## Overview

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.

## Affected

- `svg-sanitizer >= 0.11.0 < 1.1.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
