Security readout for executives and security teams
Plain-English summary
This is a stored XSS issue in the WordPress add2fav plugin version 1.0 and earlier. An administrator-level user could save script content that later runs in another user’s browser. Business impact is limited but real: account trust, site integrity, and visitor/admin sessions may be affected.
Executive priority
Handle during normal vulnerability remediation unless the plugin is on sensitive or externally managed WordPress sites. Prioritize faster if administrator accounts are weakly controlled, shared, or recently suspected of compromise.
Technical view
CVE-2022-37404 is CWE-79 stored cross-site scripting in Christian Salazar’s add2fav WordPress plugin <= 1.0. CVSS 3.1 is 4.8, with network access, low complexity, high privileges required, user interaction required, changed scope, and low confidentiality/integrity impact.
Likely exposure
Exposure is limited to WordPress sites with the add2fav plugin installed at version 1.0 or earlier. The vulnerability requires authenticated administrator-level access, so risk is highest where admin accounts are shared, weakly protected, or already compromised.
Exploitation context
The supplied sources do not show CISA KEV listing or confirmed active exploitation. Exploitation is constrained by high required privileges and user interaction, but stored XSS can still matter if an attacker has administrative access or abuses compromised admin credentials.
Researcher notes
Evidence is sufficient for affected product, version range, CWE, and CVSS. The provided bundle does not identify a fixed version, patch details, exploit proof, or active exploitation. Avoid claiming broader WordPress impact beyond add2fav <= 1.0.
Mitigation direction
- Inventory WordPress sites for the add2fav plugin and confirm installed versions.
- Check Patchstack and the WordPress plugin page for current vendor remediation guidance.
- Remove or disable the plugin if it is unused or no maintained fix is available.
- Restrict administrator access and require strong authentication for WordPress admin accounts.
Validation and detection
- Confirm whether add2fav is installed on each WordPress site.
- Verify whether any installed version is 1.0 or earlier.
- Review WordPress administrator accounts for unnecessary or shared access.
- Check site security logs for suspicious administrator activity around plugin settings.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
