Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots: SQL injection

Better Messages (affected: <= 3.0.4). A Subscriber or higher can supply group_id message metadata that reaches a SQL query without adequate parameter binding. This can disclose database information. Exploitation requires BuddyBoss Platform installed with Social Groups disabled and its retained wp_bp_groups table; a site that previously disabled Groups can satisfy that prerequisite. The request endpoint and query function are unspecified.

CWE-89 — Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

This CVE was published Sep 25, 2026 and is one of 19 known issues for this plugin.

What to do

Update, patch or deactivate.

The official author release notes confirm remediation by 3.0.6; this does not establish that every intervening release was affected. The first fixed release is not established. Update the affected edition to 3.0.6 or a later maintained release on its supported branch. Reject unexpected client message metadata, validate group IDs and use parameterized queries; enforce group access separately and disable the affected integration until the update is installed. Official author release notes: https://www.better-messages.com/changelog/.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to generic SQL Injection via 'group_id' Message Meta Parameter in all versions up to, and including, 3.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires the BuddyBoss Platform plugin to be installed with its Social Groups component disabled, a state that persists on any site that has previously toggled the Groups component off since BuddyBoss does not drop the wp_bp_groups table upon deactivation.
