This PR updates the GitHub security advisory for CVE-2025-69873, which describes a Regular Expression Denial of Service (ReDoS) vulnerability in the ajv JSON schema validator when using the $data option. The update reflects that the fix originally implemented in v8 has been backported to v6, and provides additional references.
Changes:

- Removed
/E:Pfrom CVSS v4 score for GitHub compatibility - Added references for v6 backport (PR #2588, commit, release tag)
