Description

An exponential ReDoS (Regular Expression Denial of Service) can be triggered in the semver-regex npm package, when an attacker is able to supply arbitrary input to the test() method. Some WordPress plugins and themes use this dependency though that doesn’t necessarily mean the plugin itself is vulnerable to exploitation.
