## What is CVE-2026-17497?

CVE-2026-17497 is a high-severity command injection vulnerability in codexu NoteGen, published on 26 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

NoteGen before 0.32.0 grants the Tauri shell plugin shell:allow-execute capability for bash, python, and python3 with arbitrary arguments in the default desktop capabilities. JavaScript running in the application webview can therefore invoke plugin:shell|execute to run attacker-controlled operating system commands with the privileges of the NoteGen process. In combination with script execution in the webview (for example via chat XSS), this enables full remote code execution on the user's machine.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command), CWE-276 (Incorrect Default Permissions), CWE-1249 (Application-Level Admin Tool with Inconsistent View of Underlying Operating System)

What it is: CVE-2026-17497 is a high-severity command injection vulnerability in codexu NoteGen, published on 26 Jul 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-17497 in the wild and no public exploit code.

Affected product: codexu NoteGen. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
