What happened

Summary

Aggregate functions (min, max) applied to fields with the conceal special type incorrectly return raw database values instead of the masked placeholder. When combined with groupBy, any authenticated user with read access to the affected collection can extract concealed field values, including static API tokens and two-factor authentication secrets from directus_users.

Details

Fields marked with conceal are protected by payload processing logic that replaces real values with a masked placeholder on read. This protection works correctly for standard item queries, but aggregate query results are structured differently, operations are nested under their function name rather than appearing as flat field keys.

Continue reading

The masking logic does not account for this nested structure, causing it to silently skip concealed fields in aggregate responses and return their raw values to the client.

Impact

- Account Takeover An authenticated attacker can harvest static API tokens for all users, including administrators, enabling immediate authentication as any account without credentials.

- 2FA Bypass TOTP seeds stored in directus_users can similarly be extracted, allowing an attacker to bypass two-factor authentication for any account.

Affected package ranges reported by GitHub: directus: < 11.17.0

About this data

This record was ingested from a data source. Retrieved: Nov 9, 2026, 02:35 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
