Simple:Press - Cross-Site Scripting (XSS) (CVE-2022-4029)

Q: Am I affected by this vulnerability?

You are affected if your site runs Simple:Press. No account is needed to exploit this, so a public site is reachable by anyone.

Q: How do I fix it?

Update Simple:Press to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

Vulnerability CVE-2022-4029 PLUGIN simple-press MEDIUM

The Simple:Press plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'sforum_[md5 hash of the WordPress URL]' cookie value in versions up to, and including, 6.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This would be highly complex to exploit as it would require the attacker to set the cookie a cookie for the targeted user.

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

AI risk score 56/100 (Elevated, High) with priority P3 Priority. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update Simple:Press to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
