CVE-2026-15280Network attack vector

Unauthenticated information disclosure via path-segment injection

Published Jul 28, 2026 · Updated Jul 28, 2026

Path traversal in IBM WebSphere Application Server Liberty 17.0.0.3 through 26.0.0.8 allows remote attackers to access restricted information. The ND Collective Controller routing mechanism accepts injected path segments without adequately limiting the resolved path, but IBM has not disclosed the affected code locus or request format. Exposure requires the collectiveController-1.0 feature to be enabled; the published impact is unauthorized information disclosure only.
