CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote authenticated user to execute arbitrary code.

When using the local_batch client from salt-api in SaltStack Salt before 2015.8.13, 2016.3.x before 2016.3.5, and 2016.11.x before 2016.11.2, external authentication is not respected, enabling all authentication to be bypassed.
