IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote authenticated attacker to obtain sensitive information due to improper limitation of a pathname to a restricted directory.
AI Analysis
Technical Summary
CVE-2026-18554 affects IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6. The vulnerability arises from improper restriction of pathnames, enabling a remote attacker with authentication to access sensitive information outside intended directories. This is a directory traversal vulnerability (CWE-22). The CVSS 3.1 base score is 7.5, reflecting high confidentiality impact without integrity or availability impact. No known exploits are reported in the wild, and no patch or remediation details are currently available.
Potential Impact
A remote attacker who is authenticated can exploit this vulnerability to access sensitive information that should be restricted. The confidentiality impact is high, but integrity and availability are not affected. This could lead to unauthorized disclosure of sensitive data within the affected IBM Db2 Mirror for i environments.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit access to trusted authenticated users only and monitor for unusual access patterns related to pathname usage. Follow IBM's security advisories for updates on patches or mitigations.
