CVE-2025-53310

7.1 HIGH

📋 TL;DR

A Cross-Site Request Forgery (CSRF) vulnerability in the HidePost WordPress plugin allows attackers to trick authenticated users into performing unintended actions, which can lead to Reflected Cross-Site Scripting (XSS). This affects all WordPress sites running HidePost versions up to 2.3.8. Attackers can exploit this to inject malicious scripts that execute in victims' browsers.

💻 Affected Systems

Products:
  • HidePost WordPress plugin
Versions: n/a through 2.3.8
Operating Systems: Any OS running WordPress
Default Config Vulnerable: ⚠️ Yes
Notes: Affects all WordPress installations with the vulnerable plugin enabled; no special configuration required.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could perform administrative actions on WordPress sites (like adding malicious users, changing settings, or injecting backdoors) by tricking administrators into clicking malicious links, leading to full site compromise.

🟠

Likely Case

Attackers trick authenticated users into executing actions they didn't intend, potentially modifying content, changing settings, or stealing session cookies via XSS payloads.

🟢

If Mitigated

With proper CSRF tokens and input validation, the vulnerability would be prevented, limiting impact to failed exploitation attempts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires tricking an authenticated user into clicking a malicious link; CSRF vulnerabilities are commonly weaponized due to low complexity.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.3.9 or later

Vendor Advisory: https://patchstack.com/database/wordpress/plugin/hidepost/vulnerability/wordpress-hidepost-plugin-2-3-8-cross-site-request-forgery-csrf-vulnerability?_s_id=cve

Restart Required: No

Instructions:

🔧 Temporary Workarounds

Disable HidePost Plugin

all

Temporarily deactivate the plugin to eliminate the vulnerability until patching is possible.

wp plugin deactivate hidepost

Implement CSRF Protection Headers

linux

Add HTTP headers like SameSite cookies or custom CSRF tokens at the web server level to mitigate CSRF attacks.

# In Apache .htaccess: Header always set X-Frame-Options SAMEORIGIN
# In Nginx config: add_header X-Frame-Options SAMEORIGIN;

🧯 If You Can't Patch

  • Restrict plugin access to trusted users only and monitor for suspicious activity.
  • Use web application firewalls (WAF) to block CSRF and XSS payloads.

🔍 How to Verify

Check if Vulnerable:

Check the HidePost plugin version in WordPress admin under Plugins > Installed Plugins; if version is 2.3.8 or lower, it is vulnerable.

Check Version:

wp plugin get hidepost --field=version

Verify Fix Applied:

After updating, confirm the HidePost plugin version is 2.3.9 or higher in the WordPress admin panel.

📡 Detection & Monitoring

Log Indicators:

  • Unusual POST requests to HidePost endpoints without referrer headers or CSRF tokens
  • Multiple failed CSRF attempts in WordPress logs

Network Indicators:

  • HTTP requests with suspicious parameters targeting HidePost plugin URLs
  • Traffic patterns indicating CSRF attack vectors

SIEM Query:

source="wordpress.log" AND ("hidepost" OR "CSRF") AND status=200
