Adobe Commerce and Magento file upload flaw exploited to run code via crafted links
An actively exploited unrestricted file upload flaw in Adobe Commerce, Magento, Commerce B2B and I/O Events can lead to code execution after a victim visits a crafted URL. Apply Adobe's APSB26-73 guidance immediately. CISA's remediation deadline is 2026-11-10.
In plain terms
Adobe Commerce and Magento are widely used platforms for running online shops. This vulnerability is in the way the software handles uploaded files. It does not properly stop dangerous file types, such as files the server could treat as programs, from being uploaded. An "unrestricted file upload" flaw means an attacker may be able to place such a file where the system will later run it.
According to Adobe's description, abuse of this flaw could let an attacker run code with the permissions of the affected user. It could also give the attacker control over that user's account or session. The attack needs a victim to click a malicious link or visit a compromised page. CISA has confirmed that the flaw is being exploited. Anyone running an affected Adobe Commerce or Magento store should treat it as urgent.
