At a glance
CVE-2024-24850 is a critical-severity Missing Authorization vulnerability in the Quicksand Post Filter jQuery Plugin WordPress plugin, affecting versions <= 3.1.1. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed February 2024, reported by Kévin Mosbahi (Mika).
Vulnerability Overview
The Quicksand Post Filter jQuery Plugin plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'quicksand_admin_ajax' function in versions up to, and including, 3.1.1. This makes it possible for unauthenticated attackers to delete arbitrary site options.
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 privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on integrity, availability.
CWE-862: Missing Authorization
Quicksand Post Filter jQuery Plugin <= 3.1.1 carries this weakness at quicksand_admin_ajax, and reaching it takes a caller who can reach the endpoint. 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 Quicksand Post Filter jQuery Plugin yet, so installs running <= 3.1.1 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.
