Short explanation
CVE-2026-120194 affects the json-glib library, where the JSONPath slice evaluator used by json_path_query() can enter an infinite loop when given a slice expression with a negative step. This can lead to a denial of service.
Attackers can force applications into a hang and trigger a denial of service by evaluating attacker-controlled JSONPath expressions.
What should be done?
- Monitor vendor advisories and updates
- Apply updates when security patches become available
