Exploitation Conditions

Exploitation requires an attacker to trick an authenticated WordPress user - in practice an administrator or other privileged operator with a valid session for the target site - into visiting attacker-controlled content, because the AI Engine plugin (through 3.8.8) fails to verify request authenticity for a state-changing action (CWE-352). The limiting factors are substantial: the victim must be actively logged in and must perform the interaction (UI:R), so there is no silent, fully remote unauthenticated path, and success depends on the victim holding sufficient privilege for the forced action to matter. The exact plugin endpoint/feature and the resulting action are not described in the available sources.

Impact

This is a CWE-352 Cross-Site Request Forgery flaw in the Meow Apps AI Engine WordPress plugin (through 3.8.8), reported by Patchstack and assigned CVSS 8.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). The vector shows a network-reachable, low-complexity issue requiring no attacker privileges (PR:N) but mandatory victim interaction (UI:R) - the classic CSRF shape where the attacker holds no credentials and instead rides the session of a logged-in user who is lured into triggering the request. The high C/I/A ratings originate from Patchstack's scoring; the description does not state which plugin action is forced, so the actual impact is asserted by the source rather than demonstrated in the available text. vuln.today assigns a 'this_week' priority, indicating elevated but not emergency urgency. Key real-risk signals are absent: there is no CISA KEV listing, no EPSS probability was provided, and no exploitation status is indicated, so there is no evidence of active exploitation. The practical risk is therefore moderate and conditional - CSRF requires social-engineering a specific authenticated (typically administrator-level) victim into clicking, which bounds mass exploitation, but a popular AI plugin makes it an attractive opportunistic target. Treat the 8.8 as a severity ceiling that depends on landing user interaction, not as evidence of widespread automated attack.

Exploit ScenarioDerived

An attacker crafts a malicious web page or email containing a forged request targeting the AI Engine plugin and lures a logged-in WordPress administrator into visiting it. Because the plugin does not validate request authenticity (missing/weak CSRF token), the victim's browser silently submits the state-changing request under their authenticated session. No public exploit code was identified at time of analysis, and the specific action the forged request performs is not described in the available sources.

AnalysisAIv1 – Oct 30, 2026

Cross-site request forgery in Meow Apps AI Engine, a WordPress plugin, through version 3.8.8 allows unauthenticated remote attackers to induce a logged-in privileged user into executing a state-changing action by visiting attacker-controlled content (CVSS 8.8). The plugin does not verify request authenticity for that action (CWE-352), and successful exploitation requires the victim to be authenticated with sufficient privileges and to interact (UI:R); the exact endpoint and resulting state change are not described in the available sources. No public exploit was identified at time of analysis, and the available data does not list this CVE in CISA KEV.

RemediationAI

No vendor-released patch version is specified in the provided data; consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/ai-engine/vulnerability/wordpress-ai-engine-plugin-3-8-8-cross-site-request-forgery-csrf-vulnerability?_s_id=cve to confirm the fixed release and update AI Engine beyond 3.8.8. The supplied sources document no workaround and list no exact fixed version to cite. If the plugin cannot be updated immediately, disabling AI Engine removes the affected state-changing functionality but also removes the plugin's AI features; confirm the vendor's current guidance before relying on any other mitigation.

Technical ContextAI · show details

The affected component is the AI Engine WordPress plugin by Meow Apps, identified by CPE cpe:2.3:a:meow_apps:ai_engine:*:*:*:*:*:*:*:* and described as affected through 3.8.8. CWE-352 (cross-site request forgery) occurs when a state-changing request is accepted based on the victim's ambient session without a per-request authenticity check; in WordPress deployments this generally means a missing or ineffective nonce/CSRF token and, depending on the action, a missing capability check. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H indicates a network-reachable flaw that does not require attacker authentication but does require victim interaction, with high confidentiality, integrity and availability impact. The specific plugin endpoint, feature and state change are not described in the available sources, so the precise trigger is unverified.

CSRF is network-reachable with no attacker privileges (PR:N) but needs the victim to act (UI:R); impact retained from the source as the forced action is not described, so C/I/A are not independently verifiable.

DescriptionCVE.org

Cross-Site Request Forgery (CSRF) vulnerability in Meow Apps AI Engine ai-engine allows Cross Site Request Forgery.This issue affects AI Engine: from n/a through 3.8.8.

Executive ViewAI

Why It Matters

A high-severity CSRF vulnerability in the popular WordPress plugin AI Engine (versions through 3.8.8) allows unauthenticated attackers to trick privileged users into performing unauthorized actions. This puts any organization using the plugin at risk of configuration changes, data exposure, or privilege escalation, potentially compromising the entire WordPress site and downstream business operations.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Apply WAF rules, enforce strict origin checks, restrict privileged user interactions, and consider plugin removal.
