CVE-2026-63030

CyberXero Deploys 51 AI Agents to Scan 4708 Targets and Implant 32 WebShells in 61 Seconds

Russian-speaking initial access broker CyberXero integrated Anthropic's Claude Code and the open-source PentAGI autonomous penetration agent into its attack pipeline, creating a cluster of 51 specialized AI agents. The group ran two parallel operations: one automated campaign targeting vulnerable WordPress and e-commerce sites worldwide using known exploits including CVE-2026-63030, CVE-2026-60137 and CVE-2026-4815, and a second, more targeted campaign against Ukrainian energy and critical infrastructure. In one recorded execution the AI cluster scanned 4708 public-facing hosts, compromised 429 WordPress administrative panels and dropped 32 WebShells within a 61-second window. Attackers bypassed model safety guardrails by resetting sessions and reframing requests as authorized penetration tests of their own infrastructure. The operation relied on an eight-node architecture that included a Linux workstation, configuration server, payload staging server and public Redis instances, two of which belonged to Chinese organizations. SOCRadar warns that session-level controls alone are insufficient and recommends enforcing system-level boundaries, minimal privileges and strict egress filtering for any AI agents.

Critical wp2shell Vulnerability Chain Exploited in WordPress for Unauthenticated Remote Code Execution and Webshell Deployment

A critical vulnerability chain dubbed wp2shell is being actively exploited against WordPress Core installations, enabling unauthenticated remote code execution and the installation of persistent webshells. The flaws affect versions 7.0.x prior to 7.0.2, 6.9.x prior to 6.9.5, and the 6.8 branch before 6.8.6, with patches now available. Attackers chain CVE-2026-63030 and CVE-2026-60137 through the WordPress REST API batch processing endpoint and an SQL injection in WP_Query via the author__not_in parameter. Observed campaigns involve mass scanning, user enumeration, attempts to read wp-config.php, and deployment of PHP webshells in wp-content/cache that return fake 404 responses. Administrators are urged to update immediately, audit logs for anomalous REST API requests, inspect for unauthorized admin accounts or plugins, and rotate credentials if wp-config.php exposure is suspected.

WordPress Releases Security Update Fixing Two Vulnerabilities That Chain to Remote Code Execution

The WordPress development team has issued version 7.0.2 along with other security releases on July 17, 2026, addressing two critical vulnerabilities identified as CVE-2026-63030 and CVE-2026-60137. When combined, these flaws enable remote attackers to execute arbitrary code on affected installations. CVE-2026-60137 stems from insufficient input validation in certain functions, potentially allowing SQL injection when processing untrusted data from plugins or themes. CVE-2026-63030 involves route interpretation confusion in the REST API batch endpoint, which can be leveraged alongside the SQL injection issue to achieve code execution. The vulnerabilities impact WordPress 6.8 and later branches, although chained attacks are not possible on the 6.8 series. Administrators are urged to apply the updates immediately to mitigate the risks.
