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
github.com/crossplane/crossplane🐹github.com/crossplane/crossplaneReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Impact
An high-privileged user could create a Package referencing an arbitrarily large image containing that Crossplane would then parse, possibly resulting in exhausting all the available memory and therefore in the container being OOMKilled.
The impact is low due to the high privileges required to be able to create the Package and the eventually consistency nature of controller.
Patches
The problem has been fixed in 1.11.5, 1.12.3 and 1.13.0, all the supported versions of Crossplane at the time of writing.
Workarounds
Only using images from trusted sources and keeping Package editing/creating privileges to administrators only, which should be both considered already best practices.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/crossplane/crossplane. 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 github.com/crossplane/crossplane to 1.11.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-68p4-95xf-7gx8 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-68p4-95xf-7gx8 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-68p4-95xf-7gx8. 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-68p4-95xf-7gx8 in your dependencies?
O3 detects GHSA-68p4-95xf-7gx8 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
