Technical details
Stored cross-site scripting (XSS) vulnerability in the HTML report export functionality (plist-to-html, CodeChecker parse --export html, and CodeChecker cmd diff --output html). The vulnerability occurs because json.dumps does not escape the less-than character when embedding report metadata (message, checker name, file path) into script blocks, allowing a closing script tag to prematurely end the element and inject arbitrary HTML/JavaScript. The vulnerability affects multiple code paths: static exporters, the cmd diff flow via getRunResults, and bugviewer.js which assigns innerHTML without sanitization.
