How to fix it

OSOS through 09072026 is affected by CVE-2026-1365. Because the CVE record notes no vendor response, prioritize containment: the issue is sensitive information sent in data can support authentication bypass. Reduce exposure and monitor until a vendor patch or replacement is available.

  1. Identify every OSOS deployment, especially public or partner-facing instances.
  2. Ask the vendor for a fixed release and document the mitigation timeline.
  3. Restrict access to trusted networks, VPN, or allowlisted users until a patch is available.
  4. Review authorization logic around user-controlled IDs, keys, account IDs, and group identifiers.
  5. Add compensating server-side validation where customization is possible.
  6. Review audit logs for access to records that do not belong to the requesting user.
  7. Prepare a rollback, isolation, or replacement plan if vendor remediation remains unavailable.

Verify the fix

  • Confirm vulnerable functions are patched, disabled, isolated, or protected by compensating controls.
  • Attempt a safe ID/key substitution test in staging and confirm cross-account access fails.
  • Review logs for suspicious identifier enumeration before and after mitigation.
  • Confirm legitimate users can still access their own records only.
  • Run a Fixnx scan and confirm public application exposure has been rechecked.
