Bugsink path traversal via event_id in ingestion

發布日:2025/7/29修改日:2025/7/30

描述

## Summary In affected versions, ingestion paths construct file locations directly from untrusted `event_id` input without validation. A specially crafted `event_id` can result in paths outside the intended directory, potentially allowing file overwrite or creation in arbitrary locations. Submitting such input requires access to a valid DSN. While that limits exposure, DSNs are sometimes discoverable—for example, when included in frontend code—and should not be treated as a strong security boundary. ## Impact A valid DSN holder can craft an `event_id` that causes the ingestion process to write files outside its designated directory. This allows overwriting files accessible to the user running Bugsink. If Bugsink runs in a container, the effect is confined to the container’s filesystem. In non-containerized setups, the overwrite may affect other parts of the system accessible to that user. ## Mitigation Update to version `1.7.4`, `1.6.4`, `1.5.5` or `1.4.3` , which require `event_id` to be a valid UUID and normalizes it before use in file paths.
