CVE-2026-71190

A flaw was found in OpenStack Swift's proxy server. The Accept header parser uses a regular expression that is vulnerable to catastrophic backtracking. An unauthenticated attacker can send a crafted Accept header with a small number of backslash characters in an unterminated quoted string, causin...

CVE-2026-71192

A flaw was found in the S3API middleware of OpenStack Swift. When configured with s3acl=true non-default, Swift-native control headers such as X-Copy-From and X-Copy-From-Account are not sanitized from S3 API requests. Because the S3 ACL mode bypasses Swift's native authorization, an authenticate...

CVE-2026-71191

A flaw was found in the S3API middleware of OpenStack Swift. The SigV4 presigned URL implementation does not require that semantic x-amz- headers be included in the request signature. An attacker who obtains a presigned PUT URL can inject unsigned headers such as X-Amz-Copy-Source to copy objects...

CVE-2026-71192

In OpenStack Swift through 2.38.0, the S3API middleware does not sanitize Swift-native control headers X-Copy-From, X-Copy-From-Account from S3 API requests when s3acl=true. An attacker can inject these headers into a signed PUT request targeting their own bucket, causing Swift to perform a...

CVE-2026-71191

In OpenStack Swift through 2.38.0, S3API middleware does not enforce that semantic x-amz- headers are covered by the SigV4 signature on presigned URL requests. An attacker who obtains a presigned PUT URL can inject an unsigned X-Amz-Copy-Source header, causing Swift to perform a server-side copy...

CVE-2026-71190

In OpenStack Swift through 2.38.0, the proxy server Accept header parser contains a regular expression vulnerable to catastrophic backtracking ReDoS. The "qdtext" pattern ?:^"|\. allows an unauthenticated remote attacker to send a crafted Accept header that causes exponential CPU consumption in...

CVE-2026-71192

CVE-2026-71192 affects OpenStack Swift up to version 2.38.0, where the S3API middleware does not sanitize Swift-native control headers (X-Copy-From, X-Copy-From-Account) in S3 API requests when the non-default configuration s3_acl=true is used. An attacker can inject these headers into a signed P...
