Technical description

SiYuan versions before v3.7.4 fail to apply publish-access filtering to the getAttributeViewKeysByID endpoint, allowing authenticated readers to retrieve complete database column schemas including descriptions, select vocabularies, and template expressions. Additionally, getBlockDefIDsByRefText and getBlockRelevantIDs endpoints enumerate workspace-wide block IDs without publish scoping, enabling attackers to discover valid block identifiers across publish boundaries and access content from hidden or password-protected documents.

CVE-2026-47718—

—

———FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. When `secureEnabled=true`, FUXA `1.3.0-2773` still allows guest and invalid-token requests to read project, alarms, and scheduler APIs. Version 1.3.1 fixes this issue.4h CVE-2026-733267.6 HIG

—

———CamaleonCMS contains a missing authorization vulnerability that allows any authenticated low-privileged user to access and modify plugin settings by reaching four unprotected plugin-administration endpoints without administrator-level authorization. Attackers can manipulate plugin configuration parameters at runtime across the attack, front_cache, cama_meta_tag, and cama_contact_form plugins to alter cached page behavior, modify public meta-tag output, or reconfigure contact forms, enabling account takeover when chained with stored cross-site scripting through the contact form's before_html field.7h CVE-2026-728085.8 MED

—

———SiYuan versions up to and including v3.7.2 (fixed in v3.7.4) contain an information disclosure vulnerability in the /api/asset/getFileAnnotation endpoint, which returns .sya PDF-annotation file content without a publish-access check. Because the endpoint is gated only by CheckAuth (unlike the /assets/* route, which enforces publish access and password), an anonymous reader (when publish authentication is disabled) or any publish RoleReader who knows an asset path can read the private PDF annotations (highlights and notes) of publish-forbidden, password-protected, or unpublished documents. The issue is limited to non-encrypted notebooks; encrypted-box annotations are not exposed.7h CVE-2026-728065.8 MED

—

———SiYuan versions before v3.7.4 contain an authentication bypass vulnerability in the FilterViewByPublishAccess filter that fails to check publish password protection when rendering attribute views and database rows. Unauthenticated readers can access password-protected document rows including titles, block IDs, and column values by calling renderAttributeView without supplying the required password.7h CVE-2026-728055.8 MED

—

———SiYuan versions before v3.7.4 fail to enforce publish-access checks on getBlockBreadcrumb, getRefText, and getBlockTreeInfos endpoints, allowing disclosure of protected document content and metadata. Anonymous readers or publish RoleReader accounts can retrieve document titles, ancestor block content snippets, reference text, and path metadata for publish-forbidden or password-protected documents by supplying block IDs.7h CVE-2026-728035.8 MED

—

———SiYuan versions before v3.7.4 fail to enforce publish-access checks in the getBlockAttrs and batchGetBlockAttrs endpoints. Attackers can retrieve block attributes including names, aliases, memos, and custom fields from protected documents by sending POST requests with block IDs.6h
