CVE-2023-50252 is a critical vulnerability in php-svg-lib (versions prior to 0.5.1) and its dependent product, dompdf, stemming from improper handling of merged attributes in SVG <use> and <image> tags. This flaw allows for an unsafe file read, potentially leading to a PHAR Deserialization vulnerability in PHP versions prior to 8. With a CVSS score of 9.8 (CRITICAL), it presents a severe risk due to its network-based attack vector, low attack complexity, and high potential for confidentiality, integrity, and availability impacts. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high FAUCET Risk Score of 88/100 indicates its inherent danger.
