CVE-2024-39924
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 · uneditedAn issue was discovered in Vaultwarden (formerly Bitwarden_RS) 1.30.3. A vulnerability has been identified in the authentication and authorization process of the endpoint responsible for altering the metadata of an emergency access. It permits an attacker with granted emergency access to escalate their privileges by changing the access level and modifying the wait time. Consequently, the attacker can gain full control over the vault (when only intended to have read access) while bypassing the necessary wait period.
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 · high confidenceVaultwarden 1.30.3 contains an authorization bypass in the emergency access metadata endpoint. An attacker with granted emergency access can modify their access level and wait time parameters, escalating from intended read-only access to full vault control while bypassing the configured wait period designed to allow the vault owner to reject the request.

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.
-
Check Vaultwarden versionRun `vaultwarden --version` or inspect the Docker container/image tag, or check the admin page for the version numberAffected if Version is exactly 1.30.3
-
Identify emergency access grantsQuery the database for emergency access records: look for entries in the emergency_access table, or use the Vaultwarden API endpoint GET /api/emergency-access to list all emergency access grantsAffected if Any emergency access grants exist (grantor_id and grantee_id entries are present)
-
Verify emergency access configurationCheck the Vaultwarden configuration file (e.g., environment variables or config.toml) for emergency_access_timeout and emergency_access_grant_wait_period settings, and verify whether emergency access feature is enabledAffected if Emergency access is enabled and grants have been created
-
Audit emergency access permissionsQuery the emergency_access table or use GET /api/emergency-access/{id} to inspect the current wait_time_days and permission level (read-only vs full) for each grant, checking for any grants with permission set to 'full' or wait_time less than expected configured delayAffected if Any grant shows full control permission or wait_time has been shortened from the configured value
A user is affected if running Vaultwarden version 1.30.3 and any emergency access grants exist in the environment
