The Apache Software Foundation has released a critical security update for Apache HTTP Server, patching five vulnerabilities, including a dangerous double-free flaw capable of enabling Remote Code Execution (RCE) in version 2.4.67, released on May 4, 2026.

Welcome back to another watchTowr Labs blog. Brace yourselves, this is one of our most astounding discoveries.

Introduction Hello, I’m RyotaK (@ryotkak ), a security engineer at Flatt Security Inc. A few days ago, I was upgrading my home lab network, and I decided to upgrade the OpenWrt on my router.1 After accessing the LuCI, which is the web interface of OpenWrt, I noticed that there is a section called Attended Sysupgrade, so I tried to upgrade the firmware using it. After reading the description, I found that it states it builds new firmware using an online service.

While preparing for my Black Hat and DEF CON talks in July of this year, I found the most impactful Entra ID vulnerability that I will probably ever find. One that could have allowed me to compromise every Entra ID tenant in the world (except probably those in national cloud deployments). If you are an Entra ID admin reading this, yes that means complete access to your tenant. The vulnerability consisted of two components: undocumented impersonation tokens that Microsoft uses in their backend for service-to-service (S2S) communication, called “Actor tokens”, and a critical vulnerability in the (legacy) Azure AD Graph API that did not properly validate the originating tenant, allowing these tokens to be used for cross-tenant access.

CISA says the U.S. government has extended MITRE's funding to ensure no continuity issues with the critical Common Vulnerabilities and Exposures (CVE) program.

Introduction: when the trust model can’t be trusted Secrets vaults are the backbone of digital infrastructure. They store the credentials, tokens, and certificates that govern access to systems, services, APIs, and data. They’re not just a part of the trust model, they are the trust model. In other words, if your vault is compromised, your […]

We started developing our vulnerability management platform (VMP) at Spotify in Q2, 2020, and now that we’ve implemented it and use the system in our day-to-day work, we wanted to take a moment to share our journey to help reduce security risks in an efficient and scalable manner.
