A single request should not be able to do this much. But this week, small inputs led to code execution, memory loss, stolen keys, and disabled security tools.

The paths were often simple: exposed systems, weak checks, old drivers, fake prompts, and public code used for malware delivery. Some bugs were new. Others were already being used before defenders had time to patch.

Here is the full recap of what broke, what was exploited, and what needs attention now.

New wp2shell WordPress Core Flaw Lets Unauthenticated Attackers Run Code - Searchlight Cyber disclosed a pre-authenticated remote code execution vulnerability in WordPress Core that can be exploited anonymously on a standard WordPress installation, without requiring any plugins or other special conditions. It is a combination of CVE-2026-63030 (REST API batch-route confusion) and CVE-2026-60137 (SQL injection in WordPress core) that can be chained to turn an anonymous request into code execution. watchTowr said it's already seeing proof-of-concept (PoC) exploits in circulation and that it's beginning to see the first signs of in-the-wild exploitation. "This is going to hurt," watchTowr CEO Benjamin Harris said. "WordPress runs on hundreds of millions of websites globally. Some of those will be auto-patched by their hosting providers, but plenty will not, and that is where the damage will be done. Our advice is simple: patch as fast as you possibly can, and do not stop there. Put the controls and investigations in place to determine whether an attacker got there first and to detect and remove any backdoors that may already have been dropped before you patched." The cybersecurity company said it's the latest example of vulnerabilities being surfaced by AI-assisted tooling and how the technology is being abused by attackers to weaponize them.
