GitHub report says Claude Code put the user's email address in the User-Agent header of four Wikipedia search requests
A GitHub issue filed on 15 October 2026 against Claude Code (version 2.1.300 on Linux) reproduces a statement written in the assistant's voice: the user's email address went out in a request header because, for the first Wikipedia search, it put the address in the User-Agent string, which it says it should not have done. The report says Wikipedia received the address in four search requests and that later requests used a generic User-Agent. Version 2.1.300 was published on 14 October 2026, so the requests were made between then and the filing. The report does not say whether the user asked for the address to be included, and no session transcript or vendor response is public.
