Product Feed Manager for WooCommerce - Security Vulnerability (CVE-2026-87964)

CVE-2026-87964

The Product Feed Manager for WooCommerce – CTX Feed – Support 220+ Shopping, AI & Social Channels plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 8.0.26. This is due to insufficient sanitization of the `feedConfigCustom2` parameter — only `wp_unslash()` is applied before the value is stored verbatim via `update_option()`, and during feed generation the `Custom2Template::evaluate_return()` method passes the stored `{(return ...)}` template expressions directly to PHP's `eval()` function without any code-level sanitization. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to inject and execute arbitrary PHP code on the server, escalating their privileges beyond what the role normally permits to full remote code execution and site takeover. The `ctxfeed_custom2_eval_enabled` option defaults to `true`, meaning no additional administrator configuration is required for this attack path to be exploitable out of the box.

Potential Impact

Severity is HIGH (CVSS 7.2). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on remote code execution potential.

Primary risk drivers: remote code execution potential

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

AI risk score 74/100 (Elevated, High) with priority P3 Priority. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update Product Feed Manager for WooCommerce to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.

Am I affected by this vulnerability?

You are affected if your site runs Product Feed Manager for WooCommerce.

How do I fix it?

Update Product Feed Manager for WooCommerce to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

What can an attacker actually do?

This is a Remote Code Execution flaw. An attacker who exploits it can run their own code on the server, which is total control of the site.
