## What is CVE-2025-59053?

CVE-2025-59053 is a critical cross-site scripting vulnerability in moeru-ai airi, published on 11 Sep 2025. 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

AIRI is a self-hosted, artificial intelligence based Grok Companion. In v0.7.2-beta.2 in the `packages/stage-ui/src/components/MarkdownRenderer.vue` path, the Markdown content is processed using the useMarkdown composable, and the processed HTML is rendered directly into the DOM using v-html. An attacker creates a card file containing malicious HTML/JavaScript, then simply processes it using the highlightTagToHtml function (which simply replaces template tags without HTML escaping), and then directly renders it using v-html, leading to cross-site scripting (XSS). The project also exposes the Tauri API, which can be called from the frontend. The MCP plugin exposes a command execution interface function in `crates/tauri-plugin-mcp/src/lib.rs`. This allows arbitrary command execution. `connect_server` directly passes the user-supplied `command` and `args` parameters to `Command::new(command).args(args)` without any input validation or whitelisting. Thus, the previous XSS exploit could achieve command execution through this interface. v0.7.2-beta.3 fixes the issue.

Weakness: CWE-94 (Improper Control of Generation of Code)

Check this codebase for CVE-2025-59053 and fix it if it is affected.

What it is: CVE-2025-59053 is a critical cross-site scripting vulnerability in moeru-ai airi, published on 11 Sep 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-59053 exists.

Affected product: moeru-ai airi. 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.
