services / Google Cloud / Pub/Sub snapshot

A Pub/Sub snapshot captures the state of a pub/sub subscription. It retains all unacknowledged messages in the source subscription at the time of creation, and any messages published after the snapshot was created.

pubsub.​snapshots.​seek

The seek functionality allows for replay/redelivery of the messages in the snapshot. This can allow an attacker to read Pub/Sub messages, which may be sensitive.

Risks

Scope: HIGH

This privilege may grant access to sensitive data from a single organizational function, or allow interruption of a service supporting a single organizational function.
