OpenViking versions prior to 0.3.3 contain a missing authorization vulnerability in the task polling endpoints that allows unauthorized attackers to enumerate or retrieve background task metadata created by other users. Attackers can access the /api/v1/tasks and /api/v1/tasks/{task_id} routes without authentication to expose task type, task status, resource identifiers, archive URIs, result payloads, and error information, potentially causing cross-tenant interference in multi-tenant deployments.

OpenViking versions 0.2.5 prior to 0.2.14 contain a missing authentication vulnerability in the bot proxy router that allows remote unauthenticated attackers to access protected bot proxy functionality by sending requests to the POST /bot/v1/chat and POST /bot/v1/chat/stream endpoints. Attackers can bypass authentication checks and interact directly with the upstream bot backend through the OpenViking proxy without providing valid credentials.

OpenViking versions 0.2.1 and prior, fixed in commit 46b3e76, contain a path traversal vulnerability in the .ovpack import handling that allows attackers to write files outside the intended import directory. Attackers can craft malicious ZIP archives with traversal sequences, absolute paths, or drive prefixes in member names to overwrite or create arbitrary files with the importing process privileges.
