CVE-2025-22345 Overview
CVE-2025-22345 is a reflected cross-site scripting (XSS) vulnerability in the tsinf TS Comfort DB (ts-comfort-database) WordPress plugin. The flaw affects all versions up to and including 2.0.7. The plugin fails to properly neutralize user-supplied input before reflecting it into web page output, allowing attackers to execute arbitrary JavaScript in a victim's browser. The vulnerability is classified under CWE-79 and requires user interaction, typically by tricking a victim into clicking a crafted link.
Critical Impact
Successful exploitation enables session hijacking, credential theft, and unauthorized actions performed in the context of authenticated users including administrators.
Affected Products
- tsinf TS Comfort DB (ts-comfort-database) WordPress plugin
- All versions from initial release through 2.0.7
- WordPress installations with the affected plugin enabled

Technical Details for CVE-2025-22345
Vulnerability Analysis
The vulnerability stems from improper neutralization of user-controlled input during web page generation. The TS Comfort DB plugin reflects request parameters back into HTTP responses without applying contextual output encoding or input sanitization. An attacker crafts a URL containing malicious JavaScript payloads in vulnerable parameters. When a victim clicks the link, the payload executes within the origin of the WordPress site.
The issue has a changed scope, meaning the injected script can affect resources beyond the vulnerable component. Because the attack delivers script execution in an authenticated user's browser context, attackers can read session tokens, perform privileged actions, or pivot to administrative functionality.
Root Cause
The root cause is missing output encoding when handling reflected request data. The plugin inserts attacker-controlled values into HTML, JavaScript, or attribute contexts without applying functions such as esc_html(), esc_attr(), or wp_kses(). WordPress provides these sanitization primitives, but the affected plugin code paths do not invoke them on the reflected parameters.
Attack Vector
Exploitation occurs over the network and requires user interaction. An attacker constructs a malicious URL targeting a vulnerable endpoint exposed by the plugin and delivers it via phishing email, social media, or a malicious referring site. When the victim loads the URL while authenticated to the WordPress site, the reflected payload executes in their browser session. Because no privileges are required from the attacker side, anonymous threat actors can launch campaigns at scale. See the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-22345
Indicators of Compromise
- HTTP request logs containing URL parameters with <script>, javascript:, onerror=, or onload= payloads targeting ts-comfort-database endpoints
- Unexpected outbound requests from administrator browsers to attacker-controlled domains following clicks on suspicious links
- WordPress audit log entries showing privileged actions originating from anomalous referrers
Detection Strategies
- Inspect web server access logs for crafted query strings directed at plugin paths containing URL-encoded HTML or script tokens
- Deploy a web application firewall (WAF) with rules that block reflected XSS payload patterns on WordPress plugin routes
- Correlate browser-based telemetry with server logs to identify successful payload execution and downstream account compromise
Monitoring Recommendations
- Enable verbose logging of all requests to /wp-content/plugins/ts-comfort-database/ and review for parameter tampering
- Monitor administrator session activity for unusual API calls, content modifications, or user creation events
- Track Content Security Policy (CSP) violation reports to surface injection attempts blocked at the browser
How to Mitigate CVE-2025-22345
Immediate Actions Required
- Update the TS Comfort DB plugin to a version released after 2.0.7 once the vendor publishes a fix
- Disable or remove the ts-comfort-database plugin from WordPress installations until a patched release is verified
- Rotate administrator credentials and invalidate active sessions if exploitation is suspected
Patch Information
At the time of publication, the Patchstack advisory confirms the issue affects versions up to and including 2.0.7. Administrators should monitor the WordPress plugin repository and the vendor's release notes for an updated build that addresses the reflected XSS flaw.
Workarounds
- Deploy a WAF rule set that filters reflected XSS payloads targeting WordPress plugin endpoints
- Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
- Restrict access to the WordPress administration interface using IP allowlisting or VPN-only access to reduce phishing exposure
# Example Apache WAF rule to block common reflected XSS payloads
SecRule ARGS "@rx (?i)(<script|javascript:|onerror=|onload=)" \
"id:1009001,phase:2,deny,status:403,msg:'Reflected XSS attempt blocked'"
