OmniAuth is a flexible authentication system utilizing Rack middleware. Prior to 2.2.0, OmniAuth derives provider callback URLs from request-controlled host information when neither a fixed full_host nor framework-level incoming host validation is configured. A remote unauthenticated client can supply a forged Host header, creating a host header injection risk in applications whose web framework does not verify incoming host headers. Applications using appropriately configured Rails host authorization or a fixed full_host are not affected by this path. This issue is fixed in version 2.2.0.

———GPUStack is an open-source GPU cluster manager for AI model serving and GPU instance provisioning. Prior to 2.2.0, get_current_user in gpustack/api/auth.py treated a loopback request source as the built-in administrator when force_auth_localhost was false, which was the default. A remote request could appear to originate from 127.0.0.1 because client_ip_getter accepted a same-host reverse proxy peer or a client-supplied X-GPUStack-Real-IP loopback value. The bypass allowed unauthenticated administrative access, including user and model changes, persistent administrator API-key creation, disclosure of worker and cloud-provider secrets, and code execution through POST /v2/inference-backends/from-yaml. Exploitation was observed in the wild against a 2.1.1 deployment. This issue is fixed in version 2.2.0.6hCVE-2026-927048.3 HIG—
———SharpEmu is an experimental PlayStation 5 emulator for Windows and Linux. In version 0.0.3-release.3 and earlier, the repository-provided debugger frontend tooling is vulnerable while running. This tooling is not included in the release archives. The frontend exposes an HTTP API on 127.0.0.1:8765 without authentication or CSRF token. Its do_POST handler in tools/SharpEmu.DebuggerFrontend/debugger_frontend.py does not validate the Origin, Referer, Sec-Fetch-Site, or Host headers. The _read_json_body() function also accepts JSON sent with browser-simple content types instead of requiring application/json . A malicious page that can reach the loopback listener can send cross-origin requests to /api/launch , /api/command , and /api/connect . Chromium may require Local Network Access permission for pages served from public origins. Local-origin pages and other delivery paths are not consistently subject to this restriction. The /api/launch endpoint accepts an attacker-selected emulatorPath if it points to an existing file on the victim’s host. On POSIX systems, that file must also be executable. The endpoint additionally requires an existing ebootPath . The /api/command endpoint exposes debugger operations, including write-memory , set-register , and continue . The /api/connect endpoint can initiate outbound TCP connections. These operations can let an attacker execute an existing binary with the victim’s privileges, control the attached emulated process, or reach network services accessible from the host. DNS rebinding can additionally let the attacker read API responses interactively. This issue is fixed in version 0.0.3-release.3-patch.112hCVE-2026-121145——
———This vulnerability exists in the iRA 2.0 and iRA.ev mobile applications due to insufficient validation of URLs and origins loaded within the WebView component. A remote attacker could exploit this vulnerability by sending malicious web content to the affected WebView.
Successful exploitation of this vulnerability could allow the attacker to perform unauthorized interaction with application functionality, obtain live bearer authentication tokens and potentially impersonate the associated user and access vehicle related information and services.15hCVE-2026-1144566.5 MED—
———Multiple Snowflake client drivers implementing the `authenticator=externalbrowser` single sign-on flow could have allowed an attacker to interfere with a user's login attempt through weaknesses in the local loopback callback listener used to receive the identity provider's response. The listener reflected an arbitrary request's Origin header into its CORS response headers and accepted the first token-bearing request it received during the login window without verifying a CSRF state value bound to that specific login attempt. An attacker able to reach the listener during an active login might have leveraged this to submit a forged callback response, causing the authentication attempt to fail. The fix is available in Snowflake Connector for Python 4.8.0, Snowflake Go Driver v2.3.0, Snowflake JDBC Driver 4.4.0 (including the snowflake-jdbc-fips and snowflake-jdbc-thin artifacts), Snowflake Node.js Driver 3.4.0, Snowflake Connector for .NET 6.3.0, Snowflake ODBC Driver 4.0.0, Snowflake PHP PDO Driver 4.3.0, and libsnowflakeclient 2.11.1. Go v1 users must migrate to the latest major version of the module. Users must manually upgrade.8hCVE-2026-1218029.1 CRI—
——0@better-auth/expo before 1.7.16 allows certain account-takeover outcomes (e.g., unauthenticated changes of any account's email address), because it signs a caller-supplied state value without checking whether that value had been issued by the server.
