CVE-2026-50221 (GCVE-0-2026-50221)
Vulnerability from cvelistv5 – Published: 2026-06-23 17:03 – Updated: 2026-06-23 17:38
VLAI?
Summary
In OpenStack Swift before 2.37.2, proxy-server does not strip internal update headers (X-Container-Host, X-Container-Device, X-Delete-At-Host, X-Delete-At-Device) from client requests before forwarding them to object-servers. An authenticated user with write access can inject these headers to redirect container update requests to an attacker-controlled server, enabling server-side request forgery. The SSRF requests expose internal cluster metadata including storage policy indexes, partition mappings, device names, and when at rest encryption is enabled, cipher text and initialization vectors for the container-level encryption key. The attacker can also cause "ghost listings" in arbitrary containers via the shard-range redirect mechanism.

CVE-2026-49017 (GCVE-0-2026-49017)
Vulnerability from cvelistv5 – Published: 2026-05-27 01:57 – Updated: 2026-06-02 17:33
VLAI?
Summary
In OpenStack Swift before 2.36.2 and 2.37.2, s3api middleware enters an infinite loop when processing a truncated aws-chunked PUT request body. The StreamingInput class repeatedly appends an empty buffer and re-reads, causing the proxy-server worker handling the request to become permanently unresponsive with increasing CPU and memory consumption. An authenticated attacker can systematically exhaust all proxy-server workers, resulting in denial of service. The defect was introduced in Swift 2.36.0.
Severity ?
