Overview
On December 13, 2025, a critical vulnerability was disclosed for TI WooCommerce Wishlist affecting versions ≤ 2.10.0. The flaw allows unauthenticated actors to inject arbitrary HTML content into pages and posts, potentially leading to phishing, SEO spam, and client-side attacks. Managed-WP, a US-based WordPress security provider, highlights the importance of swift action due to the broad impact unauthorized content injection can cause.
Despite a moderately rated CVSS score (5.3), the real-world consequences are significant and may result in long-lasting damage to your brand and user trust.
What is an Unauthenticated HTML (Content) Injection?
This vulnerability allows an attacker to insert HTML directly into your website’s pages or posts without needing to be logged in. Such injections can include malicious scripts, deceptive forms, or SEO-spam content designed to manipulate users or search rankings.
- Phishing content to steal credentials or payments
- SEO spam that harms your search rankings
- Drive-by downloads or client-side exploits using HTML elements
- Severe erosion of customer trust and potential blacklisting
Since the malicious content runs on your legitimate domain, users are more likely to trust it, compounding the impact.
Vulnerability Summary: TI WooCommerce Wishlist (≤2.10.0)
- Plugin: TI WooCommerce Wishlist (WordPress)
- Affected Versions: All versions up to 2.10.0
- Fixed In: Version 2.11.0
- Vulnerability Type: Unauthenticated HTML/Content Injection
- Attack Vector: HTTP, no authentication required
- CVE Identifier: CVE-2025-9207
- Disclosure Date: December 13, 2025
- Reported By: Public security researcher
In brief, unauthenticated attackers can submit crafted requests that insert arbitrary HTML into site content, allowing persistent manipulation of visible pages.
Technical Analysis: How Attackers Exploit This Flaw
The vulnerability stems from insufficient input validation and sanitization in endpoints accepting wishlist-related data:
- Improper Input Sanitization: User inputs such as item notes or descriptions are accepted without proper escaping.
- Stored Injection: Malicious HTML is stored persistently, affecting any visitor viewing the compromised content.
- Unauthenticated Access: Attackers can exploit the plugin’s publicly accessible endpoints or AJAX calls without needing login credentials.
- Payload Capabilities: Injected HTML can include phishing forms, iframes, or minimal JavaScript enabling further exploits.
- Mass Automation Risk: Bots may automate injection attempts widely, increasing exposure.
Potential Impact Scenarios
Depending on your website type, this vulnerability poses different risks:
- Small WooCommerce Shops: Phishing forms harvesting payment info, SEO spam reducing sales.
- Enterprise Marketplaces: Reputation damage from search engine delisting, customer fraud reports.
- Membership/Training Sites: Session token theft, fake announcements compromising trust.
- Informational Blogs: SEO poisoning, outbound malicious links harming rankings.
Even non-commercial sites can face serious reputational harm and expensive recovery processes.
Immediate Actions (Within 24 Hours)
- Update TI WooCommerce Wishlist: Upgrade to version 2.11.0 or later immediately.
- Create Full Backup: Backup all files and database before applying any changes.
- Apply WAF Virtual Patching: Use Web Application Firewall rules to block known attack patterns targeting wishlist endpoints.
- Deactivate If Necessary: Temporarily disable the plugin if you cannot immediately update.
- Notify Stakeholders: Inform site owners and teams about mitigations in progress.
- Increase Log Monitoring: Look for suspicious wishlist-related requests in server logs.
Detection & Investigation Tips
Search for Injected HTML
- Look for markers: <script, <iframe, onerror=, javascript:, hidden forms
- Example SQL for checking wp_posts content:
SELECT ID, post_title, post_status FROM wp_posts WHERE post_content LIKE '%<script%' OR post_content LIKE '%<iframe%' OR post_content LIKE '%javascript:%' LIMIT 100;
- Check wp_postmeta similarly for suspicious content.
Review Recent Content
- Sort by date and audit pages, posts, and wishlists for anomalies.
