Detailsinfo

A vulnerability, which was classified as problematic, has been found in moeru-ai airi 0.7.2-beta.2. Affected by this issue is the function highlightTagToHtml in the library crates/tauri-plugin-mcp/src/lib.rs of the file packages/stage-ui/src/components/MarkdownRenderer.vue. The manipulation with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-59053 since 09/08/2025. The exploitation is known to be easy. The attack may be launched remotely.
