# CVE-2023-50252

> 8.3 HIGH · 🧪 PoC

## Beschreibung

php-svg-lib is an SVG file parsing / rendering library. Prior to version 0.5.1, when handling `` tag that references an `` tag, it merges the attributes from the `` tag to the `` tag. The problem pops up especially when the `href` attribute from the `` tag has not been sanitized. This can lead to an unsafe file read that can cause PHAR Deserialization vulnerability in PHP prior to version 8. Version 0.5.1 contains a patch for this issue.
