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
CVE-2026-34214 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 377,636 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.

Description
Summary
Iceberg connector REST catalog static credentials (access key) or vended credentials (temporary access key) are accessible to users that have write privilege on SQL level.
Details
Iceberg REST catalog typically needs access to object storage. This access can be configured in multiple different ways. When storage access is achieved by static credentials (e.g. AWS S3 access key) or vended credentials (temporary access key).
Query JSON is a query visualization and performance troubleshooting facility. It includes serialized query plan and handles for table writes or execution of table procedures. A user that submitted a query has access to query JSON for their query. Query JSON is available from Trino UI or via /ui/api/query/«query_id» and /v1/query/«query_id» endpoints.
The storage credentials are stored in those handles when performing write operations, or table maintenance operations. They are serialized in query JSON. A user with write access to data in Iceberg connector configured to use REST Catalog with static or vended credentials can retrieve those credentials.
Impact
Anyone using Iceberg REST catalog with static or vended credentials is impacted. The credentials should be considered compromised. Vended credentials are temporary in nature so they do not need to be rotated. However, underlying data could have been exposed.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.trino:trino-iceberg, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update io.trino:trino-iceberg to 480 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-34214 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 CVE-2026-34214 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-34214. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
