Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XXE: Insecure default XML parser configurations allowed attackers to execute XML External Entity (XXE) attacks via malicious job descriptions, exposing sensitive local files or internal services. Developers must consistently disable inline DOCTYPE declarations in all XML parsers.
Code Injection: Unchecked parameters passed to administrative or messaging jobs allow remote attackers to achieve arbitrary code execution. Developers should enforce strict validation on dynamic job arguments and restrict execution of administrative utility jobs.
