This makes it possible for unauthenticated attackers to create new administrator accounts with attacker-supplied credentials via a CSRF-based REST authentication bypass, granted they can trick a site administrator into performing an action such as clicking on a link. This bypass can be combined with WordPress's ?_method=POST method-override support to convert a top-navigation GET request into an authenticated POST to the REST users endpoint, requiring no existing account on the attacker's part."}], "title": "AI Engine <= 3.6.5 - Cross-Site Request Forgery to Privilege Escalation via REQUEST_URI Substring Match", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/45816c45-42bc-4163-b700-a1e913f32c97?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L127"}, {"url": "https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L120"}, {"url": "https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L121"}, {"url": "https://plugins.trac.wordpress.org/browser/ai-engine/tags/3.6.2/labs/mcp-oauth.php#L49"}, {"url": "https://plugins.trac.wordpress.org/changeset?old_path=%2Fai-engine/tags/3.6.5&new_path=%2Fai-engine/tags/3.6.6"}, {"url": "https://plugins.trac.wordpress.org/changeset/3628188/ai-engine/trunk/labs/mcp-oauth.php"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-352 Cross-Site Request Forgery (CSRF)", "cweId": "CWE-352", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "UKO"}], "timeline": [{"time": "2026-07-16T19:42:37.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-31T18:40:58.000Z", "lang": "en", "value": "Disclosed"}]}}}
