PYSEC-2026-4024 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-2026-64847

A flaw was found in AnyIO. Untrusted or faulty worker code can write a large amount of data to the standard error stderr stream. This data fills a pipe that the parent process fails to drain, causing the process-pool call to block indefinitely. This can lead to a Denial of Service DoS condition,...
