CVE intelligence and bounded remediation
CVE-2022-23460 — Jsonxx or Json++ is a JSON parser, writer and reader written in C++
Jsonxx or Json++ is a JSON parser, writer and reader written in C++. In affected versions of jsonxx json parsing may lead to stack exhaustion in an address sanitized (ASAN) build. This issue may lead to Denial of Service if the program using the jsonxx library crashes. This issue exists on the current commit of the jsonxx project and the project itself has been archived. Updates are not expected. Users are advised to find a replacement.

Matched remediation archetype
Buffer bounds, memory safety, and memory corruption
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
- Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
- Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.
Remediate safely
- Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
- Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
- Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
