Name of the Vulnerable Software and Affected Versions SaltStack Salt versions prior to 3002.5

Description An issue was discovered in SaltStack Salt where the jinja renderer does not protect against server-side template injection attacks. This could allow a remote attacker to execute arbitrary code due to errors in input validation.

Recommendations For versions prior to 3002.5, update to version 3002.5 or later to resolve the issue. As a temporary workaround, consider disabling the jinja renderer until a patch is available. Restrict access to the wheel.pillar roots.write component to minimize the risk of exploitation. Avoid using the jinja renderer for rendering untrusted templates until the issue is resolved.