Inspect File System
- Search for recently modified PHP, HTML, or JavaScript files.
find /path/to/site -type f -mtime -14 -iname '*.php' -o -iname '*.html' -o -iname '*.js' | less
Analyze Logs
- Look for suspicious POST or AJAX requests to plugin endpoints.
- Identify abnormal IPs and user agents.
Use Malware Scanners
- Run comprehensive scans to detect injected content and threats.
Containment & Remediation (If Compromised)
- Isolate the Site: Place into maintenance mode to prevent user exposure.
- Remove Malicious Content: Clean injected HTML or restore from clean backup.
- Rotate Credentials: Reset admin passwords, API keys, and database passwords.
- Reinstall Clean Plugins: Replace themes/plugins from verified sources.
- Eliminate Backdoors: Search common persistence locations and remove unauthorized files.
- Remove Phishing Artifacts: Delete linked malicious domains and submit reclassifications.
- Harden Post-Incident: Update all components, minimize plugins, fix permissions.
- Report Incidents: Follow legal requirements if user data was exposed, document steps.
Long-Term Mitigation and Best Practices
- Keep WordPress core, plugins, and themes up to date with tested workflows.
- Maintain a minimal plugin inventory; remove unused plugins.
- Apply least-privilege principles for user roles and access.
- Harden or disable unnecessary AJAX endpoints.
- Deploy a Web Application Firewall for virtual patching and attack blocking.
- Implement Content Security Policies (CSP) as an additional defense layer.
- Set up monitoring and alerting for suspicious traffic and file changes.
- Conduct regular vulnerability scans and code reviews.
- Use staging environments for testing updates before production.
- Establish an incident response plan with defined runbooks and communication channels.
Recommended WAF Rules (Examples)
Deploy virtual patching with rules that detect and block typical payloads targeting the vulnerable plugin. Adapt these examples to your WAF product syntax:
General Conditions:
- Block POST/GET requests to “wishlist” or related TI WooCommerce Wishlist endpoints
- Inspect parameters for regex matches: (<script|<iframe|onerror=|javascript:)
ModSecurity Conceptual Rule:
SecRule REQUEST_URI "@rx wishlist|ti_wishlist|ti-wishlist" "phase:2,deny,id:10001,msg:'Block potential content injection targeting wishlist plugin',t:none,t:lowercase,chain" SecRule ARGS|ARGS_NAMES|REQUEST_BODY "@rx (<script|<iframe|onerror\s*=|javascript:)" "t:none,log"
Nginx + Lua Conceptual Rule:
if ($request_uri ~* "wishlist|ti_wishlist") {
if ($request_body ~* "(<script|<iframe|onerror=|javascript:)") {
return 403;
}
}
Additional recommendations:
- Rate-limit POSTs to wishlist endpoints to mitigate automated mass injection.
- Geofence or reputation-block high-risk IPs exhibiting malicious behavior.
- Test rules in detection mode before activating blocking features.
Monitoring and Follow-Up
- Monitor for at least 30 days for re-injection or suspicious activity.
- Maintain blocklists for repeat offenders carefully to avoid unintended access blocks.
- Conduct routine weekly scans and monthly plugin reviews to maintain hygiene.
- Agencies and site managers: automate scanning and patching workflows across your portfolio.
Frequently Asked Questions
Q: If I updated to 2.11.0, is scanning still necessary?
A: Yes. Updating prevents future injection but does not remove existing malicious content. Clean your site thoroughly.
Q: My site doesn’t use wishlist features actively. Do I need to act?
A: Yes. Even inactive plugins expose endpoints attackers can target. Update or remove the plugin promptly.
Q: Could this lead to remote code execution?
A: Primarily, it is an HTML injection flaw. However, injected content can contain JavaScript leading to indirect compromises.
Q: Can a WAF fully protect my site?
A: A WAF provides strong interim protection but must be combined with vendor patches and proper updates for full security.
