Real-World Exposure
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
A CMS user without the ability to edit a page could still access the history report for the page, potentially resulting in disclosure of sensitive information.
Patches
Patched versions have been released as Wagtail 7.0.7 and 7.3.2. The new 7.4 LTS feature release also incorporates this fix.
Workarounds
No workaround is available.
Acknowledgements
Wagtail thanks Seoyoung Kang @seoyoung-kang who is from AhnLab and also an independent security researcher for reporting this issue.

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 7.0.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c4mr-889m-vgf6 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-c4mr-889m-vgf6 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-c4mr-889m-vgf6. 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-c4mr-889m-vgf6 in your dependencies?
O3 detects GHSA-c4mr-889m-vgf6 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
