Anonymous cache poisoning via XHR requests in Discourse
Summary
Anonymous cache poisoning via XHR requests in Discourse
Original description
The description as published by the source.
Discourse is an open source platform for community discussion. An attacker can make several XHR requests until the cache is poisoned with a response without any preloaded data. This issue only affects anonymous visitors of the site. This problem has been patched in the latest version of Discourse. Users are advised to upgrade. Users unable to upgrade should disable anonymous cache by setting the DISCOURSE_DISABLE_ANON_CACHE environment variable to a non-empty value.
