CVE-2026-34980 describes an unauthenticated remote code execution vulnerability in OpenPrinting CUPS versions 2.4.16 and prior, affecting network-exposed cupsd instances with shared target queues. An attacker on the adjacent network can exploit this medium-severity flaw (CVSS 6.1) by sending a crafted Print-Job, which manipulates the 'page-border' value to execute an existing binary as the 'lp' user, leading to high confidentiality impact. Despite the low attack complexity, there is no public exploit code, active exploitation has not been observed, and community discussion is minimal, with no patches publicly available.
