CVE-2026-3854 is a command injection vulnerability in GitHub Enterprise Server. It lives in the git push pipeline. User-supplied push option values were not properly sanitized before being embedded in an internal service header. The header format used a delimiter that could also appear in user input. A crafted push option containing that delimiter let an attacker inject additional metadata fields. Downstream services treated those fields as trusted internal values.

CVE-2026-40372 is an elevation of privilege vulnerability in ASP.NET Core caused by improper verification of cryptographic signatures in the Data Protection library. The flaw sits in the HMAC validation routine of the managed authenticated encryptor, where a defective comparison lets an attacker submit a forged payload that the application accepts as legitimately signed. The vulnerability carries a CVSS v3.1 base score of 8.1 (Important), as assigned by Microsoft in the official advisory.

CVE-2026-29145 is an authentication bypass flaw in Apache Tomcat and Apache Tomcat Native affecting the CLIENT_CERT authentication path. When OCSP soft-fail is disabled, certain code paths fail to treat an OCSP check failure as a hard authentication failure, allowing a connecting client to reach protected resources without presenting a valid, revocation-checked certificate.

CVE-2026-23869 is a denial of service vulnerability in React Server Components, caused by improper handling of cyclic data structures during deserialization of incoming HTTP requests. The vulnerability resides in the React Flight protocol's server-side reply handling, specifically in the createMap, createSet, and extractIterator functions within ReactFlightReplyServer.js. The vulnerability carries a CVSS v3.1 base score of 7.5 (High). Exploitation requires no authentication and no user interaction.

A few weeks ago the world was exposed to Mythos, Anthropic's new frontier model and the Project Glasswing announcement that came with it. The reaction across the industry was immediate. Cybersecurity stocks fell sharply. The Treasury Secretary convened an emergency meeting with major bank CEOs. 250 CISOs produced a response playbook over a single weekend. That is not a typical announcement or a PR "leak". That is a reckoning. Then, about a week later, I came across MOAK.

CVE-2026-20093 is an authentication bypass vulnerability in the change password functionality of Cisco Integrated Management Controller (IMC), caused by improper input validation (CWE-20) in how the IMC XML API processes password modification requests. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical). Exploitation is fully pre-authentication and requires no privileges and no user interaction.

CVE-2026-27876 is an arbitrary file write vulnerability in Grafana's sqlExpressions feature that can be chained with a Grafana Enterprise plugin to achieve remote code execution (RCE) on the underlying host. The flaw exists because Grafana's SQL expressions feature permits writing arbitrary files to the server filesystem. An attacker can exploit this to overwrite a Sqlyze driver or write an AWS data source configuration file, ultimately obtaining an SSH connection to the Grafana host.

On March 31, 2026, two malicious versions of axios were published to npm, , using credentials stolen from a lead axios maintainer. The attacker injected a hidden dependency into both releases that drops a remote access trojan (RAT) on any machine that ran npm install during the exposure window. No CVE identifier has been assigned at the time of writing. The malicious dependency executes automatically at install time via a postinstall hook, without any action by the developer.

CVE-2025-53521 is an unauthenticated remote code execution vulnerability in F5's BIG-IP Access Policy Manager (APM). The flaw exists in the apmd process, the daemon responsible for processing live access policy traffic, and is triggered when a BIG-IP APM access policy is configured on a virtual server and the system receives specific malicious traffic. No credentials are required to exploit it. The vulnerability carries a CVSS score of 9.8 and a CVSS score of 9.3.
