CVE-2026-5420 Details
Description
A security flaw has been discovered in Shinrays Games Goods Triple App up to 1.200. The affected element is an unknown function of the file jRwTX.java of the component cats.goods.sort.sorting.games. Performing a manipulation of the argument AES_IV/AES_PASSWORD results in use of hard-coded cryptographic key . Attacking locally is a requirement. The complexity of an attack is rather high. The exploitability is described as difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A vulnerability exists in Shinrays Games Goods Triple App, specifically in the Cats Goods Sort component, version 1.200. The issue arises from an unknown function in the file jRwTX.java, where a hard-coded AES key and initialization vector (IV) are embedded. This vulnerability allows attackers to extract these static values through reverse engineering, potentially enabling them to decrypt sensitive server responses, such as AppsFlyer attribution data. The vulnerability requires local exploitation and is considered complex, although a public exploit is available.
