CVE-2024-47180 Information

Description

Shields.io is a service for concise consistent and legible badges in SVG and raster format. Shields.io and users self-hosting their own instance of shields using version < server-2024-09-25 are vulnerable to a remote execution vulnerability via the JSONPath library used by the Dynamic JSON/Toml/Yaml badges. This vulnerability would allow any user with access to make a request to a URL on the instance to the ability to execute code by crafting a malicious JSONPath expression. All users who self-host an instance are vulnerable. This problem was fixed in server-2024-09-25. Those who follow the tagged releases should update to server-2024-09-25 or later. Those who follow the rolling tag on DockerHub docker pull shieldsio/shields:next to update to the latest version. As a workaround blocking access to the endpoints /badge/dynamic/json /badge/dynamic/toml and /badge/dynamic/yaml (e.g: via a firewall or reverse proxy in front of your instance) would prevent the exploitable endpoints from being accessed.
