Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Unsanitized attachment filenames containing path traversal sequences (such as backslashes or forward slashes) allowed remote attackers to write files to arbitrary locations on the local filesystem during downloads. Future attachment-handling features must aggressively sanitize file paths prior to invoking local file operations.
Denial of Service: The REST client was susceptible to denial of service because it trusted remote 'Retry-After' headers without validation, leading to potential hangs or crashes via excessive sleep durations. Strict clamping of delay values and upper bounds on retry attempts are critical to maintaining application availability.
