AWS Security Agent plugin can expose private scan archives

CVE-2026-87912 · published 1 month ago
Summary

The AWS Security Agent plugin may let an attacker retrieve the private source archive of a scanned workspace if the storage bucket is not owned by your account. Upgrade to version 1.1.0 and confirm that the scan output bucket is registered to your own AWS account to prevent unauthorized access.

What to do

The CVE record does not list a fixed version. Check the vendor's site or the advisory links below - a fix may already be released.

Original advisory text
Missing S3 bucket ownership verification in the AWS Security Agent plugin for aws-agents-for-devsecops
A missing S3 bucket ownership verification in the AWS Security Agent plugin in Amazon aws-agents-for-devsecops before 1.1.0 might allow remote attackers to obtain the private source archive of a scanned workspace, including credentials and infrastructure state contained in that archive, via a pre-registered storage bucket whose name is derived from a publicly known account identifier.



To remediate this issue, users should upgrade to version 1.1.0. Users should also verify that the scan output bucket in their account is owned by their own account, because upgrading does not release a bucket name that a third party has already registered.
