Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Json-glib: json-glib: infinite loop in json_path_query() with negative jsonpath slice step

A flaw was found in json-glib. The JSONPath slice evaluator used by json_path_query() can enter an infinite loop when given a slice expression with a negative step. An application that evaluates attacker-controlled JSONPath expressions can be forced into a hang, leading to a denial of service.
