CVE-2025-25156
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCross-Site Request Forgery (CSRF) vulnerability in Stanko Metodiev Quote Comments quote-comments allows Stored XSS.This issue affects Quote Comments: from n/a through <= 3.0.0.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA CSRF vulnerability in the Quote Comments plugin allows attackers to craft malicious requests that inject JavaScript code into comments, which gets stored (Stored XSS). When other users view these injected comments, the malicious script executes in their browsers, potentially stealing session cookies or performing actions on behalf of authenticated users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Quote Comments plugin is installedLocate the plugin directory in your CMS (e.g., WordPress wp-content/plugins/ directory, or similar path for other platforms). Look for a folder named 'quote-comments', 'quote-comments-plugin', or similar variations.Affected if The plugin directory does not exist or the plugin is not found in your system.
-
Determine installed version of Quote CommentsCheck the plugin's main file header (e.g., readme.txt, plugin.php, or index.php within the plugin folder) for the 'Version' field. Compare this version number against any affected version ranges published by the vendor or security advisories.Affected if Your installed version falls within a published affected range, or no version information is available and the plugin is installed.
-
Verify plugin is active or enabledAccess your CMS admin panel (e.g., WordPress Plugins page) and confirm whether Quote Comments is activated. For non-WordPress systems, check the application configuration or database for enabled plugins.Affected if The plugin is active and running on your site.
-
Confirm comment functionality is accessibleNavigate to a post, page, or area where comments are enabled on your site. Verify that the Quote Comments feature is functional and visible to users (e.g., quote/reply functionality on existing comments).Affected if The comment system with Quote Comments is live and accessible to users.
-
Inspect stored comments for unexpected script tagsAccess your database or comment moderation interface. Query recent comments for patterns like '<script>', 'javascript:', 'onerror=', 'onload=', or other HTML/script injection attempts in comment content fields.Affected if Comments contain unsanitized JavaScript code or HTML that could execute in a user's browser.
You are affected if the Quote Comments plugin is installed, active, and handling user comments without proper CSRF protection and output sanitization, allowing script injection to be stored and executed when viewed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply any available vendor patch. If no patch exists, implement anti-CSRF tokens on all state-changing operations and ensure proper output encoding/sanitization on comment display to prevent XSS execution.
