This result message could contain secrets that were not meant to be sent to remote sites, e.g. passwords/secrets. These secrets were not processed by the remote site but a rough site would have been able to retrieve these. This issue was found during internal review. *Affected Versions*: * 2.3.0 * 2.2.0 * 2.1.0 * 2.0.0 (EOL) *Vulnerability Management*: We have rated the issue with a CVSS Score of 5.3 Medium (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N`) and assigned `CVE-2024-6747`.
