3.1 Description

On April 20, 2021, Streamlit was informed via our support forum about a XSS vulnerability in the open source library. We fixed and merged a patch remediating the vulnerability on April 21st, 2021. The issue was determined to be in the moderate severity range with a maximum CVSSv3 base score of 5.9

3.2 Scenarios and attack vector(s)

Users of hosted Streamlit app(s) were vulnerable to a reflected XSS vulnerability. An attacker could craft a malicious URL with Javascript payloads to a Streamlit app. The attacker could then trick the user into visiting the malicious URL and, if successful, the server would render the malicious javascript payload as-is, leading to an XSS.
