Detected one or more JavaScript libraries used by the application that are outdated compared to their latest available versions.

Outdated client-side libraries may contain known bugs, security weaknesses, or deprecated functionality that could be exploited by attackers. Even when no publicly disclosed vulnerabilities are known, using outdated components increases the attack surface and may expose the application to future risks.

Using outdated JavaScript libraries can introduce security and stability risks, including:

• Exposure to known vulnerabilities in older versions
• Increased likelihood of client-side attacks (e.g., XSS gadgets, prototype pollution)
• Compatibility issues with modern browsers or other libraries
• Lack of security patches and vendor support

The severity of this issue depends on the specific library and version in use.

It is recommended to upgrade the affected JavaScript libraries to their latest stable versions.

• Replace outdated versions with the most recent supported release
• Review changelogs for breaking changes before upgrading
• Test the application to ensure compatibility after updates
• Remove unused or unnecessary libraries to reduce attack surface

Where immediate upgrades are not possible, consider mitigating risk by restricting usage of vulnerable components and monitoring for related security advisories.

This finding is based on client-side detection techniques and version comparison against known recent releases. In some cases, version information may be inferred from runtime properties and may not reflect custom builds or patched versions.
