Streamlit

Streamlit is a data oriented application development framework for python. Streamlit Open Source versions prior to 1.54.0 running on Windows hosts have an unauthenticated Server-Side Request Forgery (SSRF) vulnerability. The vulnerability arises from improper validation of attacker-supplied filesystem paths. In certain code paths, including within the `ComponentRequestHandler`, filesystem paths are resolved using `os.path.realpath()` or `Path.resolve()` before sufficient validation occurs. On Windows systems, supplying a malicious UNC path (e.g., `\\attacker-controlled-host\share`) can cause the Streamlit server to initiate outbound SMB connections over port 445. When Windows attempts to authenticate to the remote SMB server, NTLMv2 challenge-response credentials of the Windows user running the Streamlit process may be transmitted. This behavior may allow an attacker to perform NTLM relay attacks against other internal services and/or identify internally reachable SMB hosts via timing analysis. The vulnerability has been fixed in Streamlit Open Source version 1.54.0.

A vulnerability has been found in Streamlit up to 1.53.0. Impacted is an unknown function in the library lib/streamlit/runtime/caching/hashing.py of the component Palette Handler. Such manipulation leads to use of weak hash. Local access is required to approach this attack. The attack requires a high level of complexity. The exploitability is considered difficult. The exploit has been disclosed to the public and may be used. The pull request to fix this issue awaits acceptance.

Streamlit is a data oriented application development framework for python. Snowflake Streamlit open source addressed a security vulnerability via the static file sharing feature. Users of hosted Streamlit app(s) on Windows were vulnerable to a path traversal vulnerability when the static file sharing feature is enabled. An attacker could utilize the vulnerability to leak the password hash of the Windows user running Streamlit. The vulnerability was patched on Jul 25, 2024, as part of Streamlit open source version 1.37.0. The vulnerability only affects Windows.

Streamlit, software for turning data scripts into web applications, had a cross-site scripting (XSS) vulnerability in versions 0.63.0 through 0.80.0. 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 XSS. Version 0.81.0 contains a patch for this vulnerability.

Streamlit is a data oriented application development framework for python. Users hosting Streamlit app(s) that use custom components are vulnerable to a directory traversal attack that could leak data from their web server file-system such as: server logs, world readable files, and potentially other sensitive information. An attacker can craft a malicious URL with file paths and the streamlit server would process that URL and return the contents of that file. This issue has been resolved in version 1.11.1. Users are advised to upgrade. There are no known workarounds for this issue.
