A critical SAP Commerce Cloud vulnerability, tracked as CVE-2026-58231 (CVSS score of 10.0), is under active exploitation just days after SAP released a patch. The flaw stems from insufficient authorization checks and input validation.
“SAP Commerce Cloud allows an unauthenticated attacker to abuse a default authentication client and submit specially crafted input to certain functions lacking sufficient validation.” reads the advisory. “Successful exploitation could enable arbitrary code execution and compromise internal components, resulting in high impact on confidentiality, integrity, and availability of the application.”
An unauthenticated attacker can abuse a default authentication client and send crafted input to vulnerable functions, potentially achieving arbitrary code execution and compromising internal components.
Researchers at Defused Cyber observed exploitation attempts against honeypots only three days after the patch was released. The researchers pointed out that this vulnerability has no public PoC and had not been known to be exploited prior to their discovery.
The attackers behind the current exploitation remain unknown. However, previous critical SAP flaws have been exploited by China-linked APT groups, including UNC5221 and UNC5174, and ransomware gangs.
