What happened

CISA's weekly bulletin recorded CVE-2026-76832, a path traversal flaw in the Agno agent framework's PythonTools rated CVSS 8.8, where prompt-injected content could escape the intended base directory to read, write, or execute files as the process user.

Why it matters

It is a clean example of prompt injection turning into filesystem access because the file tool trusted the path the model handed it.
