CVE-2025-55166 Information
Aug 13, 2025

Description
savg-sanitizer is a PHP SVG/XML sanitizer. Prior to version 0.22.0 the sanitization logic in the cleanXlinkHrefs method only searches for lower-case attribute name which allows to by-pass the isHrefSafeValue check. As a result this allows cross-site scripting or linking to external domains. This issue has been patched in version 0.22.0.
