Description

SiYuan versions before v3.7.4 fail to validate or escape annotation fields written to disk by the setFileAnnotation endpoint. Attackers can inject malicious markup into annotation fields that execute as script in the PDF renderer with full Node.js access when a user opens an annotated PDF.

CVE-2026-73053
SiYuan versions before v3.7.4 contain a cross-site scripting vulnerability in the unicode2Emoji function that fails to sanitize codepoint branch output. Attackers can craft document icons with hex-encoded markup that executes in the renderer with Node integration enabled, achieving arbitrary code execution on the host system.

CVE-2026-73052
SiYuan before v3.7.4 stores attribute-view field names without HTML escaping and interpolates them directly into option elements via innerHTML in the sort menu. Attackers can inject markup by renaming a database field to execute arbitrary JavaScript when users open the sort menu, with Node integration enabled in the desktop client enabling code execution.

CVE-2026-73050
SiYuan versions before v3.7.4 fail to validate or escape the color field in attribute-view select options, allowing stored cross-site scripting through eight unescaped render sites. Attackers can inject event-handler attributes by including quotation marks in the color value, executing arbitrary JavaScript when viewing databases containing the malicious select field.

CVE-2026-73046
SiYuan before v3.7.4 improperly restricts excessive authentication attempts in the CheckAuth() middleware. The HTTP Basic Authentication branch, which guards nearly the entire /api/* surface, accepts the workspace access code (Conf.AccessAuthCode) as the Basic Auth password but never consults the CAPTCHA/lockout gate or increments the failure counter used by the cookie/session login path. This allows unauthenticated remote attackers to brute-force the admin access code with unlimited automated requests and obtain full RoleAdministrator access to the kernel. A secondary weakness exists because the access code is compared using a non-constant-time string comparison.

CVE-2026-73044
SiYuan versions before v3.7.4 fail to validate or escape table column width values, allowing stored cross-site scripting injection into style attributes. Attackers can inject malicious payloads through the setAttrViewColWidth API that break out of style attributes and inject event handlers on every table cell, executing arbitrary code in the Electron renderer with Node integration enabled.
