CVE-2026-1243: Vulnerability in IBM Content Navigator
IBM Content Navigator versions 3. 0. 15, 3. 1. 0, and 3. 2. 0 contain a cross-site scripting (XSS) vulnerability that allows an authenticated user to inject arbitrary JavaScript code into the web user interface. This can alter the intended functionality and potentially lead to the disclosure of credentials within a trusted session. The vulnerability requires user interaction and privileges to exploit and does not impact availability. No official patch or remediation details are provided in the available data.
AI Analysis
Technical Summary
CVE-2026-1243 is a medium-severity cross-site scripting vulnerability (CWE-79) affecting IBM Content Navigator versions 3.0.15, 3.1.0, and 3.2.0. An authenticated user with limited privileges can embed arbitrary JavaScript code into the web UI, which may alter application behavior and potentially disclose credentials during a trusted session. The CVSS 3.1 base score is 5.4, reflecting network attack vector, low attack complexity, required privileges, and user interaction. The vulnerability does not affect availability and impacts confidentiality and integrity to a limited extent. No known exploits in the wild or vendor patch information is currently available.
Potential Impact
An authenticated user can exploit this vulnerability to inject malicious JavaScript code into the IBM Content Navigator web interface. This may lead to unauthorized disclosure of credentials within the context of a trusted session and modification of application functionality. The impact is limited to confidentiality and integrity, with no effect on availability. The vulnerability requires user interaction and privileges, reducing the likelihood of widespread exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until an official fix is available, restrict access to IBM Content Navigator to trusted users only and monitor for suspicious activity. Avoid granting unnecessary privileges to users to reduce exploitation risk. Do not rely on generic mitigations; follow vendor updates closely.
