CVE-2022-47950 : What You Need to Know
Discover the impact of CVE-2022-47950, a security flaw in OpenStack Swift enabling unauthorized read access to sensitive data. Learn about mitigation and preventive measures.
An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This impacts both s3api deployments (Rocky or later), and swift3 deployments (Queens and earlier, no longer actively developed).
