5.8CVE-2026-73609: Missing Authorization in SiYuan Note getBookmarkLabels Endpoint
An information disclosure vulnerability (CWE-862) in the SiYuan Note platform before version v3.7.4 allows anonymous or unprivileged readers to obtain a complete list of bookmark labels globally across all workspaces and notebooks by querying the `/api/attr/getBookmarkLabels` API endpoint.

5.3Missing publish-access check on getAttributeViewSearchTarget endpoint exposes database row content to unauthorized readers
An authorization bypass and information leakage vulnerability exists in the SiYuan database module. Unauthenticated users can query the getAttributeViewSearchTarget API endpoint using target block identifiers to extract private content.

9.8CVE-2026-76504: Unauthenticated Authentication Bypass in Cisco Catalyst SD-WAN Manager
CVE-2026-76504 is a critical vulnerability in the web-based management console of Cisco Catalyst SD-WAN Manager. Due to improper normalization and handling of hex/percent-encoded sequences (CWE-177) within incoming request URIs, remote, unauthenticated attackers can bypass administrative authentication controls. Successful exploitation permits full remote administrative command execution on the SD-WAN management plane, threatening the integrity and availability of the managed network fabric.

6.9CVE-2026-73606: Authorization Bypass and Information Disclosure in SiYuan /api/block/getRefIDs Endpoint
An authorization bypass and information disclosure vulnerability in the SiYuan personal knowledge management system before version 3.7.4 allows unauthenticated attackers to query block relationship metadata from password-protected documents.

6.9CVE-2026-73605: Path Traversal and File Existence Oracle via getUniqueFilename Endpoint in SiYuan
An authorization bypass and path traversal vulnerability exists in the SiYuan knowledge workspace platform. The vulnerability is located in the '/api/file/getUniqueFilename' endpoint inside the 'github.com/siyuan-note/siyuan/kernel' package. Under default configurations, this route is exposed to users who satisfy basic authentication middleware checks, which includes anonymous readers in publish mode. By supplying unvalidated absolute paths, remote attackers can verify the existence of files and directories across the host operating system, establishing a high-fidelity file existence oracle.

8.2CVE-2026-102990: Regular Expression Denial of Service in basic-ftp Directory Parsing
A highly critical Regular Expression Denial of Service (ReDoS) vulnerability in basic-ftp, an FTP client library for Node.js. In versions prior to 6.2.1, a malicious or compromised FTP server can exploit this vulnerability to force the FTP client to consume quadratic CPU time during directory parsing. This issue blocks the single-threaded Node.js event loop, freezing the application process and leading to a complete Denial of Service (DoS).

6.5CVE-2026-102821: Unbounded Memory Exhaustion via CHANNEL_OPEN Flood in russh
An uncontrolled resource consumption vulnerability in the russh library allows remote authenticated attackers to exhaust server memory (heap) by flooding channel open requests during a stalled key re-exchange (rekeying) process, causing a denial of service via Out-of-Memory (OOM) termination.

6.2CVE-2026-102820: Out-of-Bounds Read and Excessive Memory Allocation in russh pageant
A critical memory handling vulnerability exists in the pageant crate, a workspace component of the Rust-based russh SSH client library, during communication with the PuTTY Pageant SSH agent on Windows systems. Prior to version 0.2.3, the library's shared memory parsing logic blindly trusted a peer-controlled, 32-bit big-endian response length field. This allows local attackers running within the same user session to trigger out-of-bounds reads or execute an out-of-memory crash of the client application.

7.5CVE-2026-84428: Schema Validation Bypass in Fastify Header Normalization
A validation bypass vulnerability exists in Fastify web framework prior to version 5.12.2. The flaw stems from shallow normalization of header validation schemas, which fails to lowercase nested or conditional schema rules (like JSON Schema dependencies or dependentRequired) defined in mixed or canonical casing. Consequently, because Node.js normalizes incoming HTTP request headers to lowercase, the compiled validator fails to match these headers against the un-normalized mixed-case schema triggers, silently skipping conditional checks and allowing unauthenticated attackers to bypass authorization or security headers.

7.5CVE-2026-84469: Request Validation Bypass in Fastify via Loose Boolean Schema Evaluation
CVE-2026-84469 is a high-severity request validation bypass vulnerability in the Fastify Node.js web framework. In versions prior to 5.12.2, Fastify uses loose truthiness checks to decide whether to compile request schemas. When a component (such as the body) is explicitly configured with a boolean 'false' schema—which under JSON Schema Draft 7 acts as a 'deny-all' constraint—Fastify's internal logic evaluates this as a falsy value and skips compilation entirely. This allows unauthenticated remote attackers to send arbitrary payloads to these endpoints, bypassing validation checks and directly executing backend route handlers.

7.5CVE-2026-76169: Authentication Bypass and Encapsulation Violation via Malformed URL Routing Fallback in Fastify
An authentication bypass vulnerability in the Fastify web framework allows remote attackers to access private custom not-found handlers by submitting requests with malformed URLs. This bypasses the typical request lifecycle and its associated authorization hooks.

8.1CVE-2026-84504: Schema Validation Bypass via Async Validation Result Collision in Fastify
An API contract mismatch in the Fastify web framework allows remote attackers to bypass schema validation when asynchronous schema validators are used. When a route uses async validation, the validator resolves with the raw request body. If the body contains a root-level key named 'value', the validation runner interprets this as a synchronous wrapper envelope, extracting and promoting the unvalidated nested content to the root level of request.body.
