CVE-2025-32023 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the hyperloglog process. An attacker can execute arbitrary code or alter application data by submitting a specially crafted string to trigger an out-of-bounds write during hyperloglog operations.
Workaround
This vulnerability can be mitigated by restricting access to hyperloglog operations using ACL to prevent users from executing HLL commands.
