CVE-2026-17466

Summary

IBM Optim versions 1.0.0 through 1.2.0 contain a path traversal vulnerability (CWE-22) that allows an authenticated remote attacker to read sensitive files outside intended directories due to insufficient input validation on file paths.

Exploitability

Exploitation requires valid authentication credentials and the ability to submit crafted path inputs to vulnerable endpoints, with no additional user interaction or complex conditions needed.

Blast radius

Successful exploitation could lead to exposure of sensitive configuration data, credentials, or internal system files, potentially enabling further compromise such as lateral movement or privilege escalation.

Detection

Defenders should monitor web server access logs for requests containing encoded or unencoded path traversal sequences (e.g., '../', '%2e%2e/', '..%2f') in file-related parameters, especially when combined with authenticated sessions and non-standard file extensions or paths.

Prioritized remediation

Upgrade IBM Optim to version 1.3.0 or later, as this is the first fixed release addressing CVE-2026-17466.
