Security readout for executives and security teams
Plain-English summary
This vulnerability can let an attacker trick a logged-in WordPress user into making an unintended change that results in stored cross-site scripting. Stored XSS can persist on the site and affect later visitors or administrators. The source data does not name a fixed version or confirm exploitation in the wild.
Executive priority
Treat as high priority for affected WordPress sites, especially public sites or sites managed by multiple administrators. Prioritize inventory, containment, and vendor guidance because the sources do not identify a confirmed patch.
Technical view
CVE-2025-46512 affects Shamim Hasan Custom Functions Plugin custom-functions through version 1.1. It is listed as CWE-352 CSRF leading to stored XSS, CVSS 3.1 score 7.1, network exploitable with low complexity and required user interaction. Privileges are listed as none for the attacker.
Likely exposure
Exposure is limited to WordPress sites with Custom Functions Plugin custom-functions installed at version 1.1 or earlier. The bundle does not provide install prevalence, vulnerable endpoint details, or a confirmed fixed version.
Exploitation context
CISA KEV is false in the provided bundle, and no cited source confirms active exploitation. The attack model requires user interaction, consistent with CSRF, and could produce persistent script execution if successful.
Researcher notes
The public bundle identifies CSRF to stored XSS but omits endpoint, nonce behavior, role prerequisites, exploit maturity, and remediation version. Avoid assuming a patch exists. Validate exposure through asset inventory and controlled defensive review only.
Mitigation direction
- Inventory WordPress sites for custom-functions version 1.1 or earlier.
- Check Patchstack and vendor guidance for a fixed release or official mitigation.
- Disable or remove the plugin where business impact allows until guidance is available.
- Apply least-privilege administration and avoid browsing untrusted links while logged into WordPress.
Validation and detection
- Confirm whether the Custom Functions Plugin is installed on each WordPress property.
- Record installed plugin version and compare against affected versions through 1.1.
- Review WordPress content and admin areas for unexpected stored script content.
- Check security logs for suspicious plugin configuration changes around administrator sessions.
