  "title": "Unauthenticated local file read in Kroki TikZ rendering",
  "summary": "Kroki versions before 0.31.2 can allow unauthenticated users to read files available to the container account through the TikZ diagram-rendering interface, even when safe mode is enabled. An attacker must be able to submit TikZ or LaTeX diagram content to a reachable Kroki API endpoint; returned diagram output may expose readable secrets or configuration data.",
  "mitigation": "Upgrade Kroki to version 0.31.2 or later. Until upgraded, restrict untrusted access to TikZ rendering endpoints and limit files and secrets available to the Kroki container.",
