**Name of the Vulnerable Software and Affected Versions** Node.js versions prior to 12.22.4 Node.js versions prior to 14.17.4 Node.js versions prior to 16.6.0 **Description** The issue is related to a use after free attack in Node.js, where an attacker might exploit memory corruption to change process behavior, potentially leading to access to confidential data, disruption of data integrity, and denial of service. The vulnerability is associated with the http2 module, which could allow an attacker to crash the process or potentially execute code in the system when accessing a host controlled by the attacker. **Recommendations** For versions prior to 12.22.4, update to version 12.22.4 or later. For versions prior to 14.17.4, update to version 14.17.4 or later. For versions prior to 16.6.0, update to version 16.6.0 or later. As a temporary workaround, consider disabling the http2 module until a patch is available. Restrict access to the http2 module to minimize the risk of exploitation.

Name of the Vulnerable Software and Affected Versions: es6-crawler-detect versions prior to 3.1.3 Description: The issue arises from the lack of limitation on the length of user agent strings supplied to regex operators. This can lead to potential problems when processing user agent strings of excessive length. Recommendations: For versions prior to 3.1.3, update to version 3.1.3 or later to resolve the issue. As a temporary workaround, consider implementing custom length checks on user agent strings before passing them to regex operators.
