CVE-2026-80172

critical · CVSS 9.8 · Dell Secure Connect Gateway

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Insufficient Verification of Data Authenticity vulnerability. An unauthenticated attacker with remote access could exploit this, leading to unauthorized access. This vulnerability is considered critical as an unauthenticated attacker can repeatedly reuse a captured request to generate ADMIN access and refresh tokens. Since there is no nonce validation or time limit on requests, the attack can be performed indefinitely. Dell recommends customers to upgrade at the earliest opportunity

CVE-2026-85103

critical · CVSS 9.8 · Check Point Quantum Security Gateway

CVE-2026-87654

critical · CVSS 9.6 · Google Chrome

Buffer overflow in ANGLE in Google Chrome on on Windows prior to 153.0.8010.36 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High)

CVE-2026-87874

high · CVSS 8.1 · Ansible community.general

A flaw was found in the memcached cache plugin of the community.general Ansible collection. Although its documentation states that records are stored in JSON format, the plugin performs no explicit serialization and relies on python-memcached, which pickles values on write and unpickles them on read. Because memcached is unauthenticated and cache keys are predictable, an attacker able to reach a network-exposed or shared memcached instance can write a crafted pickle payload that is deserialized and executed on the Ansible controller when the poisoned fact cache is next read, leading to remote code execution.

CVE-2026-87911

critical · CVSS 9.6 · Amazon postgres-mcp-server

An OS command injection weakness in the read-only enforcement of the SQL validation component in Amazon awslabs postgres-mcp-server before 1.1.7 might allow an unauthenticated actor to execute operating system commands on the host of a self-managed PostgreSQL server by placing a crafted COPY ... TO PROGRAM statement into content that is processed when an authenticated user interacts with the MCP server in its default read-only mode. To remediate this issue, users should upgrade to version 1.1.7 or later.
