Local privilege escalation via sudoers parameter abuse
Published Sep 8, 2026 · Updated Sep 8, 2026
Improper privilege management in AlgoSec Horizon Security Analyzer A33.10, A33.20, and A33.30 allows local users to elevate privileges. A sudoers entry authorizes a command without constraining attacker-controlled parameters, allowing arguments to be injected into privileged execution. Exploitation requires local command-line access to a 64-bit Linux installation and grants the authority of the approved command.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=A33.10 (up to build 300)
- Affected versionversion=A33.20 (up to build 170)
- Affected versionversion=A33.30 (up to build 110)
