SAP Commerce Cloud CVE-2026

Attackers actively exploit unauthenticated RCE CVE-2026-58231 (CVSS 10.0) in SAP Commerce Cloud days after patch release.

CVE-2026-58231, a maximum-severity flaw in SAP Commerce Cloud (CVSS 10.0), allows unauthenticated attackers to abuse a default authentication client and bypass insufficient validation, achieving arbitrary code execution and compromise of internal components. Defused Cyber researchers observed exploitation attempts against honeypots only three days after SAP released the patch. The flaw had no public PoC and was not previously known to be exploited. The attackers are unknown, though past critical SAP flaws have been exploited by China-linked groups UNC5221 and UNC5174 and ransomware gangs.

Attackers Exploit VMware vCenter Vulnerability to Gain Persistent Remote Access

Attackers actively exploit critical VMware vCenter flaw CVE-2026-59310, installing reverse_ssh backdoors on 361 hosts across 47 countries.

QUIRSO observed active exploitation of CVE-2026-59310 (CVSS 9.8), a directory-traversal flaw in VMware vCenter allowing arbitrary code execution, patched by Broadcom in late July. Attack chains deploy a malicious cron job running the open-source reverse_ssh tool for persistence, with compromised systems phoning home starting August 3, five days after disclosure. Forensics show 361 unique victim IPs in 47 countries, mostly Germany, the U.S., Turkey, Iran, and France, with the actor suspected to be an APT. Separately, Defused Cyber reports rising scanning indicative of exploitation of related CVE-2026-59309, an unauthenticated auth bypass in vmdir.

Unauthenticated Path Traversal RCE in Broadcom VMware vCenter Server Syslog
CVE-2026-59310 is a directory traversal (CWE-22) vulnerability in the Syslog server component of VMware vCenter Server, rated critical at CVSS 9.8. It can be triggered over the network without authentication or user interaction, allowing a malicious actor with network access to vCenter to achieve arbitrary code execution. An attacker who exploits it gains code execution on the vCenter appliance, and reported campaigns show it has been used to establish persistent remote access and, by a suspected China-nexus actor, to deploy Babuk ransomware. Any organization running an affected version of vCenter Server is exposed, especially where the management interface is reachable from the internet; the available data does not specify affected version ranges. Exploitation is confirmed in the wild: CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-18, it was reportedly exploited just five days after disclosure, and EPSS estimates a 45.9% probability of exploitation within 30 days (99th percentile).
