Prior to 1.0.0, Resolver::processReferences() in src/ElementReference/Resolver.php builds the SVG <use> reference graph with a case-sensitive href attribute predicate before cleanHrefAttributes() normalizes mixed-case names. An attacker can provide xlink:HrEf on nested <use> elements so the graph omits those references, after which the sanitizer converts the attribute to canonical xlink:href and returns the live nesting structure without applying the useNestingLimit protection. A consuming application that renders the sanitized SVG can therefore be exposed to the resource exhaustion that control is designed to prevent. This issue is fixed in version 1.0.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-107381)\n\nAffected packages:\n\n- `enshrined/svg-sanitize <= 0.22.0`\n\nPatched in:\n\n- `enshrined/svg-sanitize 1.0.0`\n\nSource: https://github.com/advisories/GHSA-m9xh-6747-9r6f","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":224419,"id":"CVE-2026-107381","ts":1792331050009,"field":"exploit_available","old":"false","new":"true"}]}
