CVE-2026-18061: Amazon Advanced Jdbc Wrapper

Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days.

Improper restriction of XML external entity references in the RemoteQueryCachePlugin in AWS Advanced JDBC Wrapper 3.3.0 through 4.2.0 might allow an actor with write access to the shared cache infrastructure to disclose sensitive files from application hosts that read cached query results, including stored database and IAM role credentials, via crafted XML data in a cached column value. To remediate this issue, users should upgrade to version 4.3.0 or later.

Affected products

• Amazon Advanced Jdbc Wrapper: from 3.3.0, before 4.3.0 (fixed in 4.3.0)
