Summary
Wagtail, a Python content management system, has a flaw in its document serving endpoint that lets an attacker check whether a document with a given ID matches a specific SHA1 hash, regardless of permission restrictions. The attacker can only confirm a hash they already know and cannot view the document's contents or other metadata.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.
Read the original description
Impact
By passing specific HTTP headers to the document serve URL endpoint, an attacker was able to determine whether a document with a given ID matched a specified SHA1 hash, regardless of any permission restrictions on the document or knowing its filename. This could allow an attacker to determine whether a document with a specific known hash is present in the Wagtail document library.
This vulnerability does not expose the document's contents or any metadata beyond the already known SHA1 hash, and does not expose information about any documents for which the attacker does not know the SHA1 hash.
Patches
Patched versions have been released as Wagtail 7.0.9, 7.3.4, 7.4.3 and 8.0rc2.
Workarounds
Site owners who are unable to upgrade can strip If-Match and If-None-Match from anonymous requests to /documents/ at the reverse proxy, or use a custom document model without a file_hash attribute.

Questions about GHSA-92HV-J533-69WC
Is GHSA-92HV-J533-69WC being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
