FIFU Free and Premium: REST nonce bypass and administrator CSRF
The Featured Image from URL (FIFU) WordPress plugin before 6.0.8, Featured Image from URL (FIFU) Premium WordPress plugin before 8.2.8 do not correctly enforce the REST API nonce, disabling the check for the whole request when a crafted URL is used, which could allow attackers to make a logged-in administrator perform any REST API action, such as creating a new administrator account, via a CSRF attack. The authoritative export identifies the fixed release as 6.0.8 for Free and 8.2.8 for Premium.

This CVE was published Oct 01, 2026 and is one of 13 known issues for this plugin.
Update, patch or deactivate.
Update FIFU Free to 6.0.8 or later, or FIFU Premium to 8.2.8 or later, according to the installed edition. Preserve WordPress REST nonce validation for every cookie-authenticated request; do not disable it based on a URL substring.
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.
