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"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-03T17:32:25.306244Z","id":"CVE-2026-15988","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-03T17:34:26.270Z"}}]}}
