A critical remote code execution vulnerability has been identified in Langflow. The vulnerability was first reported to the vendor in mid-2025 and disclosed publicly as a zero-day in January 2026. Exploitation attempts rose sharply in late August 2026, moving from isolated probing to continuous, multi-source scanning within days.

CVE-2026-55040, a critical SharePoint authentication bypass, is now being actively exploited. A proof-of-concept went public on August 11. Within 24 hours, threat intelligence firm Defused confirmed exploitation attempts against its SharePoint honeypots using that same PoC. Over 8,500 SharePoint servers remain reachable from the open internet, putting unpatched instances at immediate risk.

Hosting environments run on a basic assumption: an account with limited permissions should stay limited. CVE-2026-58048 breaks that assumption inside cPanel & WHM. Any authenticated account with MySQL or MariaDB feature access, including a standard low-privilege hosting account, can now escalate to root-level database privileges through a database rename operation. A public proof-of-concept already exists, which means the barrier to exploitation is low and the window to act is short.

For the last several months, we have run AI agents against real production applications across industries. Two questions drove the work: what does AI-powered vulnerability analysis and pentesting surface at scale, and what does protection have to look like to keep pace. The vulnerability discovery side confirmed what Mythos made impossible to ignore.

AI assistants are quietly becoming one of Microsoft’s largest attack surfaces. In its July 2026 advisory, Microsoft patched a command injection vulnerability in Copilot. Crafted prompts can trigger unintended actions through this flaw. The advisory also included a critical SSRF vulnerability in Entra’s identity provisioning service. It carries the among the highest severity score in the entire release. Both point to the same shift.

Oracle released its July 2026 Critical Patch Update (CPU) on July 21, delivering 1,449 security fixes across 1,235 unique CVEs, the largest CPU in the company’s history. The release spans 32 product families, with the heaviest concentration in Oracle E-Business Suite, Oracle Fusion Middleware, Oracle Communications, and PeopleSoft. Nine of these CVEs received a perfect CVSS 10.0 score.

Microsoft released patches for over 570 vulnerabilities in its July 2026 Patch Tuesday, the largest security update in the company’s history, including two zero-days already under active exploitation. Among them, one stands out for how it is being exploited right now: an unauthenticated vulnerability in SharePoint Server that allows an unauthenticated attacker to elevate privileges to Farm Administrator.

ServiceNow AI Platform (the enterprise PaaS formerly branded in the Now Platform) contains a critical, unauthenticated remote code execution vulnerability tracked as CVE-2026-6875. The vulnerability allows a remote attacker to escape ServiceNow’s JavaScript execution sandbox. No credentials or user interaction are required, and the attacker achieves full code execution on the underlying instance.

A newly disclosed WordPress exploit chain, nicknamed “WP2Shell,” lets unauthenticated attackers achieve remote code execution (RCE) on any WordPress Core installation, no plugins required. Disclosed on July 17, 2026, the chain combines two vulnerabilities: CVE-2026-60137 (SQL injection) and CVE-2026-63030 (REST API batch-route confusion).

Enterprises running Adobe ColdFusion often carry legacy development features forward long after the original use case is gone. Remote Development Services (RDS) is a good example: a convenience feature that lets an IDE talk to a live ColdFusion server, left switched on from an old dev workflow years after anyone remembers why.
