This makes it possible for unauthenticated attackers to elevate their privileges to a Dokan 'seller' (vendor) account \u2014 including sites where the Dokan vendor signup is explicitly turned off \u2014 and to be auto-authenticated into that account, which grants publishing capabilities beyond those of a normal customer."}], "lastModified": "2026-10-13T13:30:21.620", "sourceIdentifier": "security@wordfence.com"}
