Mythos Didn't Break Your Security Program. Your Exposure Window Could.

The industry spent the initial months after Anthropic's April 7 Mythos reveal focused on volume. How many new CVEs would Mythos add to an already overloaded pipeline? How quickly would the flood of AI-driven discovery overwhelm triage capabilities? How long would it take adversaries to weaponize Mythos findings at scale? Those questions were and remain valid. Yet they all stop short of

New 7-Zip Vulnerability Could Let Crafted XZ Archives Run Code During Extraction

Opening a crafted XZ archive in 7-Zip could let an attacker run code on the machine. The flaw, CVE-2026-14266, is a heap-based buffer overflow in how the archiver processes XZ chunked data, and Trend Micro's Zero Day Initiative (ZDI) detailed it on July 15. A fix shipped on June 25 in 7-Zip 26.02. The overflow lets an attacker "execute code in the context of the current process," per the

New wp2shell WordPress Core Flaw Lets Unauthenticated Attackers Run Code

An anonymous HTTP request can run code on a WordPress site. The bug is in core, so a bare install with zero plugins is exploitable. Every 6.9 and 7.0 site was in range until Friday, when WordPress shipped 6.9.5 and 7.0.2 and enabled what it calls forced updates through its auto-update system. Adam Kues at Assetnote, Searchlight Cyber's attack surface management arm, found the flaw and reported

OpenSSL HollowByte Flaw Could Freeze Server Memory with 11-Byte TLS Requests

Eleven bytes will make an unpatched OpenSSL server set aside up to 131 KB of memory for a message that never arrives. On the glibc systems Okta tested, that memory is gone until the process restarts. OpenSSL shipped the HollowByte fix in June with no CVE, no advisory, and no changelog entry pointing at it. Okta's Red Team, which reported the denial-of-service bug and named it, published the

New NadMesh Botnet Hunts Exposed AI Services for Cloud Keys and Kubernetes Tokens

A Go botnet called NadMesh turned up in early July hunting exposed AI services, and the operator's own dashboard claims 3,811 unique AWS keys. A Shodan harvester keeps the scan queue stocked with ComfyUI, Ollama, n8n, Open WebUI, Langflow, and Gradio: the image generators, local model runners, and workflow builders that teams stand up fast and firewall late. The intel feed behind that counter
