# djust: Arbitrary absolute-path file read in the find_handlers_for_template MCP tool Advisory record · `GHSA-r57g-mc79-8hj2` - **Identifiers:** `GHSA-r57g-mc79-8hj2` · `CVE-2026-113731` - **State:** Confirmed - **Severity:** CVSS 3.3 Low - **Critical:** No - **Weakness (CWE):** [CWE-22](https://cwe.mitre.org/data/definitions/22.html) - **Tags:** [Path traversal](https://agentprime.io/advisories/tag/path-traversal.md) - **Published:** 21 Oct 2026 - **Updated:** 21 Oct 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 21 Oct 2026, 17:21 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `djust` (PyPI): affected `>=0.9.0, <1.0.10 || >=1.1.0, <1.1.7 || >=1.2.0.dev0, <1.2.4 || >=1.3.0.dev0, <1.3.0rc8`; fixed in `1.0.10`, `1.1.7`, `1.2.4`, `1.3.0rc8` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > The djust MCP tool find_handlers_for_template, in versions 0.9.0 to before 1.0.10, 1.1.0 to before 1.1.7, 1.2.0 to before 1.2.4, and 1.3.0.dev0 to before 1.3.0rc8, reads any absolute path passed as template_path without confining it to project or template directories. An MCP client able to call the tool can learn whether any readable file exists at a given path and receive the substrings matching dj-event attribute patterns from it, but not the full file contents. Upgrade to 1.0.10, 1.1.7, 1.2.4, 1.3.0rc8 or later. Until then, pass only logical template names to the tool.

Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation - 3.3 Low, CVSS 3.1: `CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N`, from CNA (GitHub_M) - **CISA KEV:** Not listed. - **EPSS:** 0.0019, the 8th percentile, on 7 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 14:08 UTC: First seen by agentprime - 31 Oct 2026, 14:08 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-r57g-mc79-8hj2) ## Sources - [GitHub Advisory Database: GHSA-r57g-mc79-8hj2](https://github.com/advisories/GHSA-r57g-mc79-8hj2) - [OSV: GHSA-r57g-mc79-8hj2](https://osv.dev/vulnerability/GHSA-r57g-mc79-8hj2) - - - - - - - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
