Impact
Authenticated attackers can compromise data and tamper with settings across different servers sharing the same install directory. They need low-privilege network access to one of the co-located server instances first.
Root cause
The shared installation directory lacks sufficient access control isolation between distinct server instances.
Affected systems
IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.10
CVSS v3.1 · CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N
Fix & remediation
Upgrade to a fixed release newer than 26.0.0.10 when available, or isolate individual server instances into separate, dedicated installation directories.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
