CVE-2025-6517
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 · uneditedA vulnerability was found in Dromara MaxKey up to 4.1.7 and classified as critical. This issue affects the function Add of the file maxkey-webs\maxkey-web-mgt\src\main\java\org\dromara\maxkey\web\apps\contorller\SAML20DetailsController.java of the component Meta URL Handler. The manipulation of the argument post leads to server-side request forgery. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 · high confidenceServer-side request forgery (SSRF) vulnerability in Dromara MaxKey's SAML20DetailsController component allows remote attackers to make the server perform arbitrary requests via manipulation of the 'post' argument in the Add function. The Meta URL Handler lacks proper validation of user-supplied URLs before making requests.

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 MaxKey versionLocate the MaxKey installation and check the version number (typically found in the application metadata, about page, or version file). Compare against the affected range: version 4.1.7 or lower.Affected if MaxKey version is 4.1.7 or lower (any version up to and including 4.1.7).
-
Verify SAML20DetailsController endpoint existsCheck if the application exposes the SAML20DetailsController endpoint (typically at a path containing 'saml20' or 'SAML20'). This is the vulnerable component.Affected if The SAML20DetailsController is present in the deployed MaxKey application.
-
Confirm Meta URL Handler feature is enabledDetermine whether the Meta URL Handler functionality is active in the MaxKey configuration. This feature handles the 'post' parameter that can be manipulated.Affected if Meta URL Handler is enabled and accessible to users who can trigger the Add function.
-
Test 'post' parameter for SSRFIf you have access, send a request to the Add function of SAML20DetailsController with an attacker-controlled URL in the 'post' parameter and observe if the server makes an outbound request.Affected if The server accepts arbitrary URLs in the 'post' parameter and fetches them, indicating the SSRF vulnerability is present.
You are affected if your MaxKey version is 4.1.7 or lower AND the Meta URL Handler (SAML20DetailsController) is enabled and accessible to your users.

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 strict allowlist validation for URL inputs in the SAML20DetailsController Add function, restricting allowed protocols and destinations to trusted endpoints only. Consider disabling or restricting the Meta URL Handler feature if not business-critical.
