wp2shell is the name given to an unauthenticated remote code execution attack against WordPress core. It is not a single bug. It is a chain of two separately tracked flaws that, combined, let an anonymous attacker run code on a default WordPress installation with no plugins, no valid account, and no user interaction. The first flaw, CVE-2026-63030, is a REST API batch-route confusion issue in WP_REST_Server::serve_batch_request_v1().

CVE-2026-56164 is a privilege escalation vulnerability in on-premises Microsoft SharePoint Server, caused by a missing authentication check on a critical function (CWE-306). An unauthenticated attacker can exploit it over a network, with no credentials and no user interaction required. The vulnerability carries a CVSS v3.1 base score of 5.3 (Medium), and Microsoft rates it Moderate.

CVE-2026-56291 is an unauthenticated arbitrary file upload vulnerability in Balbooa Forms, a commercial drag-and-drop form builder for Joomla installed as the com_baforms component. The flaw is classified as CWE-434, unrestricted upload of a file with a dangerous type. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical). It has also been assigned a CVSS v4.0 base score of 10.0 (Critical), with an exploitation maturity of “attacked.”

CVE-2026-40138 and CVE-2026-40139 are two pre-authentication vulnerabilities in the authentication subsystem of BeyondTrust Remote Support (RS) and Privileged Remote Access (PRA), stemming from improper validation and processing of authentication data. Both carry a CVSS v3.1 base score of 9.2 (Critical).

CVE-2026-57517 is a blind SQL injection vulnerability in Control Web Panel (CWP), caused by insufficient sanitization of the userRes POST parameter submitted to the panel’s user endpoint before the value is used to build a SQL query. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical).

CVE-2026-55957 is a missing critical step in authentication in Apache Tomcat, present when the JNDIRealm is configured to authenticate binds using GSSAPI. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical), based on network attack vector, low attack complexity, no privileges required, and no user interaction.

Over the past months, I’ve noticed a shift in customer conversations. Coverage, prioritization, emerging threats — those questions have given way to exposed MCP servers, unmanaged AI chatbots, and risks that don’t show up as CVEs. Mythos comes up in every other call. The calculus changed. AI now writes a quarter of production code, with twice as many vulnerabilities. The exploitation window collapsed from days to hours.

CVE-2026-27577 is a code injection flaw in n8n, an open-source workflow automation platform, that lets an authenticated user with permission to create or modify workflows run system commands on the host through crafted workflow expressions. The vulnerability carries a CVSS base score of 9.4 (Critical). Exploitation requires authentication, but only the level of access needed to build or edit a workflow, which is a routine privilege for many users of the platform.

CVE-2026-53721 is a route-rule middleware bypass in Nuxt, the open-source web development framework for Vue.js. It stems from a case-sensitivity mismatch between vue-router and the framework’s routeRules matcher, which lets an attacker reach a protected route by varying the casing of the request path. The vulnerability carries a CVSS v4.0 base score of 8.8 (High). Exploitation is pre-authentication and requires no user interaction.

CVE-2026-49975 is a memory exhaustion vulnerability in the mod_http2 module of Apache HTTP Server that allows a remote attacker to cause a denial of service through maliciously crafted HTTP/2 requests. It is classified as CWE-789, Memory Allocation with Excessive Size Value, and was publicly disclosed as part of an attack technique nicknamed the “HTTP/2 Bomb.” The vulnerability carries a CVSS v3.1 base score of 7.5 (High).
