CVE-2026-81326

Administrator credential disclosure via hard-coded cryptographic key

Published Sep 16, 2026 · Updated Sep 16, 2026

Use of a hard-coded cryptographic key in QualitySoft QND Windows clients allows local users to obtain configured administrator credentials. The client relies on the same embedded cryptographic key to protect administrator IDs and passwords instead of a deployment-specific secret. The attacker must have a general user login on a PC running Premium or Standard 11.1i and earlier or Advance 11.0.9i and earlier; the reported impact is credential disclosure only.
