Technical description

Nuxt is an open-source web development framework for Vue.js. From @nuxt/webpack-builder 3.0.0 and @nuxt/rspack-builder 3.12.2 until 4.6.4, the development middleware trusts Origin, Referer, or Sec-Fetch-Site when the Host header names the same attacker-controlled hostname. After DNS rebinding changes that hostname to a loopback address, a malicious page opened by a developer can read /_nuxt/*.js client chunks and inline source maps, exposing compiled application source, local filesystem paths, and developer-controlled values embedded in the client bundle. The attacker must know or guess the development-server port and induce the developer to open the malicious page; Chrome 142 and later and other Chromium-based browsers that enforce Local Network Access restrictions prompt before a public page can reach the loopback address. The default Vite builder and production builds are unaffected. This issue is fixed in version 4.6.4.

CVE-2026-124762—

———P-Net before 1.0.4 finds the RPC session of a received PDU by its activity UUID only, and a reject, fault or cancel PDU for the session aborts the Application Relationship, without checking that the PDU is the answer to a call of the device or where it comes from. A host with ADJACENT network access that has observed the activity UUID of the connection, which is sent in clear in every RPC request, can abort the Application Relationship with one PDU. It also allocates a session for an unknown activity UUID and changes the address stored for an existing session.5h CVE-2026-124759—

———P-Net before 1.0.4 routes a received RTA alarm frame to an Application Relationship using only the destination alarm reference in the frame, without checking the source of the frame. A host with ADJACENT network access can abort an established Application Relationship with a single alarm ERROR frame, or deliver forged alarm notifications with chosen type, slot, subslot, USI and payload to the application.11h CVE-2026-1280447.7 HIG

——0OpenMage magento-lts before 20.18.2 and 21.x before 21.0.0-beta3 validates OAuth 1.0a oauth_callback URLs with a string-prefix check and falls back to accepting any well-formed URL. Attackers holding a leaked consumer key and secret can supply host-suffix, userinfo, or arbitrary callback URLs to capture an approving administrator's or customer's request token and verifier, then obtain an access token with the victim's API privileges.10h CVE-2026-1262685.3 MED

——0NocoDB before 2026.08.0 contains an IP address spoofing vulnerability that allows unauthenticated attackers to forge their recorded source IP by supplying X-Forwarded-For headers, because Express trust proxy is enabled unconditionally. Attackers can write arbitrary source addresses into audit and request logs to mislead investigations and evade the per-address public API rate limiter.15h CVE-2026-65957—

——4Helio is an MCP proxy that sits between AI agents and the tools they use. Prior to version 0.8.0, the dashboard sideband (default 127.0.0.1:3100) validated CORS request origins by matching the hostname against a private-network string prefix (10., 172.16.–172.31., 192.168.) rather than validating an IP address. A public DNS name such as 192.168.attacker.com, 10.evil.io, or 172.16.pwn.example also satisfies that prefix, so the proxy echoed the attacker origin in Access-Control-Allow-Origin. This issue has been patched in version 0.8.0.1d CVE-2026-89326—
