Cybersecurity researchers have disclosed details of two now-patched security flaws in the n8n workflow automation platform, including two critical bugs that could result in arbitrary command execution. The vulnerabilities are listed below - CVE-2026-27577 (CVSS score: 9.4) - Expression sandbox escape leading to remote code execution (RCE) CVE-2026-27493 (CVSS score: 9.5) - Unauthenticated expression evaluation via n8n's Form nodes "CVE-2026-27577 is a sandbox escape in the expression compiler: a missing case in the AST rewriter lets process slip through untransformed, giving any authenticated expression full RCE," Pillar Security researcher Eilon Cohen, who discovered and reported the issues, said in a report shared with The Hacker News. The cybersecurity company described CVE-2026-27493 as a "double-evaluation bug" in n8n's Form nodes that could be abused for expression injection by taking advantage of the fact that the form endpoints are publi...

SAP has released security updates to address two critical security flaws that could be exploited to achieve arbitrary code execution on affected systems. The vulnerabilities in question listed below - CVE-2019-17571 (CVSS score: 9.8) - A code injection vulnerability in SAP Quotation Management Insurance application (FS-QUO) CVE-2026-27685 (CVSS score: 9.1) - An insecure deserialization vulnerability in SAP NetWeaver Enterprise Portal Administration "The application uses an outdated artifact of Apache Log4j 1.2.17 that is vulnerable to CVE-2019-17571," SAP security company Onapsis said . "It allows an unprivileged attacker to execute arbitrary code remotely on the server, causing high impact on confidentiality, integrity, and availability of the application." CVE-2026-27685, on the other hand, stems from missing or insufficient validation during the deserialization of uploaded content, which could allow an attacker to upload untrusted or malicious content...

Microsoft on Tuesday released patches for a set of 84 new security vulnerabilities affecting various software components, including two that have been listed as publicly known. Of these, eight are rated Critical, and 76 are rated Important in severity. Forty-six of the patched vulnerabilities relate to privilege escalation, followed by 18 remote code execution, 10 information disclosure, four spoofing, four denial-of-service, and two security feature bypass flaws. The fixes are in addition to 10 vulnerabilities that have been addressed in its Chromium-based Edge browser since the release of the February 2026 Patch Tuesday update . The two publicly disclosed zero-days are CVE-2026-26127 (CVSS score: 7.5), a denial-of-service vulnerability in .NET, and CVE-2026-21262 (CVSS score: 8.8), an elevation of privilege vulnerability in SQL Server. The vulnerability with the highest CVSS score in this month's update is a critical remote code execution flaw in the Microsoft Devices ...

Cybersecurity researchers are calling attention to a new campaign where threat actors are abusing FortiGate Next-Generation Firewall (NGFW) appliances as entry points to breach victim networks.  The activity involves the exploitation of recently disclosed security vulnerabilities or weak credentials to extract configuration files containing service account credentials and network topology information, SentinelOne said in a report published today. The security outfit said the campaign has singled out environments tied to healthcare, government, and managed service providers. "FortiGate network appliances have considerable access to the environments they were installed to protect," security researchers Alex Delamotte, Stephen Bromfield, Mary Braden Murphy, and Amey Patne said . "In many configurations, this includes service accounts which are connected to the authentication infrastructure, such as Active Directory (AD) and Lightweight Directory Access Protocol (LDAP)....

Cybersecurity researchers have disclosed nine cross-tenant vulnerabilities in Google Looker Studio that could have permitted attackers to run arbitrary SQL queries on victims' databases and exfiltrate sensitive data within organizations' Google Cloud environments. The shortcomings have been collectively named LeakyLooker by Tenable. There is no evidence that the vulnerabilities were exploited in the wild. Following responsible disclosure in June 2025, the issues have been addressed by Google. The list of security flaws is as follows - Cross Tenant Unauthorized Access - Zero-Click SQL Injection on Database Connectors Cross Tenant Unauthorized Access - Zero-Click SQL Injection Through Stored Credentials Cross Tenant SQL Injection on BigQuery Through Native Functions Cross-Tenant Data Sources Leak With Hyperlinks Cross Tenant SQL injection on Spanner and BigQuery Through Custom Queries on a Victim’s Data Source Cross Tenant SQL Injection on BigQuery and Spanner Through...
