CVE-2026-105856

Impact

An attacker who has read plus create or update access to a collection can submit a request that includes a SQL injection targeting a specific field path shape and operators in Payload's SQLite and Postgres.

You are affected if:

• You use @payloadcms/db-sqlite or @payloadcms/db-d1-sqlite.
• You use @payloadcms/db-postgres or @payloadcms/db-vercel-postgres < 3.73.0.
• A readable collection has a json field, or a blocks field with blocksAsJSON: true.
• The attacker has read plus create or update access on it.

You are not affected if:

• You have no json or blocksAsJSONfields.richText` is not affected.
• You run a patched version.

Patches

The patched version sanitizes the query input to prevent injection.

Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
