EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.6 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 59% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
