symfony/web-profiler-bundle is vulnerable to Cross-site Scripting (XSS)
39
Low Risk
This Affects:
symfony/web-profiler-bundleTL;DR
CodeExtension::fileExcerpt() escapes PHP files through syntax highlighting but renders non-PHP file lines without escaping. If attacker-controlled content is written to a file later viewed through a profiler excerpt, it can execute as HTML or JavaScript. Pre-fix development profiler views can expose stored XSS to developers. The fix escapes non-PHP file contents before rendering excerpts.
