CVE-2025-49558Network attack vector

Unauthorized writes via resource-state TOCTOU race

Published Aug 12, 2025 · Updated Feb 26, 2026

A TOCTOU race in Adobe Commerce 2.4.9-alpha1, 2.4.8-p1, and corresponding earlier release lines allows remote attackers to make unauthorized writes. Adobe describes a resource-state check followed by a separate use that timing manipulation can invalidate, but does not disclose the affected component or operation. The network attack is high complexity and needs no user interaction; Adobe's authentication field conflicts with its no-privileges assessment.
