SiYuan Vulnerable to Stored Cross-Site Scripting (XSS) via Unrestricted SVG File Upload

SiYuan is self-hosted, open source personal knowledge management software. Prior to 3.5.4-dev2, a Stored Cross-Site Scripting (XSS) vulnerability exists in SiYuan Note. The application does not sanitize uploaded SVG files. If a user uploads and views a malicious SVG file (e.g., imported from an untrusted source), arbitrary JavaScript code is executed in the context of their authenticated session. This vulnerability is fixed in 3.5.4-dev2.

Deno node:crypto doesn't finalize cipher

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Before 2.6.0, node:crypto doesn't finalize cipher. The vulnerability allows an attacker to have infinite encryptions. This can lead to naive attempts at brute forcing, as well as more refined attacks with the goal to learn the server secrets. This vulnerability is fixed in 2.6.0.

Gradle fails to disable repositories which can expose builds to malicious artifacts

Gradle is a build automation tool, and its native-platform tool provides Java bindings for native APIs. When resolving dependencies in versions before 9.3.0, some exceptions were not treated as fatal errors and would not cause a repository to be disabled. If a build encountered one of these exceptions, Gradle would continue to the next repository in the list and potentially resolve dependencies from a different repository. If a Gradle build used an unresolvable host name, Gradle would continue to work as long as all dependencies could be resolved from another repository. An unresolvable host name could be caused by allowing a repository's domain name registration to lapse or typo-ing the real domain name. This behavior could allow an attacker to register a service under the host name used by the build and serve malicious artifacts. The attack requires the repository to be listed before others in the build configuration. Gradle has introduced a change in behavior in Gradle 9.3.0 to stop searching other repositories when encountering these errors.

Integer overflow in memalign leads to heap corruption

Passing too large an alignment to the memalign suite of functions (memalign, posix_memalign, aligned_alloc, valloc, pvalloc) in the GNU C Library version 2.30 to 2.42 may result in an integer overflow, which could consequently result in a heap corruption.

Libxml2: unbounded relaxng include recursion leading to stack overflow

A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.

Libsoup: out-of-bounds read in libsoup websocket frame processing

A flaw was found in libsoup’s WebSocket frame processing when handling incoming messages. If a non-default configuration is used where the maximum incoming payload size is unset, the library may read memory outside the intended bounds. This can cause unintended memory exposure or a crash. Applications using libsoup’s WebSocket support with this configuration may be impacted.

Libxml2: libxml2: denial of service via crafted xml catalogs

A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.

wolfSSL Python library `CERT_REQUIRED` mode fails to enforce client certificate requirement

A vulnerability in the handling of verify_mode = CERT_REQUIRED in the wolfssl Python package (wolfssl-py) causes client certificate requirements to not be fully enforced.  Because the WOLFSSL_VERIFY_FAIL_IF_NO_PEER_CERT flag was not included, the behavior effectively matched CERT_OPTIONAL: a peer certificate was verified if presented, but connections were incorrectly authenticated when no client certificate was provided.  This results in improper authentication, allowing attackers to bypass mutual TLS (mTLS) client authentication by omitting a client certificate during the TLS handshake.  The issue affects versions up to and including 5.8.2.
