## Technical details

CVE-2026-17181 is a path traversal vulnerability (CWE-22) in the IBM Db2 Mirror for i GUI that fails to properly validate and restrict file paths during write operations. The vulnerability is exploitable remotely without authentication (AV:N, PR:N) and requires no user interaction, allowing an attacker to construct malicious path parameters with directory traversal sequences (e.g., "../../../") to write files outside the intended restricted directory. A successful exploit could allow the attacker to overwrite critical files, inject malicious code, or degrade system availability. Patches addressing this vulnerability are available from IBM.
