U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds BerriAI LiteLLM and Check Point Security Gateway flaws to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added BerriAI LiteLLM and Check Point Security Gateway flaws to its Known Exploited Vulnerabilities (KEV) catalog.

The two flaws added to the catalog are:

CVE-2026-42271 (CVSS score ver.4.0 of 8.7) BerriAI LiteLLM Command Injection Vulnerability
CVE-2026-50751 (CVSS score of 9.3) Check Point Security Gateway Improper Authentication Vulnerability

The CVE-2026-42271 flaw is a privilege escalation and remote code execution vulnerability in LiteLLM affecting versions 1.74.2 through 1.83.6. The issue stems from two MCP server testing endpoints that allowed authenticated users to supply custom server configurations, including commands and environment variables. Because the application executed these commands as subprocesses on the host system without enforcing role-based access controls, even low-privileged users with a valid API key could run arbitrary commands on the server. The vulnerability was fixed in LiteLLM version 1.83.7.

The second flaw added to the catalog, tracked as CVE-2026-50751, is a critical authentication bypass flaw in Check Point VPN, Mobile Access, and Spark Firewalls. The vulnerability affects the deprecated IKEv1 key exchange process and allows unauthenticated attackers to establish remote VPN connections without needing valid credentials.

Check Point warns that CVE-2026-50751 is being actively exploited. Attacks have been observed since May 2026, with activity increasing in early June. The campaign appears limited, affecting several dozen organizations, and at least one incident has been linked, with medium confidence, to a Qilin ransomware affiliate.

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix the Check Point Security Gateway vulnerability by June 11, 2026, and the BerriAI LiteLLM flaw by June 22, 2026.
