CVE-2024-0232Public exploit

Application crash via freed JSON cache read

Published Jan 16, 2024 · Updated Nov 21, 2025

Heap use-after-free in SQLite before 3.43.2 allows local users to crash an application by inducing it to process crafted JSON. A combination of json_set() and json_replace() overflows the JSON cache, after which jsonParseAddNodeArray() reads a freed heap allocation. A victim must run attacker-supplied SQL or data through an affected application; the demonstrated consequence is an application crash.
