CVE-2024-5458

23
FAUCET Score

CVE-2024-5458 is a medium-severity vulnerability affecting PHP versions 8.1.*, 8.2.*, and 8.3.*, specifically impacting the filter_var function when validating URLs with FILTER_VALIDATE_URL. A logic error causes the function to incorrectly validate malformed username and password components within URLs, potentially leading downstream applications to accept and incorrectly parse invalid URLs. The CVSS score is 5.3 (MEDIUM), indicating a network-based attack with low complexity and a low impact on integrity, but no impact on confidentiality or availability. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting a low immediate threat.
