Machine-written summary

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

Anki's local HTTP server in the aqt package, versions before 25.9.3, does not block requests from other origins despite its CORS setup. A malicious website could use a browser to make side-effecting requests to the server, with the impact varying by browser. The source gives few details on exploitation conditions. Upgrade aqt to version 25.9.3 or later.
