Details

Elvish vulnerable to remote code execution via the web UI backend ### Impact Elvish's backend for the experimental web UI (started by `elvish -web`) hosts an endpoint that allows executing the code sent from the web UI. The backend does not check the origin of requests correctly. As a result, if the user has the web UI backend open and visits a compromised or malicious website, the website can send arbitrary code to the endpoint in localhost. ### Patches All Elvish releases since 0.14.0 no longer include the experimental web UI, although it is still possible for the user to build a version from source that includes it. The issue can be patched for previous versions by removing the web UI (found in web, pkg/web or pkg/prog/web, depending on the exact version). ### Workarounds Do not use the experimental web UI. ### For more information If you have any questions or comments about this advisory, please email xiaqqaix@gmail.com.
