Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nuclei (github.com/projectdiscovery/nuclei/v3) versions 3.0.0 up to 3.10.0 are affected. A malicious target server can return response data that, when reused in a later DAST/fuzz step with the -env-vars (-ev) option enabled, causes scanner-host environment variables such as API keys or tokens to be disclosed. Upgrade to version 3.10.0 or later, or disable -ev when scanning untrusted targets.
