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
ITFlow provides an IT documentation, ticketing and accounting system for small managed service providers. Prior to version 26.05, low-privileged authenticated agent can retrieve plaintext credentials and TOTP secrets belonging to another client by directly requesting the credential edit modal with an arbitrary `credential_id`. The endpoint does not enforce client scoping or object-level authorization before loading and decrypting the credential record. Version 26.05 fixes the issue.

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 · 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.

Recommended fix High confidence

26.05

  1. 1. Backup your ITFlow database and configuration files before performing any upgrade.
  2. 2. Download ITFlow version 26.05 from the official GitHub repository or your update mechanism.
  3. 3. Review the upgrade instructions provided in the release notes for version 26.05.
  4. 4. Apply the upgrade to your ITFlow instance.
  5. 5. After upgrading, verify that the fix is working by testing that a low-privileged agent cannot access credentials from another client using an arbitrary credential_id.
  6. 6. Confirm that client scoping and object-level authorization are now properly enforced for credential operations.
