Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Crawlee for Python versions 1.0.0 up to but not including 1.7.0 are vulnerable to server-side request forgery through sitemap and robots.txt content, where URLs pointing to internal hosts or non-HTTP schemes could be queued and fetched by the crawler. An attacker who controls a sitemap or robots.txt the crawler fetches can make it issue requests inside its network, which is mainly blind probing, and with CurlImpersonateHttpClient non-HTTP schemes such as gopher or file become reachable. Upgrade to crawlee 1.7.0, which is listed as the fixed version.
