DevikaAI Stored Cross-Site Scripting
MediumSynopsis
A Stored Cross-Site Scripting exists in the current version of DevikaAI (June 8 - commit 6acce21).
This commit adds the use of DOMPurify (an HTML sanitization library) to "ui/src/lib/components/MessageInput.svelte".
As indicated by the file name, only user entries are filtered, thus avoiding "raw" payload injection.
However, it is possible to ask the model to decode an encoded character string (Base64 for example) which will be interpreted when displayed.
Depending on the LLM model and prompt used, a stored cross-site scripting attack may be possible.
