Name of the Vulnerable Software and Affected Versions OpenStack Swift versions 2.10.1 and earlier OpenStack Swift versions 2.11.0 through 2.13.0 OpenStack Swift version 2.14.0 OpenStack Swift versions prior to 2.15.2

Description The issue is related to the proxy-server logging full tempurl paths in OpenStack Swift, potentially leaking reusable tempurl signatures to anyone with read access to these logs. This could allow a remote attacker to access confidential data. All Swift deployments using the tempurl middleware are affected.

Recommendations For OpenStack Swift versions 2.10.1 and earlier, update to version 2.15.2 or later to resolve the issue. For OpenStack Swift versions 2.11.0 through 2.13.0, update to version 2.15.2 or later to resolve the issue. For OpenStack Swift version 2.14.0, update to version 2.15.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the proxy-server logs to minimize the risk of exploitation.
