How to fix
- Fixed in: 4.9.6
Update to version 4.9.6 or later immediately. Until patching is possible, enable a Web Application Firewall or security plugin that blocks XSS attacks, such as Patchstack's mitigation rules.
Technical details
The plugin fails to properly neutralize user input during web page generation, allowing stored XSS injection. The vulnerability requires user interaction (an unauthenticated attacker cannot directly inject; a privileged user must be tricked into performing an action) but once injected, the malicious payload executes for all site visitors. The fix is available in version 4.9.6 and later.
