CVE-2026-49017 (opens in a new tab)How to fix?
A fix was pushed into the master branch but not yet published.
Overview
swift is an OpenStack Object Storage
Affected versions of this package are vulnerable to Infinite loop via the StreamingInput process. An attacker can cause proxy-server workers to become permanently unresponsive and exhaust system resources by sending specially crafted, truncated aws-chunked PUT requests to the s3api middleware.
Workaround
This vulnerability can be mitigated by disabling the s3api middleware in the Swift proxy server configuration if S3 API compatibility is not required.
