CVE-2026-29872 Details
Description
A cross-session information disclosure vulnerability exists in the awesome-llm-apps project in commit e46690f99c3f08be80a9877fab52acacf7ab8251 (2026-01-19). The affected Streamlit-based GitHub MCP Agent stores user-supplied API tokens in process-wide environment variables using os.environ without proper session isolation. Because Streamlit serves multiple concurrent users from a single Python process, credentials provided by one user remain accessible to subsequent unauthenticated users. An attacker can exploit this issue to retrieve sensitive information such as GitHub Personal Access Tokens or LLM API keys, potentially leading to unauthorized access to private resources and financial abuse.
A cross-session information disclosure vulnerability has been identified in the awesome-llm-apps project, specifically within the Streamlit-based GitHub MCP Agent. This vulnerability arises because the application stores user-provided API tokens, such as GitHub Personal Access Tokens and OpenAI API keys, in process-wide environment variables using 'os.environ', without adequate session isolation. As Streamlit operates multiple concurrent user sessions within a single Python process, credentials from one user can be accessed by subsequent unauthenticated users. This flaw allows an attacker to exploit the vulnerability and retrieve sensitive information, potentially leading to unauthorized access to private resources and financial abuse.
Do not store user credentials in global environment variables. Instead, use session-scoped storage to bind credentials strictly to individual user sessions. Clear sensitive data after use and avoid passing secrets through shared global state.
