
PMD (Maven package net.sourceforge.pmd:pmd-core) versions before 7.22.0 are affected by stored cross-site scripting in the vbhtml and yahtml report formats, which insert rule violation messages into HTML output without escaping. An attacker who can get PMD to analyze crafted source code, such as a pull request from an external contributor, can get script to run in the browser of anyone who opens the generated report. Upgrade to version 7.22.0 or later. Avoid the vbhtml and yahtml formats until then.
