Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The WeKnora package (Go module github.com/Tencent/WeKnora) before 0.3.0 has a DNS rebinding flaw in its web_fetch tool, where URL validation is performed on one DNS resolution and the headless browser resolves the hostname again during the fetch. An unauthenticated attacker who controls a domain can use this to reach internal services such as localhost or private network addresses, and potentially read sensitive data. Upgrade to version 0.3.0 or later.
