CVE-2026-81690 verify-usb before 1.4.9 Symlink Directory Traversal Code Execution

openssl-encrypt pip package before 1.4.9 contains a symlink-following flaw in its verify-usb v2 added-file allowlist scan. The scan enumerated the drive with rglob, which in CPython does not descend into symlinked directories and treats the symlink as an ordinary directory, while ONOFOLLOW on the...

CVE-2026-81097 rails-mcp-server 1.4.0 through 1.6.0 OS Command Execution via execute_ruby PTY Escape

The executeruby tool is documented as a read-only Ruby sandbox and is enforced by a pattern denylist together with replacements for the process-spawning methods on Kernel. The pseudo-terminal library's spawn entry points are neither in the denylist nor replaced, so a normal tool call could reach...
