This will crash as Tink just assumes any valid JSON input will contain an object.\n\n\n  *  An adversary can crash binaries using the crypto::tink::JsonKeysetReader in tink-cc by providing an input containing many nested JSON objects. This may result in a stack overflow.\n\n\nWe recommend upgrading to version 2.1.3 or above","published":"2024-05-21T12:15:09.000Z","lastModified":"2026-06-17T08:01:51.000Z","status":"Analyzed","sourceIdentifier":"cve-coordination@google.com","cvss":{"version":"4.0","score":6.8,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-116"],"affected":["google/tink c\\+\\+"],"epss":{"score":0.00226,"percentile":0.13243,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.23%).
