Information disclosure via excluded-column predicate oracle
Published Jul 21, 2026 · Updated Jul 21, 2026
Information disclosure in Electric Postgres Sync before 1.6.10 allows remote authenticated users to infer excluded column values. The subset__where handler evaluates predicates against columns omitted by columns and reveals each match through the rows returned in a shape response. Exploitation requires a deployment that treats columns as a field-level access control and grants the requester access to issue subset filters; it discloses inferred values without returning the excluded fields.

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.
