Which packages are affected by GHSA-92hv-j533-69wc?

GHSA-92hv-j533-69wc affects the following packages: wagtail (PyPI), wagtail (PyPI), wagtail (PyPI), wagtail (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-92hv-j533-69wc?

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.

How do I detect GHSA-92hv-j533-69wc in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wagtail, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-92hv-j533-69wc if there is no patch (or I can't update yet)?

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.

Is GHSA-92hv-j533-69wc actively exploited in the wild?

No public exploit code has been indexed for GHSA-92hv-j533-69wc yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-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.
