Cybersecurity researchers at Wiz have disclosed a new GitHub Actions workflow injection vulnerability in Snowflake's public  snowflakedb/snowflake-connector-net repository that it said could be exploited through a crafted GitHub issue to execute commands in a workflow containing internal Jira credentials. The issue was present in  .github/workflows/jira_issue.yml , which ran when a public issue was opened and exposed JIRA_BASE_URL, JIRA_USER_EMAIL, and JIRA_API_TOKEN to the same workflow step. The weakness was confined to the repository's CI/CD automation, with no affected Snowflake Connector for .NET release identified. The workflow inserted attacker-controlled issue title and body values directly into a shell run: block. It also checked github.event.pull_request.user.login even though the event was an issue, meaning the referenced pull request property did not exist. GitHub says , "If you attempt to dereference a nonexistent pr...

A critical security flaw has been disclosed in Forminator Forms, a WordPress plugin with more than 600,000 active installations, that could be exploited to achieve arbitrary code execution on susceptible sites. The vulnerability, tracked as CVE-2026-15748 , is rated 9.8 out of 10.0 on the CVSS scoring system. It was discovered and reported by a security researcher who goes by the online alias "daroo." "This vulnerability makes it possible for unauthenticated attackers to upload arbitrary files, including executable PHP files, to a vulnerable site, which can lead to remote code execution and complete site compromise," Wordfence said in a report published today. That said, a key prerequisite for successful exploitation is that the sites must have a form containing both a File Upload field and a Select field. The vulnerability impacts all versions of the plugin before and including 1.56.1. It has been addressed in version 1.56.2 released on July 31, 2026. Pe...

The expensive attacks are not always the clever ones. This week had plenty of proof. Exposed services got hit, old bugs found fresh use, browser sessions became attack paths, and supply-chain problems kept spreading farther than the original compromise. A lot of it came down to access that was already there and defenses that assumed nobody would look too closely. So, nothing magical. Just a lot of small openings turning into bigger problems. Here’s what stood out. ⚡ Threat of the Week Suspected China APT Behind Exploitation of New VMware Flaw — A suspected China-nexus APT is assessed to be behind the exploitation of a newly patched security flaw in VMware vCenter. The attacks involve the exploitation of CVE-2026-59310 (CVSS score: 9.8), a severe directory-traversal vulnerability in the VMware vCenter server that could be weaponized by a malicious actor to execute arbitrary code. In at least one compromised instance, the attacks led to the deployment of a backdoor and. a rever...

MCP servers can expose enterprise secrets through plaintext configuration files, over-permissioned access and prompt injection, often before security teams even know the server is running. As more organizations adopt AI agents into their systems, that exposure can silently become a major gap in MCP server security. The Model Context Protocol (MCP) allows AI agents to reach the tools and data, including internal documentation and cloud infrastructure, that form the foundation of enterprise systems. Behind that convenience, the MCP server connecting those tools and data to enterprise systems typically holds the keys to everything it touches: credentials, service account keys, API tokens and other secrets. Every organization should now question what secrets they are handing to AI and how well those secrets are protected once they reach an MCP server. What is Model Context Protocol (MCP)? Model Context Protocol (MCP) is an open standard, originally introduced by Anthropic, that allows...

Security researchers at SSD Secure Disclosure have published a two-stage exploit chain that achieves full Android kernel access on devices running Unisoc modem firmware through a VoLTE video call, with no fix from the chipset maker. The  advisory , published August 17, 2026, is the second stage of a chain that began in March 2026, when SSD disclosed  remote code execution  in the same firmware through a malformed SIP video call. Completing the full chain requires the attacker to control a private 4G cellular network and the victim to answer the incoming video call. "We have tried to reach out to the vendor through multiple channels (email and LinkedIn) but have not been able to receive any response," SSD Secure Disclosure said in its advisory. The March 2026 disclosure carried the same statement. The research was carried out by an independent security researcher using the handle 0x50594d. The privilege-escalation vulnerability is classified as CWE-1189, Improper ...
