**Name of the Vulnerable Software and Affected Versions** Switcher Client versions prior to 3.1.4 **Description** The issue arises from unsanitized input flowing into the Strategy match operation, specifically the EXIST operation, where it is used to build a regular expression. This can result in a Regular expression Denial of Service attack. **Recommendations** For versions prior to 3.1.4, as a temporary workaround, consider avoiding the use of Strategy settings that utilize REGEX in conjunction with EXIST and NOT EXIST operations until a patch is applied. Update to version 3.1.4 to resolve the issue.
