The problem has been fixed in: Netdata agent v1.37 (stable) and Netdata agent v1.36.0-409 (nightly). As a workaround, do not enable streaming by default. If you have previously enabled this, it can be disabled. Limiting access to the port on the recipient Agent to trusted child connections may mitigate the impact of this vulnerability.","status":"published","published":"2023-01-14T02:15:00Z","modified":"2026-02-04T02:15:31.202533Z","cvss":[{"version":"3.1","score":6.5,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","level":"medium"},{"version":"3.1","score":9.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","level":"critical"}],"updated_at":"2026-11-02T16:54:20.198616Z"},{"id":"USN-7250-1","title":"netdata vulnerabilities","description":"It was discovered that Netdata incorrectly handled parsing JSON input,\nwhich could lead to a JSON injection.
