CVE-2024-44045
📋 TL;DR
This stored cross-site scripting (XSS) vulnerability in the WP Abstracts WordPress plugin allows attackers to inject malicious scripts into web pages that are then executed when other users view those pages. All WordPress sites using WP Abstracts versions up to 2.6.5 are affected. The vulnerability requires contributor-level access or higher to exploit.
💻 Affected Systems
- WP Abstracts (WordPress plugin)

⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker with contributor privileges could inject malicious JavaScript that steals administrator credentials, hijacks user sessions, defaces websites, or redirects visitors to malicious sites when administrators or users view affected pages.
Likely Case
Attackers with contributor access inject tracking scripts, cookie stealers, or defacement content that executes when administrators review submissions in the WP Abstracts interface.
If Mitigated
With proper input validation and output escaping, malicious scripts would be neutralized before reaching users' browsers, preventing execution.
🎯 Exploit Status
Exploitation requires authenticated access (contributor role minimum). Public proof-of-concept demonstrates stored XSS via abstract submission fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.6.6 or later
Restart Required: No
Instructions:
1. Log into WordPress admin panel. 2. Navigate to Plugins → Installed Plugins. 3. Find WP Abstracts and click 'Update Now'. 4. Alternatively, download version 2.6.6+ from WordPress.org and manually replace plugin files.
🔧 Temporary Workarounds
Input Validation Filter
allAdd custom input validation to sanitize abstract submission fields
Add to theme's functions.php or custom plugin: add_filter('wp_abstracts_submission_data', 'sanitize_abstract_input'); function sanitize_abstract_input($data) { foreach($data as $key => $value) { $data[$key] = wp_kses_post($value); } return $data; }
Role Restriction
allTemporarily restrict contributor role submissions until patched
Install and configure a role management plugin like 'User Role Editor' to disable abstract submission capabilities for contributor role
🧯 If You Can't Patch
- Disable WP Abstracts plugin completely until patched
- Implement web application firewall (WAF) rules to block XSS payloads in abstract submissions
🔍 How to Verify
Check if Vulnerable:
Check WordPress admin → Plugins → Installed Plugins → WP Abstracts version. If version is 2.6.5 or lower, you are vulnerable.Check Version:
wp plugin list --name=wp-abstracts --field=version (WP-CLI) or check WordPress admin plugins pageVerify Fix Applied:
After updating, verify WP Abstracts version shows 2.6.6 or higher in WordPress plugins list.📡 Detection & Monitoring
Log Indicators:
- Unusual abstract submissions containing script tags or JavaScript code
- Multiple failed login attempts followed by abstract submissions
Network Indicators:
- HTTP POST requests to /wp-admin/admin-ajax.php or abstract submission endpoints containing script payloads
SIEM Query:
source="wordpress.log" AND ("wp_abstracts" OR "abstract submission") AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
