Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Inadequate parsing of numeric user and group IDs can result in unexpected string fallback matches, potentially granting unexpected privileges during execution context setup. Developers must ensure numeric values are strictly validated via designated numeric parsers before fallback resolution.
Command Injection: Direct interpolation of workflow matrix variables into shell scripts within GitHub Actions allows malicious inputs to execute arbitrary commands. Untrusted runner parameters must always be bound to environment variables instead of injected directly into step runner blocks.
Privilege Escalation: The Docker CLI on Windows searches for plugin binaries in non-existent paths, enabling low-privileged local attackers to place malicious executables in those directories and achieve local privilege escalation. Security reviews must ensure that search paths for binaries are tightly scoped, validated, and non-writable by unprivileged users.
