CVE-2026-25351
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 · uneditedImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in skygroup MyMedi mymedi allows Reflected XSS.This issue affects MyMedi: from n/a through < 1.7.7.
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 confidenceReflected XSS vulnerability in MyMedi web application allows attackers to inject malicious scripts via untrusted user input that gets rendered in the web page response without proper sanitization or output encoding.

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 MyMedi web application is deployedCheck for presence of MyMedi application files, or query the running web server for MyMedi-related endpoints or servicesAffected if The MyMedi web application is present in the environment
-
Determine MyMedi application versionReview application release notes, check about/help pages within the app, or inspect application configuration files for version metadataAffected if A specific version number cannot be confirmed or the version falls within an affected release range
-
Identify user input fields that lack sanitizationReview application source code or proxy traffic to locate endpoints that accept user input and reflect it back in HTTP responses without visible encodingAffected if User-supplied parameters are returned in responses without proper HTML entity encoding or context-aware escaping
-
Verify lack of output encoding in response handlingTest suspected parameters by submitting markup characters (e.g., <script>alert(1)</script>) and inspect if they render as literal text or execute in the browserAffected if Injected script content is executed or rendered as HTML rather than being escaped
If MyMedi is deployed and user input fields reflect unsanitized data directly into web page responses, the environment is affected by this reflected XSS vulnerability.
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.
dbcve · scopedImplement proper input validation and context-aware output encoding/escaping for all user-supplied data before rendering in HTML/JavaScript contexts to prevent script injection.
MyMedi version 1.7.7 or later
- 1. Backup your current MyMedi installation and database before making any changes
- 2. Download MyMedi version 1.7.7 or later from the official vendor repository
- 3. Replace the existing MyMedi files with the new version, preserving any custom configurations
- 4. Verify that all core application files have been updated to the new version
- 5. Test the application functionality to ensure the upgrade was successful
- 6. Confirm the XSS vulnerability is no longer present by reviewing the fixed code paths
