At a glance
CVE-2024-9364 is a medium-severity Missing Authorization vulnerability in the SendGrid for WordPress WordPress plugin, affecting versions <= 1.4. 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. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2024, reported by Nishiv.
Vulnerability Overview
The SendGrid for WordPress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'wp_mailplus_clear_logs' function in all versions up to, and including, 1.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the plugin's log files.
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
SendGrid for WordPress <= 1.4 carries this weakness at wp_mailplus_clear_logs, 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 SendGrid for WordPress yet, so installs running <= 1.4 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.
