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.
How urgent is this, really
GHSA-vr2x-7687-h6qv plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 376,715 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

Description
Impact
Resource properties secured with the security option of the ApiPlatform\Metadata\ApiProperty attribute can be disclosed to unauthorized users. The problem affects most serialization formats, including raw JSON, which is enabled by default when installing API Platform. Custom serialization formats may also be impacted. Only collection endpoints are affected by the issue, item endpoints are not. The JSON-LD format is not affected by the issue.
The result of the security rule is only executed for the first item of the collection. The result of the rule is then cached and reused for the next items. This bug can leak data to unauthorized users when the rule depends on the value of a property of the item. This bug can also hide properties that should be displayed to authorized users.
Patches
This issue impacts the 2.7, 3.0 and 3.1 branches. Upgrade to v2.7.10, v3.0.12 or v3.1.3.
Workarounds
Replace the cache_key of the context array of the Serializer inside a custom normalizer that works on objects if the security option of the ApiPlatform\Metadata\ApiProperty attribute is used.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for api-platform/core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update api-platform/core to 3.0.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vr2x-7687-h6qv 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-vr2x-7687-h6qv can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vr2x-7687-h6qv. 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-vr2x-7687-h6qv in your dependencies?
O3 Security finds GHSA-vr2x-7687-h6qv across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
