MEDIUMView permissions are bypassed for paginated lists of ORM data
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
silverstripe/graphql🐘silverstripe/graphqlReal-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
Impact
canView permission checks are bypassed for ORM data in paginated GraphQL query results where the total number of records is greater than the number of records per page.
Note that this also affects GraphQL queries which have a limit applied, even if the query isn’t paginated per se.
This has been fixed by ensuring no new records are pulled in from the database after performing canView permission checks for each page of results. This may result in some pages in your query results having less than the maximum number of records per page even when there are more pages of results.
This behaviour is consistent with how pagination works in other areas of Silverstripe CMS, such as in GridField, and is a result of having to perform permission checks in PHP rather than in the database directly.
You can choose to disable these permission checks by disabling the CanViewPermission plugin following the instructions in overriding default plugins.
Note that this vulnerability does not affect version 3.x.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/graphql. 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 silverstripe/graphql to 4.3.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jgph-w8rh-xf5p 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-jgph-w8rh-xf5p 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-jgph-w8rh-xf5p. 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-jgph-w8rh-xf5p in your dependencies?
O3 detects GHSA-jgph-w8rh-xf5p across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
