Path Traversal in Djust-Org Djust

CVE-2026-113731

djust provides Phoenix LiveView-style reactive server-side rendering for Django with Rust-powered performance. From 0.9.0 until 1.0.10, 1.1.7, 1.2.4, and 1.3.0rc8, the find_handlers_for_template MCP tool in python/djust/mcp/server.py accepts an existing absolute template_path and reads it without restricting the resolved path to the project or configured template directories. A local MCP client can use the tool as a file existence and readability oracle and can obtain substrings that match the tool's dj-click, dj-submit, dj-change, dj-input, dj-keydown, or dj-keyup attribute pattern from files readable by the djust process. The maintainer assessment states that the MCP server communicates over local stdio as the same operating-system user and has no network listener, and the tool does not return arbitrary raw file contents. This issue is fixed in versions 1.0.10, 1.1.7, 1.2.4, and 1.3.0rc8.
