AnythingLLM has a Streaming Phase XSS to RCE via LLM Response Injection

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. In 1.11.1 and earlier, AnythingLLM Desktop contains a Streaming Phase XSS vulnerability in the chat rendering pipeline that escalates to Remote Code Execution on the host OS due to insecure Electron configuration. This works with default settings and requires no user interaction beyond normal chat usage. The custom markdown-it image renderer in frontend/src/utils/chat/markdown.js interpolates token.content directly into the alt attribute without HTML entity escaping. The PromptReply component renders this output via dangerouslySetInnerHTML without DOMPurify sanitization — unlike HistoricalMessage which correctly applies DOMPurify.sanitize().

AnythingLLM 跨站脚本漏洞

AnythingLLM是Mintplex开源的一个一体化AI应用程序。 AnythingLLM 1.11.1及之前版本存在跨站脚本漏洞，该漏洞源于聊天渲染管道中存在流式阶段跨站脚本，由于不安全的Electron配置，可能升级为对主机操作系统的远程代码执行，前端自定义markdown-it图像渲染器将token.content直接插入alt属性而未进行HTML实体转义。
