DescriptionGitHub Advisory
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.
AnalysisAI
Trino's Iceberg connector leaks AWS S3 access credentials through query JSON endpoints, allowing authenticated users with write privileges to extract static or temporary credentials used for object storage access. The vulnerability exposes credentials via the query visualization API (/ui/api/query/ and /v1/query/ endpoints) when users perform write or table maintenance operations. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires Iceberg connector REST catalog configured with static AWS S3 credentials or temporary vended credentials for object storage access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability presents moderate-to-high real-world risk despite the 7.7 CVSS score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated Trino user with write privileges on Iceberg tables initiates a routine INSERT operation or table maintenance procedure such as OPTIMIZE or DELETE. After query completion, the attacker accesses their own query details via the Trino web UI or directly calls the /v1/query/[query_id] REST endpoint using their valid session credentials. … |
| Remediation | Vendor-released patch: version 480. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all Trino deployments using Iceberg connectors and identify which systems expose /ui/api/query/ or /v1/query/ endpoints. …
