AI-Jail: update de segurança, Docker vira opt-in

A security vulnerability in the AI-Jail sandbox, reported via issue #88 by @mdindoffer, allowed a sandbox escape through a Docker socket passthrough that granted effective host root access. The fix is available in version 1.16.0, which makes Docker socket mounting opt-in rather than automatic. Users are advised to update immediately.

Hoje de manhã abriram um issue importante no repositório do ai-jail: o issue #88, reportado pelo @mdindoffer, com o título “Sandbox escape via a docker socket passthrough (effective host root)”.

O report procedia, e a correção já está disponível na v1.16.0.

Se você usa o ai-jail, o update é o de sempre:

yay -Syu ai-jail-bin

brew update && brew upgrade ai-jail

cargo install ai-jail --force

mise cache clear && mise upgrade github:akitaonrails/ai-jail

Até a v1.15.x, o ai-jail montava o socket do Docker dentro da jaula automaticamente, sempre que /var/run/docker.sock

existia no host. Read-write. Sem aviso, sem flag, sem pedir opinião. Eu documentei isso no README como “favorece usabilidade”, e era verdade: agente de coding frequentemente precisa rodar um docker compose

pra subir banco de testes, e o passthrough automático poupava configuração.
