CVE-2026-81821

Sensitive-data decryption via hard-coded project-file key

Published Sep 8, 2026 · Updated Sep 8, 2026

Hard-coded cryptography in AVEVA Pipeline Integrity Monitor 2025 SP1 P1 and earlier allows local users to decrypt sensitive PIMBoards project data. PIMBoards encrypts project-file contents with key material embedded in the product, making the same key available for recovering protected information. Exploitation requires low-privileged local read access to an affected project file; the demonstrated consequence is disclosure of its protected contents.
