CVE-2026-18106: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to improper validation of user-supplied path input.
AI Analysis
Technical Summary
CVE-2026-18106 is a path traversal vulnerability in IBM i versions 7.3 through 7.6. It arises from improper validation of user-supplied pathname input, which could allow a remote attacker with authentication privileges to access sensitive information outside of intended directories. The vulnerability does not require user interaction beyond authentication and has a low complexity attack vector. No integrity or availability impact is indicated.
Potential Impact
An authenticated remote attacker could exploit this vulnerability to obtain sensitive information by bypassing directory restrictions. The confidentiality impact is limited to information disclosure; there is no indication of integrity or availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been published. Until a patch is available, restrict access to trusted users and monitor for suspicious activity related to path traversal attempts.
