What it is

YesWiki before 4.6.7 contains an authorization bypass vulnerability in ApiService::isAuthorized() that allows unauthenticated attackers to call admin-only API routes when public API mode is enabled. Attackers can send requests to endpoints like api/ci/update_config and api/archives to overwrite configuration and list, download, or delete backup archives.
