CVE-2026-81822

AVEVA Pipeline Integrity Monitor Use of a Broken or Risky Cryptographic Algorithm

Published Sep 8, 2026 CVSS 4.0 · 8.3 High EPSS < 1% KEV · Not listed
Description
The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to reverse engineer PIMBoards users’ app-native passwords through computational brute-forcing of weak hashes, potentially allowing elevation to a PIMBoards administrator user.

Remediation

Vendor Solution

AVEVA Pipeline Simulation media delivers AVEVA Pipeline Integrity Monitor: * All affected versions can be fixed by upgrading to AVEVA Pipeline Integrity Monitor 2025 SP1 P2 or higher: https://softwaresupportsp.aveva.com/en-US/downloads/products/details/021a26a7-200f-44eb-8cc9-cd57b7e349aa


Vendor Workaround

AVEVA recommends the following general defensive measures: * Restrict Network Access: Implement host-based and/or network firewall controls on all nodes hosting the PIMBoards API to ensure that only trusted client systems are permitted to establish connections. * Apply strong Access Control Lists to all folders storing project files to ensure only trusted users have read-access. * Maintain a trusted chain-of-custody on project files during creation, modification, distribution, backups, and use.
