CVE-2026-117541 PUBLISHED

svg-sanitizer 0.11.0 before 1.1.0 Uncaught LogicException DoS via sanitize()

Assigner: VulnCheck
Reserved: 27.10.2026 Published: 27.10.2026 Updated: 27.10.2026

svg-sanitizer from 0.11.0 before 1.1.0 contains an uncaught exception vulnerability that allows attackers to crash callers by submitting well-formed XML without a top-level svg root. Attackers can supply documents with a non-svg root or nested svg element, causing Sanitizer::sanitize() to throw a LogicException instead of returning false, crashing workers or bypassing upload rejection.
