CVE-2024-27287 is a stored cross-site scripting vulnerability in the ESPHome dashboard component's edit configuration file API. In affected versions starting at 2023.12.9 and before 2024.2.2, the /edit endpoint serves user-controlled configuration file content as "Content-Type: text/html; charset=UTF-8" without proper sanitization. A remote authenticated attacker can use a POST request to /edit to write arbitrary JavaScript into a configuration file, because the configuration parameter allows the attacker to specify the file to write. When another authenticated user later visits /edit?configuration=[malicious file], the injected script executes in the context of the ESPHome dashboard. The issue affects both command line installations and the Home Assistant add-on. The provided context also notes that cookies were not correctly secured, which can facilitate session cookie exfiltration.
