The RemoteQueryCachePlugin uses ObjectInputStream without class filtering when deserializing cached query results from Redis or Valkey, enabling gadget chain execution when cache entries are poisoned.\n\n\n\nWe recommend upgrading to AWS Advanced JDBC Wrapper version 4.0.1 or later.","published":"2026-07-01T20:17:08.000Z","lastModified":"2026-10-25T16:10:00.000Z","status":"Analyzed","sourceIdentifier":"ff89ba41-3aa1-4d27-914a-91399e9639e5","cvss":{"version":"4.0","score":7.7,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-502"],"affected":["amazon/advanced jdbc wrapper"],"epss":{"score":0.00727,"percentile":0.5389,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.73%).
