## What is CVE-2026-108159?

CVE-2026-108159 is a high-severity cross-site scripting vulnerability in iflytek astron-rpa, published on 9 Oct 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

AstronRPA through 1.1.6 contains a cross-site scripting vulnerability in the desktop client's smart-component chat that allows remote attackers to execute OS commands by abusing unsanitized LLM output rendered via v-html. Attackers can embed prompt-injection content in a web page so the model emits HTML event handlers invoking the unrestricted open-path IPC handler with shell metacharacters, executing commands as the desktop user.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
