CVE-2026-44197
MEDIUMCVE-2026-44197 is a medium-severity (CVSS 6.5) CWE-280 vulnerability in wagtail. O3 Security confirms whether CVE-2026-44197 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Wagtail: Improper permission handling when comparing revisions
Blast Radius
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
Wagtail is an open source content management system built on Django. Prior to 7.0.7, 7.3.2, and 7.4, a CMS user without the ability to edit a page could access revisions of the page through the revision compare view if they knew the primary key of two revisions. This could potentially result in disclosure of sensitive information. This vulnerability is fixed in 7.0.7, 7.3.2, and 7.4.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | wagtail | all versions | 7.0.7 |
| 🐍PyPI | wagtail | ≥ 7.1&&< 7.3.2 | 7.3.2 |
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 CVE-2026-44197 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 CVE-2026-44197 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 CVE-2026-44197. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
