AI Analysis
Technical Summary
CVE-2026-48910 is a medium severity XSS vulnerability (CWE-80) in Apache JSPWiki affecting versions up to 2.12.3. The vulnerability arises from improper sanitization of script-related HTML tags during markdown rendering error handling, enabling attackers to inject and execute arbitrary JavaScript in users' browsers. This could lead to disclosure of sensitive information. The vendor has addressed this issue in Apache JSPWiki version 2.12.4.
Potential Impact
Successful exploitation allows an attacker to execute JavaScript in the context of the victim's browser, potentially leading to theft of sensitive information accessible to the browser. There is no indication of impact on integrity or availability. The CVSS v3.1 base score is 6.5 (medium), reflecting network attack vector, low complexity, no privileges required, user interaction required, unchanged scope, high confidentiality impact, and no integrity or availability impact.
Mitigation Recommendations
Users should upgrade Apache JSPWiki to version 2.12.4 or later to remediate this vulnerability. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory stating the fix is included in version 2.12.4.
