GHSA-92hv-j533-69wc
LOWGHSA-92hv-j533-69wc is a low-severity (CVSS 3.7) vulnerability in wagtail. O3 Security confirms whether GHSA-92hv-j533-69wc is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Wagtail: Identification of documents by SHA1 hash
Real-World Exposure
wagtail🐍wagtail🐍wagtail🐍wagtailReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wagtail. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update wagtail to 7.0.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-92hv-j533-69wc is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-92hv-j533-69wc is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-92hv-j533-69wc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-92hv-j533-69wc in your dependencies?
O3 detects GHSA-92hv-j533-69wc across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
