Dask distributed Vulnerable to Remote Code Execution via Jupyter Proxy and Dashboard

Dask distributed is a distributed task scheduler for Dask. Prior to 2026.1.0, when Jupyter Lab, jupyter-server-proxy, and Dask distributed are all run together, it is possible to craft a URL which will result in code being executed by Jupyter due to a cross-side-scripting (XSS) bug in the Dask dashboard. It is possible for attackers to craft a phishing URL that assumes Jupyter Lab and Dask may be running on localhost and using default ports. If a user clicks on the malicious link it will open an error page in the Dask Dashboard via the Jupyter Lab proxy which will cause code to be executed by the default Jupyter Python kernel. This vulnerability is fixed in 2026.1.0.

FreeRDP has a heap-buffer-overflow in audin_process_formats

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a malicious RDP server can trigger a heap-buffer-overflow write in the FreeRDP client when processing Audio Input (AUDIN) format lists. audin_process_formats reuses callback->formats_count across multiple MSG_SNDIN_FORMATS PDUs and writes past the newly allocated formats array, causing memory corruption and a crash. This vulnerability is fixed in 3.20.1.

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.

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.

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.
