Description

SpiceDB is an open source database system for creating and managing security-critical application permissions. In versions 1.49.0 through 1.51.0, when SpiceDB starts with log level info, the startup "configuration" log will include the full datastore DSN, including the plaintext password, inside DatastoreConfig.URI. This issue has been fixed in version 1.51.1. If users are unable to immediately upgrade, they can work around this issue by changing the log level to warn or error.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs administrative privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity none, availability none.
