Technical description

Switcher Client is a JavaScript SDK to work with Switcher API which is cloud-based Feature Flag. Unsanitized input flows into Strategy match operation (EXIST), where it is used to build a regular expression. This may result in a Regular expression Denial of Service attack (reDOS). This issue has been patched in version 3.1.4. As a workaround, avoid using Strategy settings that use REGEX in conjunction with EXIST and NOT_EXIST operations.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
