CVE-2026-119922
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk46th percentile - higher than 46% of all known CVEs
Summary
Improper access control in the Babelfish for PostgreSQL extension versions 1.2-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish may allow remote authenticated users to elevate their privileges.
Risk Assessment
An authenticated user could gain higher privileges in the database, potentially leading to unauthorized data access or configuration changes. This violates the organization's access control model.
Recommendation
Upgrade the Babelfish for PostgreSQL extension to version 4.10, 5.6, 6.1 or later, and Aurora PostgreSQL with Babelfish clusters to the recommended versions. Also apply any pending maintenance to ensure the latest patches.
Other vulnerabilities in Babelfish for PostgreSQL
See all- CVE-2026-119924High
An out-of-bounds read in the TDS RPC procedure-name parser in the Babelfish for PostgreSQL extension (versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4) and in Amazon Aurora PostgreSQL with Babelfish. A remote authenticated user may read adjacent process memory or cause a denial of service by sending a malformed TDS RPC request to the TDS port (default 1433).
- CVE-2026-119923Critical
A heap-based buffer overflow in the TDS prelogin parser in the Babelfish for PostgreSQL extension versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish might allow remote attackers to execute arbitrary OS commands as the database process user via a specially crafted malformed TDS prelogin packet to the TDS port. This record consolidates a related NULL-pointer-dereference finding in the same prelogin parser.
