WordPress to Automatically Block High-Risk Plugin Updates Before Distribution
WordPress is launching an automated security check for every new plugin release before it is distributed through the WordPress.org API. High-risk updates will be blocked automatically, preventing millions of sites from installing problematic code by clicking "Update."
Previously, the WordPress team reviewed new plugins only at the initial submission stage. Subsequent versions were released without mandatory security screening, allowing a previously safe plugin to later introduce vulnerabilities, backdoors, or changes in ownership with malicious intent.
Under the Protect The Shire initiative, every release now faces a mandatory six-hour delay. During this period, multiple AI models together with Jetpack Scan analyze the code changes. Their findings are combined into a final risk rating.
If the rating is high, the update is excluded from automatic installation. Developers receive an email detailing the detected issues. The mechanism already demonstrated its value before full deployment: on 28 July it identified a backdoor in an unnamed plugin with approximately 20,000 active installations. The release was still in the waiting period and never reached sites. Within 26 minutes of a Wordfence notification, the plugin was closed for downloads.
A high risk score does not automatically imply malicious intent. The system treats both deliberately inserted malware and accidental dangerous errors with equal seriousness. Developers are invited to review the findings, fix the code, and release a new version. If the new version passes the threshold, it proceeds to distribution. Results can be appealed, but WordPress notes that correcting the release is typically faster than awaiting manual review.

Malicious Code Injected into LiteLLM Open Source AI Package via Supply Chain Attack
The open-source generative AI tool LiteLLM had malicious code inserted into its official distribution packages, enabling credential theft and remote code execution. The compromise affected version 1.107.0 released on October 21, 2026, and was delivered through legitimate channels in a classic software supply chain attack. Seven malicious wheel files were uploaded to PyPI, while official container images on Docker Hub and GitHub Container Registry were also tainted. Security firm JFrog discovered that the malware steals a wide range of secrets including cloud credentials, SSH private keys, browser-stored passwords, development tokens, and AI service API keys from LiteLLM's database. The code also supports execution of externally fetched payloads and abuses Python's startup mechanisms to run even when the application itself is not loaded. This marks the second supply chain incident involving the project in 2026, following a separate event in March.
GhostAction Campaign Compromises 790 GitHub Repositories via Malicious Workflows
Researchers from OpenSourceMalware have identified 790 publicly accessible GitHub repositories containing malicious workflows planted by the GhostAction campaign as of October 9. The campaign abuses trusted maintainer accounts to inject workflows that automatically exfiltrate secrets including AWS access keys and tokens for GitHub, GitLab, Google, Slack, SendGrid, OpenAI, Anthropic, and OpenRouter. Earlier counts by GitGuardian recorded 772 repositories between August 31 and September 30, though the datasets differ and are not cumulative. A separate wave on October 8 impacted 346 repositories linked to two maintainer accounts, including a project belonging to Uber. The malicious workflow runs on code pushes or manual triggers, scans repository files and full Git history for credentials, and sends findings in plaintext to attacker infrastructure. Removing the workflow file does not mitigate exposure, as successful executions already leak credentials and old commits may still contain secrets.
SberTech Launches Platform V Orchestrator for Security Services to Scan Software Before Corporate Deployment
SberTech has announced the launch of a new direction focused on analyzing the security of software prior to its integration into corporate infrastructures. The initiative is built around the company's own Laboratory for Software Verification and the technological platform Platform V Orchestrator for Security Services. This platform combines components for working with both built-in and external analysis tools, enabling checks of digital artifacts, control over software composition and changes, and detection of vulnerabilities, hidden threats, and defects in source code and repositories. SberTech aims to replace fragmented checks and manual result processing with a single managed process, allowing scaled verification without proportional team growth. The move responds to the adoption of hundreds of products from various vendors, widespread use of open-source components, and rising attacks on software supply chains. Primary customers include banks, industrial enterprises, telecom operators, energy companies, and the public sector. The solution is offered as a standalone product that supports on-premises deployment and operation in isolated environments such as private clouds and dedicated data processing contours.
NEC Subcontractor Suffers Cyber Attack Leading to Customer System Disruptions and Personal Data Leak
NEC disclosed that a subcontractor handling system development and maintenance was compromised in a cyber attack during late September 2026. Attackers stole legitimate account credentials and used them to access multiple customer environments from the subcontractor's systems. The intrusion resulted in server files being encrypted, rendering customer systems inoperable. Additional files containing personal information and system details were exfiltrated from a shared cloud storage platform used for coordination between NEC, the subcontractor, and customers. Affected customers have been notified individually, with further details on compromised personal data to be provided as they become available. The incident highlights risks associated with third-party vendor access in IT supply chains.
