AnyIO process-pool workers can block indefinitely on undrained stderr
Impact AnyIO starts process-pool workers with stderr connected to a pipe but never drains that pipe. The worker redirects stdin and stdout to /dev/null to protect its protocol, but does not redirect stderr even though the documentation says all three standard streams are redirected. Worker code...
CVE-2026-63349
AnyIO is a high level asynchronous concurrency and networking framework that works on top of either Trio or asyncio. In 4.14.0, AnyIO accepts the POSIX extragroups argument in anyio.runprocess and anyio.openprocess, but openprocess forwards the group argument to the backend instead of extragroups...

CVE-2026-63349
AnyIO 4.14.0, a high-level asynchronous concurrency framework for Python, contains a correctness bug in its POSIX subprocess helpers. When open_process() receives a non-None extra_groups argument, it incorrectly assigns the group variable instead of extra_groups to the backend's kwargs. As a resu...

GHSA-9GM9-C8MQ-VQ7M PraisonAI: OS Command Injection in MCPHandler.parse_mcp_command()
Summary The --mcp CLI argument is passed directly to shlex.split and forwarded through the call chain to anyio.openprocess with no validation, allowlist check, or sanitization at any hop, allowing arbitrary OS command execution as the process user. Details cli/features/mcp.py:61 source -...
