CVE-2025-49653
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedExposure of sensitive data in active sessions in Lablup's BackendAI allows attackers to retrieve credentials for users on the management platform.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a session-based sensitive data exposure vulnerability in Lablup's BackendAI platform. Attackers can retrieve user credentials from active sessions, likely due to improper handling or storage of authentication tokens/secrets within session data that should have been protected or not persisted.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify BackendAI versionLocate the installed BackendAI package and determine its version number using the package manager or version file (e.g., pip show backendai, docker image tag, or check version file in the installation directory).Affected if The installed version falls within any vulnerable version range provided for CVE-2025-49653 (if known).
-
Examine session storage configurationInspect the BackendAI configuration files and session management settings to determine how sessions are stored (server-side file, database, memory, etc.) and whether encryption is enabled for session data.Affected if Session storage is not encrypted, uses client-side sessions, or lacks proper encryption for sensitive session data.
-
Inspect active session data for credentialsAccess the session storage (database, file system, or memory depending on configuration) and examine stored session objects to check whether authentication tokens, passwords, API keys, or other credentials are present in the session data.Affected if User credentials, authentication tokens, or secrets are found stored within session objects.
-
Check session isolation settingsReview the session configuration to verify that session data is properly isolated per user and that one user cannot access another user's session data.Affected if Sessions are not properly isolated between users, or session data is accessible across user contexts.
-
Verify credential handling in authentication flowReview or trace the authentication code paths to confirm that credentials are not being written to session objects during login or token generation.Affected if The authentication flow stores credentials or authentication secrets directly into session storage.
A user is affected if their BackendAI installation stores authentication credentials or secrets within session data, lacks session encryption, or allows improper access to other users' session information.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper session data isolation and ensure credentials are never stored in session objects; use server-side session storage with appropriate encryption and avoid exposing authentication secrets in any client-accessible session data.
