Weakness: CWE-200

Description

Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, Directus stores revision records (in directus_revisions) whenever items are created or updated. Due to the revision snapshot code not consistently calling the prepareDelta sanitization pipeline, sensitive fields (including user tokens, two-factor authentication secrets, external auth identifiers, auth data, stored credentials, and AI provider API keys) could be stored in plaintext within revision records. This vulnerability is fixed in 11.17.0.

Affected products
