Patchwork is a patch-tracking system used in email-based development workflows. It records submitted code patches, links them to discussion threads, and shows their review state, such as new, under review, accepted, or rejected. In projects that rely on mailing lists, Patchwork helps turn scattered email traffic into an organized queue of changes.
From a security perspective, Patchwork matters because traceability is a defense. It creates a visible audit trail for who submitted a patch, who reviewed it, and whether concerns were raised before merge. That makes it harder for a malicious or careless change to slip through unnoticed, and it supports incident response when code history must be checked. Attackers may try to abuse trust in the review process by submitting deceptive patches or exploiting weak review discipline, so Patchwork is most effective when paired with careful human review, testing, and maintainer oversight.
