Name of the Vulnerable Software and Affected Versions: is-svg package versions 2.1.0 through 4.2.1

Description: The issue concerns a Regular Expression Denial of Service (ReDoS) vulnerability in the is-svg package for Node.js. If an attacker provides a malicious string, the package will get stuck processing the input for a very long time. This occurs because the package uses a vulnerable regular expression.

Recommendations: For versions 2.1.0 through 4.2.1, consider updating to a version that fixes the ReDoS vulnerability in the regular expression. As a temporary workaround, consider restricting input to prevent malicious strings from being processed.
