CVE-2024-11929 is a medium-severity Missing Authorization vulnerability in the Responsive FlipBook Plugin Wordpress WordPress plugin, affecting versions <= 2.5.0. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed January 2025, reported by Tieu Pham Trong Nhan.
Vulnerability Overview
The Responsive FlipBook Plugin Wordpress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the rfbwp_save_settings() functionin all versions up to, and including, 2.5.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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-862: Missing Authorization
Responsive FlipBook Plugin Wordpress <= 2.5.0 carries this weakness at rfbwp_save_settings(), and reaching it 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. No fixed build of this plugin is recorded for Responsive FlipBook Plugin Wordpress yet, so installs running <= 2.5.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
