CVE-2025-32624 Overview
CVE-2025-32624 is a Missing Authorization vulnerability [CWE-862] in the Czater.pl – live chat i telefon WordPress plugin developed by czater. The flaw enables Cross-Site Request Forgery (CSRF) that can escalate to stored Cross-Site Scripting (XSS). The vulnerability affects all plugin versions up to and including 1.0.5. An unauthenticated attacker can craft a malicious request that, when triggered by an authenticated administrator, executes privileged actions and persists attacker-controlled script content within the WordPress site.
Critical Impact
A successful attack lets a remote actor inject stored XSS payloads into a WordPress site by tricking an administrator into visiting a malicious page, leading to session theft, content tampering, or further compromise of site visitors.
Affected Products
- Czater.pl – live chat i telefon WordPress plugin versions through 1.0.5
- WordPress sites running the vulnerable czater plugin
- Administrator user sessions interacting with the plugin

Technical Details for CVE-2025-32624
Vulnerability Analysis
The vulnerability stems from missing authorization checks in state-changing handlers within the Czater.pl WordPress plugin. The plugin does not verify a valid CSRF nonce or capability check before processing administrative requests. An attacker who lures an authenticated WordPress administrator to a malicious URL or page can trigger requests that modify plugin settings on the target site. Because the modified settings are rendered without sufficient output sanitization, attacker-supplied content is stored and later executed as JavaScript in the context of the WordPress site. This chains a CSRF condition into a persistent stored XSS payload that runs whenever a victim loads an affected page.
Root Cause
The root cause is the absence of authorization and request-origin validation [CWE-862]. The plugin's request handlers omit WordPress nonce verification via check_admin_referer() or wp_verify_nonce(), and they do not enforce capability checks such as current_user_can('manage_options') before persisting input. Combined with insufficient output encoding, untrusted values reach the DOM unescaped.
Attack Vector
Exploitation requires network access and user interaction: the victim must be an authenticated administrator who visits an attacker-controlled page or clicks a crafted link. The attacker hosts an HTML form or auto-submitting JavaScript that issues a forged POST request to the plugin's vulnerable endpoint. Once the administrator's browser submits the request with their session cookies, the plugin stores the attacker's payload, which subsequently executes as stored XSS. Full technical details are available in the Patchstack WordPress Vulnerability Advisory.
Detection Methods for CVE-2025-32624
Indicators of Compromise
- Unexpected <script> tags, event handlers, or obfuscated JavaScript stored in czater plugin settings within the WordPress database.
- WordPress administrator activity logs showing plugin configuration changes without a corresponding admin-initiated session.
- HTTP POST requests to czater plugin admin endpoints lacking valid _wpnonce parameters.
- Outbound requests from administrator browsers to unfamiliar domains shortly after loading affected admin pages.
Detection Strategies
- Review the wp_options table and plugin-specific options for HTML or JavaScript content that should contain only plain text or numeric values.
- Inspect web server access logs for cross-origin POST requests targeting czater plugin admin-post or AJAX endpoints.
- Run a WordPress vulnerability scanner such as WPScan or Patchstack to identify installations of the czater plugin at version 1.0.5 or earlier.
Monitoring Recommendations
- Enable WordPress audit logging to capture option changes, plugin updates, and administrator actions with source IP attribution.
- Deploy a Web Application Firewall (WAF) rule set that blocks state-changing requests missing valid origin or referer headers.
- Monitor browser Content Security Policy (CSP) violation reports for inline script execution on /wp-admin/ pages.
How to Mitigate CVE-2025-32624
Immediate Actions Required
- Update the Czater.pl – live chat i telefon plugin to a version newer than 1.0.5 once the vendor publishes a fix.
- Audit the plugin's stored settings for injected script content and remove any unauthorized values before restoring service.
- Rotate WordPress administrator passwords and invalidate active sessions if exploitation is suspected.
Patch Information
At the time of NVD publication, the advisory indicates the vulnerability affects versions from n/a through 1.0.5. Consult the Patchstack WordPress Vulnerability Advisory for the latest patched version and vendor remediation guidance.
Workarounds
- Deactivate and remove the czater plugin until a patched release is verified.
- Restrict /wp-admin/ access by IP allowlist and require administrators to authenticate through a separate browser profile that does not visit untrusted sites.
- Enforce a strict Content Security Policy on the WordPress admin interface to limit inline script execution.
# Configuration example: WordPress CLI commands to disable the vulnerable plugin
