CVE-2026-45072 records a Medium severity (CVSS 5.4) vulnerability in Symfony: Stored XSS in WebProfiler CodeExtension::fileExcerpt() — Unescaped Non-PHP File Rendering. The current sources do not mark it as known exploited. The current feed maps symfony/symfony (generic), symfony/twig-bridge (generic), symfony/web-profiler-bundle (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.4.24 until 6.4.40, 7.4.12, and 8.0.12, the development profiler file_excerpt Twig filter escapes PHP files through highlight_string() but interpolates lines from non-PHP files directly into <code> elements, allowing stored XSS against a developer who opens an attacker-written file such as var/log/dev.log in the profiler. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.
