Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Wagtail versions before 7.0.9, 7.1 through before 7.3.4, 7.4 through before 7.4.3, and 8.0rc1 before 8.0rc2 are affected. An attacker can send specially crafted HTTP headers to the document serve endpoint to learn whether a document with a given ID matches a known SHA1 hash, regardless of permissions, but cannot see document contents or other metadata. Upgrade to Wagtail 7.0.9, 7.3.4, 7.4.3, 8.0rc2, or later. Sites that cannot upgrade can strip If-Match and If-None-Match headers from anonymous requests to /documents/ at the reverse proxy.
