NotificationX: Unauthenticated content disclosure and shortcode execution
Summary
The NotificationX WordPress plugin before 3.3.7 has no capability, authentication or nonce checks on its notification preview function. Any unauthenticated visitor can send crafted preview data on a front-end request to read private, draft, pending and password-protected posts and to execute registered shortcodes. The CNA scores this at CVSS 3.1 6.5 (medium), with confidentiality and integrity impact; VulDB reports an additional availability impact, so the sources conflict.
Affected
- NotificationX WordPress plugin, all versions before 3.3.7 (CNA record; VulDB lists up to 3.3.6)
Fixed in
- Version 3.3.7 (the vendor's release notes do not name this CVE; the link is inferred from CVE records)
Workaround
- No workaround documented in the sources reviewed.
- Interim option: disable the plugin or its preview function until 3.3.7 is installed, if this is operationally possible.
Exploitation
- Not known to be exploited in the wild.
- Public proof of concept: unknown. The WPScan reference carries an exploit tag, which has not been verified.
- Authentication is not required and the attack complexity is low.
Our recommendation
- Identify all WordPress sites with NotificationX installed and check the version.
- Update to NotificationX 3.3.7 or later, starting with internet-facing sites and sites with drafts or private content.
- Review whether sensitive content has been exposed via preview and rotate any secrets stored in posts.
- Keep the plugin current, as the product has a history of unauthenticated flaws.
- Check the WPScan advisory and the WordPress.org changelog for confirmation of the fix.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
