This CVE was published Jun 24, 2026 and is one of 1 known issue for this plugin.
Update, patch or deactivate.
Update Assistio to a release after 1.1.2, or disable and remove it until a fixed version is available.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The Assistio plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the assistio_plugin_delete_assistio_settings() function in versions up to, and including, 1.1.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the plugin's options including the critical 'assistiobot_oauth_settings' option, which disrupts the plugin's integration with the Assistio bot service.
