The invention discloses a device and a method for detecting application program vulnerabilities. The device comprises an interprocess control flow graph construction module, a forward solver, an optimization module, a backward solver and a flow sensitive path generator. According to the device, an activation point is ignored in the propagation process of the forward solver and the backward solver, so that the flow sensitivity is sacrificed, a large number of data flow values are prevented from being copied, the number of the data flow values is reduced, the flow sensitivity is recovered through a flow sensitive path generator, a flow sensitive stain propagation path is generated by using a deep search algorithm, and the flow sensitivity is improved. The performance and the expandability of the multi-solver IFDS algorithm are ensured, and then the vulnerability of the application program to be detected can be accurately detected.
