CVE-2025-30558
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 EnzoCostantini55 ANAC XML Render anac-xml-render allows Stored XSS.This issue affects ANAC XML Render: from n/a through <= 1.5.7.
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 ANAC XML Render <= 1.5.7 allows attackers to craft malicious requests that execute in the context of authenticated users, leading to stored XSS where malicious scripts are persisted in the application and executed when other users view the compromised content.

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 ANAC XML Render installationLocate the application files or running service for ANAC XML Render on the system. Check for directories or components named 'anac', 'xml-render', or similar.Affected if ANAC XML Render is present on the system
-
Check installed versionExamine version files, build metadata, or application headers to determine the exact version number. Compare against 1.5.7.Affected if Version is 1.5.7 or lower
-
Verify XML input handling configurationInspect application configuration files to determine if the XML rendering feature accepts input from users or external sources without sanitization.Affected if XML rendering is enabled for user-supplied content without input validation
-
Inspect for stored malicious contentSearch the application's database or content storage for any persisted scripts or suspicious payload patterns (script tags, javascript: URIs, event handlers). Review any stored XML content that gets rendered.Affected if Stored XSS payloads exist in the application's persisted content
-
Review CSRF protection mechanismsExamine the application's request handling for anti-CSRF tokens, Origin/Referer header validation, or SameSite cookie attributes on session cookies.Affected if No anti-CSRF tokens or SameSite cookie attributes are implemented for state-changing operations
A user is affected if ANAC XML Render version 1.5.7 or lower is installed, the XML rendering feature processes user-supplied content without sanitization, and the application lacks CSRF protections such as anti-CSRF tokens or SameSite cookies.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement anti-CSRF tokens for all state-changing operations, validate Origin/Referer headers, and apply SameSite cookie attributes. Additionally, implement output encoding and Content Security Policy headers to mitigate the XSS component.
