# Gameyfin: missing authorization lets anonymous users read library data

Link for people: https://infrastack.ai/live/CVE-2026-129131 (this .md is for agents)

Gameyfin, a self-hosted game library manager, has a missing authorization check on Hilla endpoints marked AnonymousAllowed. An unauthenticated attacker can bypass login-required mode and read game catalog metadata, libraries, platforms, plugins and game requests.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Gameyfin affected range not listed fixed no fixed version listed

## How to check

- Check the Gameyfin version: anything below `2.6.2` is affected.
- Confirm whether login-required mode is enabled; the bypass only matters when it is.

## Fix

- Gameyfin: upgrade to `2.6.2` or later.

- [fix] Release notes: github.com https://github.com/gameyfin/gameyfin/releases/tag/v2.6.2

## From the sources

Gameyfin before 2.6.2 contains a missing authorization vulnerability that allows unauthenticated attackers to bypass login-required mode by calling Hilla endpoints annotated with @AnonymousAllowed. Attackers can POST to synchronous endpoint methods such as GameEndpoint.sync, which LiveSubscriptionSecurity never checks, to retrieve game catalog metadata, libraries, platforms, plugins and game requests.
