CVE-2026-5420Public exploit

Protected-data disclosure via hard-coded AES credentials

Published Apr 2, 2026 · Updated Apr 2, 2026

Hard-coded cryptographic keys in Shinrays Games Goods Triple: Cat Good Sorting 1.200 and earlier allow local users to read protected data. The jRwTX.java code in cats.goods.sort.sorting.games uses fixed AES_IV and AES_PASSWORD values as AES key material instead of obtaining changeable secrets. Exploitation requires local low-privileged access and high-complexity manipulation of those values; the reported impact is recovery of encrypted application data, with no integrity or availability effect.
