AI-suggested

If you cannot patch yet, avoid using the -env-vars option in multi-step templates against untrusted targets. Restrict usage to trusted inputs only to mitigate the risk of DSL expression injection.

Description

ProjectDiscovery Nuclei 3 before 3.8.0 allows DSL expression injection. This affects use of -env-vars for multi-step templates against untrusted targets (not the default configuration).
