Affected by this vulnerability is the function child_process.exec of the file src/gitUtils.ts of the component show_merge_diff/quick_merge_summary/show_file_diff. The manipulation results in os command injection. The attack must be initiated from a local position. The exploit has been made public and could be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. It is advisable to implement a patch to correct this issue. The vendor was contacted early about this disclosure but did not respond in any way."
