Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada homeassistant-ai home assistant mcp server. Skor CVSS 3.1 4.7 (Medium) menurut NVD.

Deskripsi (NVD)

ha-mcp is a Home Assistant MCP Server. Prior to 7.0.0, the ha-mcp OAuth consent form renders user-controlled parameters via Python f-strings with no HTML escaping. An attacker who can reach the OAuth endpoint and convince the server operator to follow a crafted authorization URL could execute JavaScript in the operator's browser. This affects only users running the beta OAuth mode (ha-mcp-oauth), which is not part of the standard setup and requires explicit configuration. This vulnerability is fixed in 7.0.0.
