According to the versions of the cups packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In     versions 2.4.16 and prior, in a network-exposed cupsd with a shared target queue, an unauthorized client     can send a Print-Job to that shared PostScript queue without authentication. The server accepts a page-     border value supplied as textWithoutLanguage, preserves an embedded newline through option escaping and     reparse, and then reparses the resulting second-line PPD: text as a trusted scheduler control record. A     follow-up raw print job can therefore make the server execute an attacker-chosen existing binary such as     /usr/bin/vim as lp. At time of publication, there are no publicly available patches.(CVE-2026-34980)

    OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In     versions 2.4.16 and prior, a local unprivileged user can coerce cupsd into authenticating to an attacker-     controlled localhost IPP service with a reusable Authorization: Local ... token. That token is enough to     drive /admin/ requests on localhost, and the attacker can combine CUPS-Create-Local-Printer with printer-     is-shared=true to persist a file:///... queue even though the normal FileDevice policy rejects such URIs.
    Printing to that queue gives an arbitrary root file overwrite; the PoC below uses that primitive to drop a     sudoers fragment and demonstrate root command execution. At time of publication, there are no publicly     available patches.(CVE-2026-34990)

Tenable has extracted the preceding description block directly from the EulerOS cups security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
