Technical Summary
The vulnerability CVE-2026-14529 affects IBM WebSphere Application Server 9.0, 8.5, and Liberty versions 17.0.0.3 through 26.0.0.8 traditional when the SIP container feature (sipServlet-1.1) is enabled. It is a server-side request forgery (SSRF) vulnerability that can be exploited remotely without authentication (AV:N/AC:L/PR:N/UI:N). The impact includes high confidentiality and integrity loss with low availability impact (C:H/I:H/A:L). The vulnerability is categorized under CWE-306, indicating insufficient authentication. There is no vendor advisory or patch information provided, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation of this SSRF vulnerability can lead to high confidentiality and integrity impacts, potentially allowing attackers to access or manipulate internal resources or data. Availability impact is low. The vulnerability does not require user interaction or privileges to exploit, increasing its risk profile.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider disabling the SIP container feature (sipServlet-1.1) if it is not required, or restrict network access to the affected server to limit exposure.
