CVE-2026-16732

A flaw was found in fastify. When configured with a numeric trustProxy value, an attacker who can directly access the Fastify origin, bypassing the front-facing proxy, can spoof forwarded request fields. This vulnerability allows for host injection in generated URLs, bypasses HTTPS enforcement, a...

CVE-2026-16732

fastify is a fast and low overhead web framework for Node.js. Impact: the fix for CVE-2026-3635 added a guard on the forwarded-header reads used to derive the request host, protocol, hostname, ip, and ips values, checking the connecting address. That guard closes the IP, CIDR, and custom-function...

CVE-2026-16732

Fastify 5.8.3–5.12.0 remains vulnerable to X-Forwarded-* spoofing when trustProxy is set numerically (e.g., 1), because the CVE-2026-3635 guard predicate ignores the connecting address. This enables host injection, HTTPS-enforcement bypass, secure-cookie/CSRF-origin bypass, and cache poisoning. P...

Prior to 0.4.112, the ckangetmqaquality and ckangetmqaqualitydetails tools in src/tools/quality.ts use isValidMqaServer to validate the serverurl parameter with a prefix-only regular expression for dati.gov.it, allowing suffix-host an...

CVE-2026-48061 Litestar: AllowedHostsMiddleware bypasses host validation via client-controlled X-Forwarded-Host header

Litestar is an Asynchronous Server Gateway Interface ASGI framework. In versions prior to 2.22.0, an attacker can bypass the allowed hosts validation by omitting the Host header and supplying an X-Forwarded-Host header set to a whitelisted domain. The AllowedHostsMiddleware trusts the...

CVE-2026-14596 DynamicKit for Elementor < 1.0.3 - Unauthenticated Account Takeover via Password Reset Link Host Injection

The DynamicKit for Elementor WordPress plugin before 1.0.3 does not validate the host of a user-supplied URL used as the base of the password-reset link it emails, allowing unauthenticated attackers to send a target user a legitimately-formatted reset email whose link points to an...

CVE-2026-14596

CVE-2026-14596 affects the DynamicKit for Elementor WordPress plugin prior to 1.0.3. The vulnerability arises because the plugin does not validate the host of a user-supplied URL used as the base for the password-reset link sent by email. This allows unauthenticated attackers to craft a legitimat...

CVE-2026-47209

vm2 (Node.js sandbox) had a vulnerability in the BaseHandler.set trap that ignores the receiver parameter and always writes to the host target, enabling inherited-property writes to leak onto host objects via prototype chains. This can allow attackers to assign Symbol-keyed properties (e.g., node...
