Description
svg-sanitizer from 0.5.3 before 1.1.0 contains a denial of service vulnerability in Sanitizer::sanitize() that repeatedly rescans the whole input while stripping PHP tags. Unauthenticated attackers can upload SVGs with many overlapping PHP tag openers and closers, forcing quadratic preg_replace passes that exhaust worker CPU for minutes.
