0 CVE-2026-23847 is a reflected cross-site scripting (XSS) vulnerability in SiYuan, a personal knowledge management system, affecting versions prior to 3.5.4. The flaw exists in the /api/icon/getDynamicIcon endpoint, which generates SVG images for text icons by inserting user-supplied content directly into an SVG <text> tag without proper XML escaping. Because the response is served with the image/svg+xml content type, attackers can inject malicious JavaScript by breaking the XML structure, leading to script execution in the victim's browser. The vulnerability requires no authentication but does require user interaction to trigger the malicious payload. The CVSS 4.0 score is low (2.1), reflecting limited impact and ease of exploitation. The issue was patched in version 3. Join the discussion | CVE Database V5 | 01/19/2026, 19:46:08 UTC Added: 01/19/2026, 19:50:56 UTC |
