Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Unchecked weak reference counter increments in custom reference-counted pointers can lead to overflow, potentially resulting in premature deallocation and use-after-free conditions. This undermines the core memory-safety guarantees of the atomic utility library.
Privilege Escalation: Over-privileged GitHub Actions workflows can be exploited during pull requests or automation tasks to manipulate repository resources. Implementing top-level, read-all or minimal permissions limits the blast radius of compromised runs.
