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
A vulnerability was identified in OWASP DefectDojo 2.59.0. This issue affects the function UserSerializer of the file dojo/api_v2/serializers.py of the component API/Web. Such manipulation of the argument is_staff leads to improper privilege management. The attack may be performed from remote. The exploit is publicly available and might be used. Upgrading to version 2.58.3 and 3.0.0 is capable of addressing this issue. The name of the patch is 68a272f299d096249fd3ba9c2676bf69012857bf. It is advisable to upgrade the affected component. 2.59.0 was not intended to be released and has been removed.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-06.

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.

Recommended fix Moderate confidence

DefectDojo 3.0.0 (or 2.58.3 if 3.x migration is not feasible)

  1. 1. Identify the current DefectDojo version in your environment
  2. 2. If running version 2.59.0, note that this version was not intended for release and should be replaced
  3. 3. Upgrade to DefectDojo version 3.0.0 (the stable release that contains the fix)
  4. 4. Alternatively, if 3.x is not feasible in your environment, verify if version 2.58.3 is available and appropriate for your deployment
  5. 5. After upgrading, verify that the UserSerializer no longer allows modification of the is_staff parameter through the API
  6. 6. Confirm that existing admin privileges are correctly maintained and no unauthorized privilege escalation occurred
Caveat Upgrading to DefectDojo 3.x may include breaking changes from 2.x; review the 3.0.0 release notes for migration requirements

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
