It has been classified as critical. Affected by this issue is some unknown functionality of the file /usr/bin/vim. This manipulation of the argument page-border causes input validation. This vulnerability appears as CVE-2026-34980. The attacker needs to be present on the local network. There is no available exploit. Detailsinfo A vulnerability classified as critical was found in OpenPrinting CUPS up to 2.4.16 on Linux. Affected by this vulnerability is an unknown code block of the file /usr/bin/vim. The manipulation of the argument page-border with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is: 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. The advisory is shared at github.com. This vulnerability is known as CVE-2026-34980 since 03/31/2026. The exploitation appears to be easy. Access to the local network is required for this attack. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/04/2026). There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2026-18887).
