This is due to the handle_return_to_admin() function trusting a client-controlled cookie (oclaup_original_admin) to determine which user to authenticate as, without any server-side verification that the cookie value was legitimately set during an admin-initiated user switch. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their privileges to administrator by setting the oclaup_original_admin cookie to an administrator's user ID and triggering the \"Return to Admin\" functionality."}],"title":"Login as User <= 1.0.3 - Authenticated (Subscriber+) Privilege Escalation via 'oclaup_original_admin' Cookie","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c0c74d48-6cfc-4899-bd2c-4a80b1f6e05f?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/one-click-login-as-user/trunk/includes/class-login-handler.php#L45"},{"url":"https://plugins.trac.wordpress.org/browser/one-click-login-as-user/tags/1.0.3/includes/class-login-handler.php#L45"},{"url":"https://plugins.trac.wordpress.org/browser/one-click-login-as-user/tags/1.0.3/includes/class-login-handler.php#L50"},{"url":"https://wordpress.org/plugins/one-click-login-as-user/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-639 Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"HA GIA BAO"}],"timeline":[{"time":"2026-04-14T19:44:50.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-15T13:32:27.091082Z","id":"CVE-2026-5617","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":"2026-04-15T16:13:15.117Z"}}]}}
