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
ActiveCollab before 2.3.2 allows remote authenticated users to bypass intended access restrictions, and (1) delete an attachment or (2) subscribe to an object, via a crafted URL.

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 confidence

ActiveCollab before version 2.3.2 contains an insecure direct object reference (IDOR) vulnerability where authenticated users can bypass access restrictions by manipulating URLs to delete attachments they shouldn't have permission to delete or subscribe to objects they shouldn't have access to. The application fails to properly validate user permissions on specific actions triggered through direct object references.

MitigationUpgrade to ActiveCollab version 2.3.2 or later which contains the access control fix. If immediate patching is not possible, implement application-level permission checks on all attachment deletion and subscription operations to verify the authenticated user has appropriate object-level authorization.

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 ActiveCollab is installed
    Look for ActiveCollab web application files in the web server document root or check for activecollab directories in the web application deployment path.
    Affected if ActiveCollab is present on the system
  2. Determine the installed ActiveCollab version
    Check the version file or admin panel: Look for a version.php, version.txt, or check the application footer in the web interface for the version number.
    Affected if The installed version is 2.3.1 or earlier (versions <= 2.3.1 are affected)
  3. Verify the application uses the vulnerable URL-based attachment deletion
    Examine the attachment deletion URLs in the application. The vulnerability allows deletion via direct URL manipulation (for example, requests to attachment/delete or similar endpoints without proper permission checks). Check if the application accepts delete requests for attachments without verifying the user's object-level permissions.
    Affected if The application processes attachment deletion requests without validating user permissions on the specific object
  4. Check if the subscription feature allows unauthorized access
    Review the subscription functionality endpoints. The IDOR vulnerability allows authenticated users to subscribe to objects they should not have access to by directly referencing object IDs in subscription URLs. Test whether users can subscribe to objects outside their authorized projects.
    Affected if The subscription endpoint accepts and processes requests for objects without verifying the user has access to that specific object

The environment is affected if ActiveCollab version 2.3.1 or earlier is installed and the application exposes attachment deletion or subscription functionality via direct URL access without proper object-level permission validation.

From vendor data
Upgrade available Upgrade to a release after 2.3.1
Interim mitigation

Upgrade to ActiveCollab version 2.3.2 or later which contains the access control fix. If immediate patching is not possible, implement application-level permission checks on all attachment deletion and subscription operations to verify the authenticated user has appropriate object-level authorization.
