At a glance
CVE-2025-2779 is a medium-severity Missing Authorization vulnerability in the Insert Headers and Footers Code WordPress plugin, affecting versions <= 1.1.2. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.1.3; sites on affected versions should update now. Disclosed April 2025, reported by kr0d.
Vulnerability Overview
The Insert Headers and Footers Code – HT Script plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_dismiss function in all versions up to, and including, 1.1.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update option values to 1/true on the WordPress site. This can be leveraged to update an option that would create an error on the site and deny access to legitimate users or be used to set some values to true, such as registration.
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. A successful exploit has high impact on integrity.
CWE-862: Missing Authorization
Reaching this weakness in Insert Headers and Footers Code <= 1.1.2 takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Insert Headers and Footers Code the fix is 1.1.3: builds <= 1.1.2 are affected, anything from 1.1.3 onward is not.
Remediation
Update to version 1.1.3, 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: Insert Headers and Footers Code 1.1.3 closes this, and updating the plugin is the step that ends it.
