Machine-written summary

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

Versions of github.com/tinfoil-factory/netfoil before 0.3.0 write domain names to the log without first checking that they contain only allowed characters. The source gives few details on who can supply those names or what an attacker gains, and says the impact depends on how the logs are used. Upgrade to version 0.3.0 or later; no workaround is listed.
