Machine-written summary

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

Nuclei (Go module github.com/projectdiscovery/nuclei/v3) versions 3.0.0 up to but not including 3.10.0 are affected. A workflow that references a file-protocol template can run it without the -file flag, which normally blocks local file reads, so an attacker who supplies an untrusted workflow could read local files on the scanner host. Upgrade to Nuclei 3.10.0 or later; until then, do not run workflows from untrusted sources.
