CVE-2026-108159
AstronRPA through 1.1.6 RCE via Smart-Component Chat XSS and IPC Bridge
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.
