CVE-2026-28814: Arbitrary Wiki Markup rendering due to lack of authentication in Apache Software Foundation Apache JSPWiki
CVE-2026-28814 is a high-severity vulnerability in Apache JSPWiki up to version 2.12.3 that allows arbitrary Wiki Markup rendering due to lack of authentication. This flaw enables an attacker to access sensitive data stored in JSPWiki variables without requiring any privileges. The issue is resolved in versions 2.12.4 and 3.0.0 by introducing proper authentication controls.
AI Analysis
Technical Summary
Apache JSPWiki versions prior to 2.12.4 contain a vulnerability (CVE-2026-28814) where the absence of authentication allows attackers to render arbitrary Wiki Markup. This unauthorized rendering capability can be exploited to obtain sensitive information stored within JSPWiki variables. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function). The CVSS v3.1 base score is 7.5, reflecting a network attack vector with no privileges required and no user interaction, resulting in high confidentiality impact but no integrity or availability impact. Upgrading to Apache JSPWiki 2.12.4 or 3.0.0 mitigates this issue.
Potential Impact
An unauthenticated attacker can exploit this vulnerability remotely to render arbitrary Wiki Markup, leading to disclosure of sensitive data stored in JSPWiki variables. This compromises confidentiality but does not affect integrity or availability of the system.
Mitigation Recommendations
Users should upgrade Apache JSPWiki to version 2.12.4 or later, or to version 3.0.0, where this vulnerability is fixed. Patch status is confirmed by the vendor's recommendation to upgrade. No other mitigation or temporary workaround is indicated.
