    CVE ID         : CVE-2026-50221 CVE-2026-71190
    Debian Bug     : 1140678 1142973

    Multiple security vulnerabilities were discovered in Swift, a
    distributed virtual object store, which could result in information
    disclosure via SSRF or denial of service.

    For Debian 12 bookworm, these problems have been fixed in version
    2.30.1-0+deb12u2.

    We recommend that you upgrade your swift packages.

    For the detailed security status of swift please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/swift
