    Package        : cpp-httplib
    CVE ID         : CVE-2025-46728 CVE-2025-53629

    Multiple security issues were discovered in cpp-httplib, a C++ cross
    platform HTTP/HTTPS library, which could result in denial of service.

    For the stable distribution (trixie), these problems have been fixed in
    version 0.18.7-1+deb13u1.

    We recommend that you upgrade your cpp-httplib packages.
