Packages

Ecosystem	Package	Affected	Fixed in
Packagist	appwrite/server-ce	>= 0.5.0, < 0.12.2	0.12.2

Details

As written in the advisory (Markdown source, shown as plain text).

The ACME-challenge endpoint in Appwrite 0.5.0 through 0.12.x before 0.12.2 allows remote attackers to read arbitrary local files via ../ directory traversal. In order to be vulnerable, `APP_STORAGE_CERTIFICATES/.well-known/acme-challenge` must exist on disk. (This pathname is automatically created if the user chooses to install Let's Encrypt certificates via Appwrite.)
