FKIE_CVE-2026-62676

Vulnerability from fkie_nvd - Published: 2026-08-21 18:16 - Updated: 2026-10-14 21:10
Severity
7.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N
Summary
Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. Prior to 0.3.0, the shared shell-command parser in omnigent/policies/builtins/_shell.py fails to recognize combined interpreter flags, the timeout, nice, setsid, and stdbuf wrappers, command substitutions, and a single background control operator. A gated git push or gh write hidden with these forms produces no parsed operation, causing the github.py write_repos and write_branches allowlist and the working_dir.py workspace confinement policies to abstain and allow the command. An authenticated or prompt-injected agent can therefore push to an unauthorized repository or branch or escape the intended workspace. This issue is fixed in version 0.3.0.

Un git push o gh write restringido oculto con estas formas no produce ninguna operaci\u00f3n analizada, lo que hace que la lista de permitidos write_repos y write_branches de github.py y las pol\u00edticas de confinamiento del espacio de trabajo de working_dir.py se abstengan y permitan el comando. Un agente autenticado o inyectado por prompt puede, por lo tanto, hacer push a un repositorio o rama no autorizados o escapar del espacio de trabajo previsto. Este problema se ha corregido en la versi\u00f3n 0.3.0."
