What is CVE-2026-0746?

CVE-2026-0746 is a security flaw in AI Engine – The Chatbot, AI Framework & MCP for WordPress. The AI Engine plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.3.2 via the 'get_audio' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services, if "Public API" is enabled in the plugin settings, and 'allow_url_fopen' is set to 'On' on the server.

Why this CVE matters

Unpatched network-facing software is the leading initial-access vector in public breach reporting. Treat any CVSS-9 class flaw on an internet-reachable system as urgent, regardless of whether public exploit code has been observed yet.

For deployments of AI Engine – The Chatbot, AI Framework & MCP for WordPress that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.

Am I affected?

You are affected if your installation matches any of these version ranges:

Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.

Open AI Engine – The Chatbot, AI Framework & MCP for WordPress's About dialog or run the vendor-documented version-check command. Compare the result against the affected ranges in the advisory.

How to fix CVE-2026-0746

The fix is to apply the patched build listed in the tigroumeow advisory.

Affected versions confirmed in the CVE record:

Update the affected WordPress plugin / theme


<!-- enrich_agent_2:v1 -->
# Pin to the patched build listed in the [advisory](https://www.wordfence.com/threat-intel/vulnerabilities/id/cbba866d-93dd-4ef5-9670-ab958f61f06e?source=cve).
# WP-CLI on the server.
wp plugin update ai-engine-the-chatbot-ai-framework-mcp-for-wordpress 

# If you cannot patch right now, deactivate the plugin.
wp plugin deactivate ai-engine-the-chatbot-ai-framework-mcp-for-wordpress

# Verify the running plugin version.
wp plugin get ai-engine-the-chatbot-ai-framework-mcp-for-wordpress --field=version

Verify the fix worked


<!-- enrich_agent_2:v1 -->
# 1. Confirm the running version matches the fixed-in version from the advisory.
#    Cross-check against the vendor advisory: https://www.wordfence.com/threat-intel/vulnerabilities/id/cbba866d-93dd-4ef5-9670-ab958f61f06e?source=cve

# 2. Re-scan with your vulnerability scanner. The scanner should no longer flag
#    this CVE on the patched host.
# Example with Nmap NSE:
nmap -sV --script vuln <target-host>

# 3. Inspect the service / kernel logs for crash-loops or rollback events in
#    the first hour after the upgrade.
journalctl -u <service-name> --since "1 hour ago"
dmesg --since "1 hour ago"

If you cannot patch immediately

No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.

How to verify the fix worked

If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for log entries that do not match your normal request patterns, especially repeated requests to the same uncommon endpoint, and any administrative changes you cannot tie back to a known operator.

Frequently asked questions

Is CVE-2026-0746 being exploited in the wild?

Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.

Will a WAF or IDS rule fully mitigate CVE-2026-0746?

No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.

How long should I plan for the upgrade?

Typical vendor-documented upgrade windows for AI Engine – The Chatbot, AI Framework & MCP for WordPress run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
