Authorization bypass via reserved job argument injection
Published Aug 30, 2026 · Updated Aug 30, 2026
Improper input handling in AshOban 0.2.5 through 0.8.13 allows attackers to retarget update or destroy jobs across records and tenants. AshOban.build_trigger/3 merges trusted atom-keyed job arguments with caller-controlled string-keyed :args, and JSON persistence resolves the duplicate names to the caller's values. Exploitation requires an application to pass untrusted input into :args for an update or destroy trigger, enabling unauthorized modification or deletion of another record.
