inspect dependencies for actionpack

Analyze the terminal output to locate any version of Actionpack in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.2.7.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Actionpack, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

There is a possible XSS vulnerability in Rails / Action Pack. This vulnerability has been assigned the CVE identifier CVE-2022-22577. Versions Affected: >= 5.2.0 Not affected: < 5.2.0 Fixed Versions: 7.0.2.4, 6.1.5.1, 6.0.4.8, 5.2.7.1 ## Impact CSP headers were only sent along with responses that Rails considered as "HTML" responses. This left API requests without CSP headers, which could possibly expose users to XSS attacks. ## Releases The FIXED releases are available at the normal locations. ## Workarounds Set a CSP for your API responses manually.
