At a glance
CVE-2025-4431 is a medium-severity Improper Access Control vulnerability in the Featured Image Plus WordPress plugin, affecting versions <= 1.6.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.6.6; sites on affected versions should update now. Disclosed May 2025, reported by Kishan Vyas.
Vulnerability Overview
The Featured Image Plus – Quick & Bulk Edit with Unsplash plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the fip_save_attach_featured function in all versions up to, and including, 1.6.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update featured image of any post.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-284: Improper Access Control
Reaching this weakness in Featured Image Plus <= 1.6.4 takes an account at Subscriber level or above. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.
Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Featured Image Plus the fix is 1.6.6: builds <= 1.6.4 are affected, anything from 1.6.6 onward is not.
Remediation
Update to version 1.6.6, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Featured Image Plus 1.6.6 closes this, and updating the plugin is the step that ends it.
