A vulnerability classified as problematic was found in fluxcd source-controller up to 1.2.4. This vulnerability affects an unknown part of the component API. The manipulation with an unknown input leads to a log file vulnerability. The CWE definition for the vulnerability is CWE-532. Information written to log files can be of a sensitive nature and give valuable guidance to an attacker or expose sensitive user information. As an impact it is known to affect confidentiality. CVE summarizes:

The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, OCI, Helm repositories and S3-compatible buckets. The source-controller implements the source.toolkit.fluxcd.io API and is a core component of the GitOps toolkit. Prior to version 1.2.5, when source-controller was configured to use an Azure SAS token when connecting to Azure Blob Storage, the token was logged along with the Azure URL when the controller encountered a connection error. An attacker with access to the source-controller logs could use the token to gain access to the Azure Blob Storage until the token expires. This vulnerability was fixed in source-controller v1.2.5. There is no workaround for this vulnerability except for using a different auth mechanism such as Azure Workload Identity.

The advisory is shared for download at github.com. This vulnerability was named CVE-2024-31216 since 03/29/2024. The exploitation appears to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.
