Summary

CVE-2026-11595 is a medium-severity Path Traversal (CWE-22) vulnerability in Ibm Websphere Application Server. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 48th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

IBM WebSphere Application Server 9.0, and 8.5 could allow a remote attacker to obtain sensitive information from the administrative console's integrated help system.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
Why these techniques?

Path traversal in remote admin console enables file read for sensitive data disclosure.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Validates pathnames in help-system requests to block traversal sequences that would otherwise expose sensitive files.

prevent

Enforces authorization checks on every access to administrative console resources, denying traversal-based reads outside permitted directories.

prevent

Restricts the privileges of the WebSphere process and help-system component so that even a successful traversal yields minimal sensitive data.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

detects

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
