Descripción técnica

Onyx 4.6.6 fails to properly restrict access to custom tool credentials stored in custom_headers, allowing any authenticated user to read admin-defined API keys. Attackers with basic authentication can call GET /tool/{tool_id} or GET /tool endpoints to retrieve plaintext authorization headers and third-party API credentials, then use them to directly access upstream APIs.

——0NetBox through 4.7.0 fails to redact sensitive data source backend credentials in REST and GraphQL API responses. Authenticated users with only view permission can retrieve plaintext passwords and secret keys for Git and Amazon S3 backends through API endpoints, gaining unauthorized access to external repositories and storage buckets.3h CVE-2026-53603—

——0nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. Prior to version 0.3.8, Operator session tokens are stored in plaintext in the operator_sessions table (the token column is the PRIMARY KEY). The session token is a 32-byte random hex value sent directly in a cookie and valid for 24 hours. Anyone who can read the database (backup, snapshot, file copy, or SQL-level disclosure) obtains every active session token and can hijack operator sessions directly, with no further authentication. This issue has been patched in version 0.3.8.18h CVE-2026-88627.5 ALT

——4IBM Netezza Software 11.3.0.3 through Interim Fix 002 has credentials that are hardcoded in the application source code, allowing unauthorized access to the container registry. The exposed secret enables attackers to pull private container images, potentially revealing proprietary code, configuration details, and other sensitive information.19h CVE-2026-751366.1 MED

——0UpSignOn for Windows before 7.19.0 contains an insecure credential storage vulnerability that allows local attackers to retrieve the biometric unlock key stored in the Windows PasswordVault API without triggering any authentication prompt. Attackers can access the stored biometric key from a standard local process within the same Windows session to decrypt the protected vault files and export the entire password manager contents in cleartext.2d CVE-2026-558605.9 MED

——1MariaDB Connector/R2DBC is a non-blocking MariaDB and MySQL client implemented in Java. Prior to 1.4.1, org.mariadb:r2dbc-mariadb does not gate clear-text password authentication plugins on transport encryption because the AuthenticationPlugin interface has no capability for a plugin to require a secure connection. A hostile or man-in-the-middle MariaDB server can send an AuthSwitchRequest naming mysql_clear_password or dialog (PAM) over a plain-TCP unencrypted connection, and AuthenticationFlow permits ClearPasswordPluginFlow or PamPluginFlow to return the user's password as cleartext bytes on the wire. The disclosed credentials can subsequently be used to authenticate directly to the database server. This issue is fixed in version 1.4.1.5d CVE-2026-822887.5 ALT

——7Stable Diffusion WebUI through 1.10.1 contains a credential disclosure vulnerability in the /sdapi/v1/cmd-flags endpoint that returns parsed command-line arguments including gradio_auth and api_auth values in cleartext. Unauthenticated attackers can access this endpoint to retrieve configured usernames and passwords, then use them to authenticate to the interface and access the application.8d
