Adobe Commerce | Server-Side Request Forgery (SSRF) (CWE-918)

The SSRF vulnerability in Adobe Commerce allows an attacker to craft malicious requests that the server will execute on its behalf. This can lead to several severe consequences. An attacker could potentially access internal services and data that are not publicly exposed, such as administrative panels or sensitive configuration files. They might also be able to scan internal networks for other vulnerable systems, facilitating lateral movement. The blast radius extends to any resources accessible by the Adobe Commerce server, potentially including cloud storage, databases, and other internal applications. While the description doesn't explicitly mention it, SSRF vulnerabilities can sometimes be leveraged for remote code execution if the server is configured to process data from external sources in an unsafe manner.

Organizations heavily reliant on Adobe Commerce for their e-commerce operations are at significant risk. This includes businesses using older, unsupported versions of Adobe Commerce, as well as those with complex configurations or custom extensions that may exacerbate the vulnerability. Shared hosting environments where multiple tenants share the same server infrastructure are also particularly vulnerable.

The primary mitigation for CVE-2026-21293 is to upgrade Adobe Commerce to a patched version. Adobe has not specified a fixed version in the provided data, so consult the official Adobe Security Bulletin for the latest recommended version. If upgrading immediately is not feasible, consider implementing temporary workarounds. These may include restricting outbound network access from the Adobe Commerce server using a Web Application Firewall (WAF) or proxy server. Configure the WAF to block requests to known malicious domains or IP addresses. Review and tighten access controls to internal resources to limit the potential impact of a successful SSRF attack. Regularly monitor access logs for suspicious outbound requests.
