Description

The Arvow AI SEO Writer WordPress plugin before 1.5.4 does not properly restrict access to one of its REST endpoints, whose only access control can be bypassed by unauthenticated users through type juggling when the Arvow AI SEO Writer WordPress plugin before 1.5.4 has not been configured, allowing them to create arbitrary posts and pages and to disclose author account and taxonomy information.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown Arvow AI SEO Writer — Before 1.5.4
