CVE-2026-63376: Prototype Pollution via Path Desynchronization in toml-node

A prototype pollution vulnerability exists in the toml-node library (by BinaryMuse) in versions prior to 4.1.2. The flaw arises from inconsistent internal tracking of parsed paths (comma-joined vs. dot-joined serialization) combined with lack of object ownership validation during recursive dictionary descent (scalar descent). This allows unauthenticated remote attackers to modify base object structures by crafting malicious TOML documents containing conflicting duplicate table paths or nested references.

CVE-2026-69083: Unauthenticated SQL Injection and SQL Command Execution in SiYuan Full-Text Search API

An unauthenticated SQL injection and SQL execution vulnerability in SiYuan allows remote attackers to compromise the integrity and confidentiality of the asset database. The flaw exists due to string concatenation in regular expression searches and a complete lack of authorization checks on raw SQL querying pathways under default configurations. Attackers can leverage this vulnerability to exfiltrate database contents, manipulate index records, or access cross-notebook contents without any valid credentials.

CVE-2026-68587: Broken Access Control in SiYuan Note Transaction Endpoints

CVE-2026-68587 is a critical authorization bypass vulnerability in SiYuan, an open-source personal knowledge management workspace. When deployed in publish mode, specific transaction endpoints fail to perform administrative role validation. This omission enables unauthenticated remote readers to retrieve the rendered Document Object Model (DOM) of publish-disabled (private) documents by supplying a target heading block identifier. Upgrading to version v3.7.3 or later resolves this issue by applying appropriate routing middleware constraints.

CVE-2026-68586: Missing Authorization in SiYuan Backlink Content Endpoints Allows Information Disclosure

SiYuan is a privacy-first personal knowledge management system. In versions prior to v3.7.3, the application fails to apply publish-access filters to the getBacklinkDoc and getBackmentionDoc content endpoints (/api/ref/getBacklinkDoc and /api/ref/getBackmentionDoc). While the corresponding backlink list endpoints correctly filter out publish-forbidden documents, the content endpoints, which are only gated by high-level route authorization checks via CheckAuth, do not. Consequently, a user with low-privilege read access, or an anonymous reader when publish Basic Auth is disabled, can directly invoke these endpoints using a known publish-forbidden document's ID to retrieve its rendered DOM content or determine whether it references a specific target block.

CVE-2026-68585: Metadata Disclosure via Missing Authorization in SiYuan API

A metadata disclosure vulnerability exists in SiYuan prior to version v3.7.3. The /api/block/getBlockInfo endpoint fails to validate authorization boundaries in publish mode, allowing anonymous readers to access private document metadata.

CVE-2026-72812: Broken Access Control and SQL Injection in SiYuan

A critical authorization bypass vulnerability exists in SiYuan personal knowledge management system before v3.7.4. The /api/ref/refreshBacklink endpoint lacks administrative role verification, enabling unauthenticated users to initiate database transactions and disk operations. When combined with an unsafe SQL generation pattern in nested backlink queries, an attacker can exploit a secondary SQL injection vulnerability to compromise local databases or cause denial-of-service conditions.

CVE-2026-72811: Remote SQL Injection in SiYuan Backlink and Mention Search Engine

A critical SQL Injection vulnerability exists in the SiYuan note-taking application (versions <= v3.7.2) due to improper neutralization of single quotes within the backlink and mention search queries. Because the application constructs SQLite Full Text Search (FTS) queries via direct string concatenation and uses a database driver that supports stacked query statements, remote unauthenticated attackers can execute arbitrary SQL commands on the master database, compromising all hosted notebooks. This issue has been fully remediated in version v3.7.4.

CVE-2026-72810: Publish-Boundary Bypass and Real-Time Data Leakage via WebSocket Session Pollution in SiYuan

CVE-2026-72810 is a critical publish-boundary bypass vulnerability in the SiYuan personal knowledge management system before version 3.7.4. The flaw lies in the backend real-time WebSocket broadcast mechanism. When configured in public publish mode, the system fails to differentiate between unauthenticated public reader sessions and authorized administrative sessions within its global connection pool. This architectural oversight allows unauthenticated remote attackers connecting to the public WebSocket endpoint on port 6808 to passively receive real-time, raw workspace modification events, including keystroke logs, block updates, and content from protected or forbidden documents.

CVE-2026-72809: Authentication Bypass in SiYuan via Localhost Trust Spoofing

An authentication bypass vulnerability exists in the SiYuan personal knowledge management system (versions <= v3.7.2). The flaw occurs because the kernel's authorization validation handler trusts loopback connection origins blindly, allowing remote network attackers to gain administrative privileges via an exposed local reverse proxy.

CVE-2026-72808: Unauthorized PDF Annotation Access in SiYuan Knowledge Management System

An information disclosure vulnerability in the SiYuan knowledge management system versions up to and including v3.7.2 allows remote unauthorized attackers to retrieve PDF annotations via the /api/asset/getFileAnnotation endpoint due to missing authorization checks.

CVE-2026-72807: Second-Order SQL Injection via Attribute View Templates in SiYuan

CVE-2026-72807 is a second-order SQL injection vulnerability in SiYuan versions prior to v3.7.4. It resides in the dynamic evaluation of Attribute View (AV) template columns, which expose unsafe template functions. An attacker can exploit this by distributing a malicious SiYuan package that executes arbitrary SQL queries on the victim's local database.

An authorization bypass vulnerability in SiYuan prior to v3.7.4 allows unauthenticated remote attackers to access rows, block IDs, and custom attributes of password-protected documents via the attribute view rendering endpoint.
