Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: The application retrieves workflow configuration files and processes object store paths dynamically. Path traversal sequences in configuration identifiers can allow unauthorized reading of local/remote storage paths if not validated at the route level.
Insecure Deserialization: The historical usage of the unmaintained 'sqlitedict' library exposed the application to arbitrary code execution vector CVE-2024-35515. The introduced SpillableDict utility must remain the standard to prevent insecure deserialization.
SQL Injection: User-supplied filters and regular expression fields merged directly into SQL query templates can lead to arbitrary SQL injection. Validation patterns must strictly reject quotes and SQL-meaningful sequences before string substitution.
