## Affected

- innocommerce InnoShop: 0.9.2 only

## Description

InnoShop 0.9.2 contains a local file disclosure vulnerability that allows authenticated administrators with files_create permission to read server files by abusing the AI Core MCP file_upload tool's source argument. Attackers can supply file:// or php:// stream wrappers passed to file_get_contents(), storing contents on the public media disk to expose the .env file with APP_KEY and database credentials.
