This makes it possible for unauthenticated attackers to elevate their privileges to a Dokan 'seller' (vendor) account — including sites where the Dokan vendor signup is explicitly turned off — and to be auto-authenticated into that account, which grants publishing capabilities beyond those of a normal customer."}],"title":"Blocksy Companion <= 2.1.58 - Unauthenticated Privilege Escalation to 'role' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7757f41d-c1f1-4df1-8048-b1c78a897548?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/blocksy-companion/tags/2.1.58/framework/features/account-auth.php#L241"},{"url":"https://plugins.trac.wordpress.org/browser/blocksy-companion/tags/2.1.58/framework/features/account-auth.php#L181"},{"url":"https://plugins.trac.wordpress.org/browser/blocksy-companion/tags/2.1.58/framework/features/account-auth.php#L24"},{"url":"https://plugins.trac.wordpress.org/changeset/3735192/blocksy-companion/tags/2.1.59/framework/features/account-auth.php?old=3723693&old_path=blocksy-companion%2Ftags%2F2.1.58%2Fframework%2Ffeatures%2Faccount-auth.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","baseScore":9.1,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Sawyer"}],"timeline":[{"time":"2026-10-08T14:35:16.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-09T15:15:10.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-107645","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-11T16:38:17.189524Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-11T16:55:20.206Z"}}]}}
