Authenticated user data exposure via eager-loaded thread users
Published Sep 28, 2022 · Updated May 21, 2025
Exposure of sensitive information in ToolJet before 1.26.0 allows remote authenticated users to read other users' account data through an app thread endpoint. The thread service eagerly loaded complete User entities for thread records, returning fields beyond the permitted identity attributes; the fix joins users and selects only id, firstName, and lastName. An editor in the same application as the victim is required, so the impact is cross-user confidentiality loss within that app rather than unauthenticated access.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
