Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the _strindices function due to missing runtime type checks on input arguments. An attacker can cause a crash and potentially disclose limited memory contents by supplying crafted input that leads to a controlled pointer dereference and memory read. This is only exploitable if untrusted jq filters are evaluated against a release build compiled with -DNDEBUG.
