Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: GraphQL endpoint was exempted from CSRF and CSP, allowing cross-site requests to mutate data; removal of exemptions restores framework defenses.
Auth Bypass: Overly broad Mozillians group allowlist granted localization rights to unintended members; narrowing to 'localization' enforces least privilege.
Path Traversal: Using untrusted project.name in filesystem paths allowed traversal; switching to slug removes path separators and dot-dot sequences.
