This CVE was published Oct 24, 2026 and is one of 19 known issues for this plugin.
Update, patch or deactivate.
Update BP Better Messages to 3.1.4 or later. Validate client-side input and use safe DOM/text operations instead of interpreting untrusted values as executable markup. Avoid untrusted crafted links and restrict the affected functionality until updated.
