Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-5485 is an OS command injection vulnerability (CWE-78) in the browser-based authentication component of the Amazon Athena ODBC driver for Linux, affecting versions prior to 2.0.5.1. The flaw arises when the driver processes specially crafted connection parameters during a local user-initiated connection, potentially enabling arbitrary code execution. Published on April 3, 2026, it carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high confidentiality, integrity, and availability impacts with local access required.
A local threat actor can exploit this vulnerability by tricking a user into initiating a connection with malicious parameters, such as through a controlled data source or configuration file. No privileges are needed (PR:N), but user interaction is required (UI:R), typically involving launching the driver in a browser-based authentication flow. Successful exploitation allows arbitrary OS command execution with the privileges of the local user running the driver.
AWS advisories recommend upgrading to Amazon Athena ODBC driver version 2.0.5.1 or later to remediate the issue, with release notes and updated Linux packages available via official download links. The AWS security bulletin details the vulnerability and patch availability.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
