GHSA-m8f5-rh7h-vgg3: microsandbox (CVE-2026-61670)

Package	Ecosystem	Affected	Fixed in
microsandbox	crates.io	<0.5.10	0.5.10

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Microsandbox versions before 0.5.10 pass the full network configuration, including real secret values, and any per-sandbox environment values as command-line arguments to the sandbox child process. Any local user or co-resident process on the same host can read these secrets from the process listing (for example via /proc or ps) for as long as the sandbox runs. Upgrade to microsandbox 0.5.10, which fixes the issue.
