CVE-2026-21293: SSRF in Adobe Commerce

The SSRF vulnerability in Adobe Commerce allows an attacker, possessing elevated privileges, to craft malicious requests that the server will execute. This can lead to several severe consequences. An attacker could potentially access internal resources that are not normally exposed to the internet, such as administrative panels, databases, or other sensitive systems. They might also be able to interact with other services within the internal network, potentially leading to lateral movement and a broader compromise. The lack of user interaction required for exploitation significantly increases the risk, as an attacker can initiate the attack without any user action on the target system.

The primary mitigation for CVE-2026-21293 is to upgrade Adobe Commerce to a version that includes the fix. Adobe has released patches to address this vulnerability. If immediate upgrading is not possible due to compatibility issues or other constraints, consider implementing temporary workarounds. These might include restricting outbound network access for the Adobe Commerce application, implementing strict input validation to prevent malicious URLs, and configuring a Web Application Firewall (WAF) to filter out suspicious requests. Regularly review and update your WAF rules to ensure they are effective against new attack patterns. After upgrading, confirm the fix by attempting to trigger the SSRF vulnerability with a known malicious URL and verifying that the request is blocked.
