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 · unedited
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in HelloAsso HelloAsso helloasso.This issue affects HelloAsso: from n/a through <= 1.1.9.

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 confidence

Cross-site scripting (XSS) vulnerability in HelloAsso web application allows attackers to inject malicious scripts through unsanitized user inputs that get rendered in web pages. The vulnerability affects versions up to and including 1.1.9.

MitigationImplement proper input validation and output encoding/sanitization for all user-supplied data before rendering in HTML context. Use established encoding libraries appropriate to the output context (HTML, JavaScript, URL).

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if HelloAsso is deployed
    Search your web server logs, application inventory, or installed packages for HelloAsso web application components. Check for processes or services named 'helloasso' or URLs containing '/helloasso/' path.
    Affected if HelloAsso web application is present in the environment
  2. Locate the installed version
    Check the application's version file, about page, or API endpoint that exposes version information. Common locations: version.json, manifest file, or the footer of the web interface.
    Affected if Version cannot be determined or is visible as a version number
  3. Compare against affected range
    Compare your installed version to the affected range: versions below 1.1.10 (including 1.1.9 and earlier) are vulnerable. Any version 1.1.10 or higher is not affected by this specific CVE.
    Affected if Installed version is less than 1.1.10
  4. Identify user input rendering points
    Examine the application for forms, search fields, comment sections, or any feature that accepts user input and displays it back in web pages. Look for GET/POST parameters that get reflected in HTML response without visible sanitization.
    Affected if User input fields exist and are rendered in HTML pages without confirmed sanitization

You are affected if HelloAsso is deployed and the installed version is below 1.1.10 and user-supplied data can be rendered in web pages without sanitization.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Upgrade available Upgrade to 1.1.10 or later
Fixed in 1.1.10
Interim mitigation

Implement proper input validation and output encoding/sanitization for all user-supplied data before rendering in HTML context. Use established encoding libraries appropriate to the output context (HTML, JavaScript, URL).

Recommended fix Moderate confidence

HelloAsso version 1.1.10

  1. 1. Ensure you have a backup of your current HelloAsso installation before proceeding.
  2. 2. Check your current HelloAsso version to confirm it is <= 1.1.9.
  3. 3. Upgrade HelloAsso to version 1.1.10 or later which contains the fix for the XSS vulnerability.
  4. 4. Verify the upgrade was successful by checking the new version number.
  5. 5. Test the application to confirm the XSS vulnerability has been remediated.
