# CVE-2026-87912

## Summary

- **CVE ID:** CVE-2026-87912
- **Severity:** MEDIUM
- **CVSS Score:** 5.9 (CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:L/SA:N)
- **CWE:** CWE-283, CWE-341
- **Published:** Sep 10, 2026
- **Last Modified:** Sep 10, 2026

## Description

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.

## Affected Products

- AWS — AWS Security Agent plugin (1.0.0)
