CVE-2026-121445
darylldoyle svg-sanitizer from 1.0.0 before 1.1.0 contains a regular expression denial of service vulnerability in the image-set pattern of stripRemoteCssTokens
darylldoyle svg-sanitizer from 1.0.0 before 1.1.0 contains a regular expression denial of service vulnerability in the image-set pattern of stripRemoteCssTokens() when removeRemoteReferences is enabled. Attackers can submit SVGs with many unclosed image-set tokens to exhaust CPU, or trigger PCRE limits causing sanitize() to throw a TypeError and leave unsanitized content.
