APSB26-153: Security update available for Adobe Commerce

Published Oct 13, 2026.

APSB26-153 (published 2026-10-13) discloses 11 CVEs in Adobe Commerce and Magento Open Source 2.4.9, 2.4.8-p5, 2.4.7-p10, 2.4.6-p15, 2.4.5-p17, 2.4.4-p18 and earlier; no fixing release yet; isolated patch 2026-oct.

Eleven vulnerabilities, five of them exploitable without authentication, led by a template engine injection (CVE-2026-103849, CVSS 10.0) that lets an unauthenticated attacker execute arbitrary code. Also fixes an incorrect authorization flaw in B2B allowing unauthenticated code execution (CVE-2026-92909, CVSS 9.8), stored cross-site scripting, and an admin input validation flaw allowing arbitrary file system writes. Adobe reports no exploitation in the wild. Adobe ships the fix as the 2026-oct isolated patch level on top of the base release, not as a new -pN release; Adobe asks merchants to apply the APSB26-146 hotfix in addition.
