Which packages are affected by GHSA-x27p-5f68-m644?

GHSA-x27p-5f68-m644 affects the following packages: io.trino:trino-iceberg (Maven). Ecosystems affected: Maven.

How do I fix GHSA-x27p-5f68-m644?

Update io.trino:trino-iceberg to 480 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x27p-5f68-m644 is resolved across your whole dependency graph.

How do I detect GHSA-x27p-5f68-m644 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.trino:trino-iceberg. 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.

How do I mitigate GHSA-x27p-5f68-m644 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-x27p-5f68-m644?

O3 pinpoints whether GHSA-x27p-5f68-m644 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-x27p-5f68-m644 actively exploited in the wild?

No public exploit code has been indexed for GHSA-x27p-5f68-m644 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-x27p-5f68-m644?

GHSA-x27p-5f68-m644 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 9th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-x27p-5f68-m644?

GHSA-x27p-5f68-m644 is classified as CWE-212 (CWE-212), CWE-312 (CWE-312). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-x27p-5f68-m644 published, and has it been updated?

GHSA-x27p-5f68-m644 was published on March 29, 2026 and was last updated on March 31, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

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.
