Sensitive information exposure vulnerability in the Llama Stack server when PGVector is configured as the vector store provider. The issue is caused by insecure logging of configuration parameters in the PGVector initialization routine, where the database password is written to server logs without redaction. When a LlamaStackDistribution is created, the plaintext password is printed at INFO log level. An attacker or unauthorized user with access to pod or application logs can obtain valid database credentials, potentially leading to unauthorized database access. This flaw does not require user interaction and can compromise the confidentiality of backend services relying on PGVector.
