CVE-2026-40074 MEDIUM PATCH GHSA This Month

SvelteKit versions prior to 2.57.1 are vulnerable to denial of service when the redirect() function is called from the handle server hook with HTTP header-invalid characters in the location parameter. An unauthenticated remote attacker can trigger an unhandled TypeError by supplying unsanitized user input to the redirect location, potentially causing application crashes on certain platforms. The vulnerability is fixed in version 2.57.1.

CVE-2026-27195 HIGH PATCH This Week

Wasmtime versions 39.0.0 and later experience a denial-of-service panic when async WebAssembly component functions are called and then abandoned by the host before completion, such as when the Future is dropped after a single poll during an async yield. This affects applications using Wasmtime's component model with async support, allowing an attacker to crash the runtime through specially crafted async function invocations. A patch is available to address this stability issue.

Cube.js versions 1.1.17 through 1.5.12 and 1.4.x before 1.4.2 are vulnerable to denial of service attacks where an authenticated attacker can craft a malicious request to completely disable the Cube API. This network-accessible vulnerability requires valid credentials but no user interaction, making it exploitable by any authenticated user with API access. No patch is currently available for affected versions.

Juniper Junos OS SRX Series suffers a denial of service vulnerability in the packet forwarding engine when PowerMode IPsec and GRE performance acceleration are both enabled, allowing remote attackers to crash the device by sending a specially crafted ICMP packet through a GRE tunnel. The crash results in immediate traffic loss and device restart, affecting systems with both features active on vulnerable SRX platforms. No patch is currently available.

CVE-2026-0203 MEDIUM This Month

Juniper Junos OS Forwarding Plane Crash (FPC) denial of service occurs when a network-adjacent attacker sends a specially crafted ICMPv4 packet with a malformed IP header, causing the affected line card to crash and restart. The attack is limited to directly adjacent networks since upstream routers filter such malformed packets before forwarding. No patch is currently available for this vulnerability affecting multiple Junos OS versions.

CVE-2025-66622 HIGH PATCH This Week

A serialization bug in matrix-sdk-base allows remote attackers to cause denial-of-service by sending rooms with custom m.room.join_rules values, which stalls the sync process and prevents all room processing. The vulnerability affects matrix-sdk-base versions 0.14.1 and prior and has a high availability impact (CVSS 7.5) with a patch available in version 0.16.0. With a low EPSS score of 0.06% and no KEV listing, this represents a moderate real-world risk primarily concerning service availability rather than active exploitation.
