Real-World Exposure
silverstripe/framework🐘silverstripe/frameworkReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
There is a user ID enumeration vulnerability in our brute force error messages.
- Users that don't exist in will never get a locked out message
- Users that do exist, will get a locked out message
This means an attacker can infer or confirm user details that exist in the member table.
This issue has been resolved by ensuring that login attempt logging and lockout process works equivalently for non-existent users as it does for existant users.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update silverstripe/framework to 3.4.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g84q-cq55-xwgp 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-g84q-cq55-xwgp can be triaged on real exposure rather than presence alone.
Tailored to GHSA-g84q-cq55-xwgp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
