Archive Operating System (AOS 7.4.2) Release Notes

What Is a Local Privilege Escalation Vulnerability?

A local privilege escalation (LPE) vulnerability is a class of security flaw that allows a user or process operating at a lower permission level to gain elevated system privileges, sometimes up to full administrative or root access.

Unlike remote code execution flaws, LPE vulnerabilities require some degree of existing access to the system, but once exploited, they can allow an attacker to bypass access controls, tamper with system processes, or access data outside their authorized scope.

In an archiving environment, where the integrity and confidentiality of retained communications is paramount, this type of vulnerability poses a direct risk to compliance obligations and audit defensibility. Patching it is not merely a best practice, it is a compliance necessity.

What Changed
The underlying issue behind CVE-2026-31431 has been identified and resolved in AOS 7.4.2. All customers running AOS 7 are strongly encouraged to upgrade immediately to ensure their deployments reflect this fix. If you have questions about the scope or impact of this vulnerability in your specific environment, please reach out to Intradyn Support.

AOS 6 to AOS 7 Migration Reliability
Migrating a production archive from one major platform version to another is one of the most operationally sensitive tasks an Intradyn administrator can undertake. The data involved spans years of communications, legal holds, and compliance records. There is no room for silent failures or incomplete transfers.

AOS 7.4.2 delivers a set of targeted bug fixes to the AOS 6 to AOS 7 migration pathway. These fixes address edge cases that could cause the migration process to stall, produce incomplete results, or behave inconsistently across different data configurations.

Who Is Affected

These improvements apply to any organization that is currently running the AOS 6 to AOS 7 migration process or planning to do so in the near future. If your migration previously encountered errors or required manual intervention to complete, upgrading to AOS 7.4.2 before retrying is recommended.

Google Workspace Crawler Reliability

For organizations using Google Workspace as their email platform, the Google Workspace Crawler is the engine that keeps your archive current. It continuously ingests new messages and ensures that your compliance record reflects what is actually happening in your mail environment. When the crawler is unreliable, coverage gaps appear, and in regulated industries, coverage gaps create risk.

AOS 7.4.2 introduces several targeted fixes to improve the reliability of the Google Workspace Crawler.

Why Crawler Reliability Matters

A compliant archive is only as good as its ingestion process. Organizations in regulated sectors, including government agencies, financial services firms, healthcare providers, and educational institutions, are required to retain communications completely and without gaps. Any failure in the crawler pipeline that results in missed messages is a potential compliance exposure.

The improvements in AOS 7.4.2 reduce the likelihood of these failures and make the crawler more resilient under the kinds of real-world conditions that production Google Workspace environments present.

This release reflects our ongoing commitment to keeping Intradyn’s platform secure, dependable, and ready for the demands of real-world compliance environments. We encourage all AOS 7 customers to upgrade to 7.4.2 to take advantage of the critical security patch, improved migration reliability, and a more resilient Google Workspace Crawler.
