CVE-2025-57912 Overview
CVE-2025-57912 is a stored Cross-Site Scripting (XSS) vulnerability [CWE-79] in the Dialogity Free Live Chat WordPress plugin (dialogity-website-chat). The flaw affects all versions from initial release through 1.0.3. Attackers with high privileges can inject malicious scripts that persist in the plugin's stored data and execute in the browsers of users who view the affected pages.
The vulnerability results from improper neutralization of user input during web page generation. Successful exploitation requires user interaction and can lead to session compromise, redirection, or content manipulation within the scope of the affected WordPress site.
Critical Impact
Authenticated attackers can inject persistent JavaScript payloads that execute in visitors' and administrators' browsers, enabling session theft and unauthorized actions.
Affected Products
- Dialogity Free Live Chat WordPress plugin (dialogity-website-chat)
- All versions up to and including 1.0.3
- WordPress installations with the plugin activated

Technical Details for CVE-2025-57912
Vulnerability Analysis
The Dialogity Free Live Chat plugin fails to properly sanitize and encode user-supplied input before rendering it in generated web pages. This is a classic stored XSS pattern where attacker-controlled data is persisted server-side and later reflected to other users without adequate output encoding.
Because the injected payload persists in storage, every user who loads an affected page executes the malicious script in their browser session. The scoped impact (S:C in CVSS terms) means the vulnerability can affect resources beyond the vulnerable component itself, such as the broader WordPress admin context.
Root Cause
The root cause is missing or insufficient input sanitization and output encoding in the plugin's request handlers responsible for storing and rendering chat-related content. Input intended for display is written to persistent storage and later emitted into HTML without contextual escaping, allowing <script> tags or event-handler attributes to survive rendering.
Attack Vector
An authenticated attacker with elevated privileges submits crafted input to a plugin field that stores the value. When another authenticated user, such as an administrator, loads a page that renders the stored content, the browser parses the injected payload as executable JavaScript. Exploitation requires the target to interact with the affected interface.

Detection Methods for CVE-2025-57912
Indicators of Compromise
- Unexpected <script>, <iframe>, or event-handler attributes (onerror=, onload=) stored in plugin database tables or options
- Outbound requests from admin browsers to attacker-controlled domains after loading plugin pages
- Newly created WordPress administrator accounts or unauthorized changes to user roles following plugin usage
- Modified plugin configuration entries containing encoded JavaScript payloads
Detection Strategies
- Inspect the WordPress database for HTML or JavaScript content stored in fields managed by the Dialogity plugin
- Enforce a strict Content Security Policy (CSP) and monitor CSP violation reports for inline script execution attempts
- Review web server access logs for suspicious POST requests targeting plugin endpoints with script tags in parameters
Monitoring Recommendations
- Audit administrator session activity for anomalous actions immediately following visits to plugin-managed pages
- Alert on modifications to WordPress user accounts, roles, or plugin settings by unexpected accounts
- Monitor outbound HTTP requests from browsers accessing the WordPress admin interface for beaconing behavior
How to Mitigate CVE-2025-57912
Immediate Actions Required
- Deactivate the Dialogity Free Live Chat plugin until a patched version is confirmed available
- Restrict high-privilege WordPress accounts and require multi-factor authentication for administrators
- Review stored plugin data and remove any entries containing HTML or script content
- Rotate credentials and invalidate active sessions for any account that may have interacted with the plugin
Patch Information
No fixed version is currently identified in the CVE record; all versions through 1.0.3 are affected. Monitor the Patchstack Vulnerability Report and the plugin's WordPress.org page for an official patched release.
Workarounds
- Remove or disable the plugin entirely if a patched version is unavailable
- Deploy a Web Application Firewall (WAF) rule to block requests containing script tags or JavaScript event handlers targeting plugin endpoints
- Apply a restrictive Content Security Policy that disallows inline scripts and untrusted script sources
- Limit accounts eligible to configure the plugin to a minimal set of trusted administrators
# Example restrictive Content-Security-Policy header for WordPress
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self'"
