Datasette 1.0a39 and 0.65.4 security releases

  • Datasette 1.0a39 and 0.65.4 security releases Today we're releasing two new security patch versions of Datasette: 1.0a39 and 0.65.4 - one for the current alpha series and one for the stable 0.65.x family.
  • These are security fixes which you should apply if you are running a Datasette instance on the public web - in particular if that instance mixes both public and private tables.
  • Following issues reported by Sevban Dönmez, Alex Garcia and I ran an extensive audit of Datasette using Claude Fable 5.1, GPT-5.6, and GPT-6 Astra.

Prompt-injection disclosure: a tool-enabled assistant leaked data via the lethal trifecta

  • An assistant with access to private data also ingested attacker-controlled web content.
  • A link-rendering tool became the exfiltration channel — all three trifecta legs present.
  • The fix was to break one leg: strip the outbound channel for untrusted-derived content.

Why it matters. The lethal trifecta (private data + untrusted content + exfiltration) is the canonical injection failure. Treat the model as untrusted and enforce permissions in your code, not the prompt.

Quick check: What is the most reliable mitigation for the lethal trifecta?
  1. Correct: Break at least one leg (e.g., remove the exfiltration channel for untrusted-derived actions)
  2. Add a stronger system prompt telling the model to refuse
  3. Increase the model size
  4. Lower the temperature to 0

Injection defenses in the prompt are bypassable. Remove one leg of data + untrusted content + exfiltration architecturally.
