**Name of the Vulnerable Software and Affected Versions** uBlock Origin versions prior to 1.36.2 nMatrix versions prior to 4.4.9 **Description** The issue allows crafted web sites to cause a denial of service due to unbounded recursion, which can trigger memory consumption and a loss of all blocking functionality. This is possible because the software supports an arbitrary depth of parameter nesting for strict blocking. **Recommendations** For uBlock Origin versions prior to 1.36.2, update to version 1.36.2 or later to resolve the issue. For nMatrix versions prior to 4.4.9, update to version 4.4.9 or later to resolve the issue. As a temporary workaround, consider restricting the depth of parameter nesting for strict blocking to prevent unbounded recursion.
