Real-World Exposure
collective-taskReal-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
A vulnerability was found in collective.task up to 3.0.8. It has been classified as problematic. This affects the function renderCell/AssignedGroupColumn of the file src/collective/task/browser/table.py. The manipulation leads to cross site scripting. It is possible to initiate the attack remotely. Upgrading to version 3.0.9 is able to address this issue. The name of the patch is 1aac7f83fa2c2b41d59ba02748912953461f3fac.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for collective-task. 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 collective-task to 3.0.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-4527 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-2022-4527 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-2022-4527. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
