SAP Commerce Cloud CVE-2026-58231 Targeted in Exploitation Attempts Days After Patch

A maximum-severity (CVSS 10.0) unauthenticated RCE flaw in SAP Commerce Cloud, CVE-2026-58231, is under active exploitation days after patching.

CVE-2026-58231, rated 10.0 on CVSS, stems from insufficient authorization checks and input validation in SAP Commerce Cloud, enabling unauthenticated arbitrary code execution. Defused Cyber's honeypots detected exploitation attempts three days after the patch, and KEVIntel independently confirmed two attempts on August 14 from a US IP address. Onapsis urges customers to patch and rebuild, with an IP Filter Set offered as a temporary workaround. No actor attribution yet, though prior SAP NetWeaver flaw CVE-2025-31324 was exploited by China-nexus and criminal groups.

VU#212479: Sentry Seer vulnerability allows attacker-controlled input to be executed in a privileged environment

CERT/CC details CVE-2026-90999: attacker-controlled Sentry telemetry can steer the Seer coding agent into executing attacker code with repository access.

CERT/CC published VU#212479 for CVE-2026-90999 in Sentry Seer: attacker-submitted events through public DSN endpoints flow into Seer's root-cause analysis, which is embedded directly into the coding agent's initial prompt. In the documented chain, the privileged coding agent downloads and executes an attacker-controlled package before any human review, yielding arbitrary code execution with access to connected source repositories. No vendor patch is available yet; mitigations include disabling automated remediation, restricting coding-agent package installation, and filtering telemetry before Seer analysis.

Adobe Commerce max-severity bug comes under active attack

Attackers are actively exploiting CVE-2026-75650 (CVSS 10.0), an unauthenticated RCE zero-day in Adobe Commerce/Magento, deploying a Rust backdoor on e-commerce servers.

Sansec identified active exploitation of a CVSS 10.0 zero-day (CVE-2026-75650) in Adobe Commerce and Magento Open Source versions 2.4.4 through 2.4.9, dubbed StyleSmuggler.

Critical unauthenticated RCE zero-day CVE-2026-75650 (StyleSmuggler) in Adobe Commerce and Magento is actively exploited; Adobe shipped hotfix VULN-39341 on September 7.

CVE-2026-75650 is a CVSS 10.0 unauthenticated remote code execution flaw in Adobe Commerce 2.4.4-2.4.9, Adobe Commerce B2B 1.3.3-1.5.3, and Magento Open Source 2.4.6-2.4.9, exploited via malicious style properties that inject PHP code executed through a transactional email template. Active exploitation began September 4, 2026, three days before Adobe released Hotfix VULN-39341 (APSB26-146) on September 7, with multiple victim stores confirmed by Sansec and Disrex across at least two distinct campaigns. Attackers deploy a persistent implant at ~/.local/share/.gvfsd/gvfsd-user masquerading as kworker, fc-cache, or chronyd, sustained by a cron job, while a second operator dropped a PHP web shell in product image caches.
