FKIE_CVE-2026-90714

Vulnerability from fkie_nvd - Published: 2026-09-14 13:19 - Updated: 2026-09-14 20:56
Severity
6.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Summary
A weakness has been identified in marcobambini Gravity up to 0.9.7. The impacted element is an unknown function of the file src/utils/gravity_json.c of the component JSON parser. This manipulation causes memory corruption. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 0.9.8 is sufficient to resolve this issue. Patch name: 9b337c3eae5833c3956bed1fc01c21c14fd443f2. It is suggested to upgrade the affected component.
