CVE-2026-33420 Details
Description
Vaultwarden is a Bitwarden-compatible server written in Rust. In version 1.35.4 and earlier, the get_org_collections_details endpoint (GET /api/organizations/{org_id}/collections/details) is missing the has_full_access() authorization check that exists on the sibling get_org_collections endpoint. This allows any Manager-role user with accessAll=False and no collection assignments to retrieve the names, UUIDs, user-to-collection mappings, and group-to-collection mappings for all collections in the organization. This issue has been fixed in version 1.35.5.
A vulnerability exists in Vaultwarden versions through 1.35.4, specifically in the get_org_collections_details endpoint. This endpoint lacks the necessary has_full_access authorization check, which is present in the related get_org_collections endpoint. As a result, any Manager-role user with accessAll=False and no collection assignments can access the names, UUIDs, and user-to-collection and group-to-collection mappings for all collections within the organization. This issue has been addressed in version 1.35.5.
Users are advised to update to Vaultwarden version 1.35.5, where this vulnerability has been fixed.
