Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Command Injection: Improperly escaped help texts generated for fish-completions can lead to command substitution or variable expansion when the shell loads the completion script. Developers must ensure that all generated completions adequately quote and escape dynamic string fields.

Memory Corruption: Unsound public API designs (such as arbitrary byte-index slicing of OsStr) can lead to invalid OsStr references and undefined behavior within unsafe blocks. Public interfaces handling OS strings must enforce strict validation before delegating to unsafe operations.

Privilege Escalation: Permissive default GITHUB_TOKEN permissions in GitHub Action workflows can allow compromised runs to obtain write access to the repository, escalating privileges. Workflows should enforce the principle of least privilege explicitly.
