CVE-2026-34990

A flaw was found in OpenPrinting CUPS. A local unprivileged user can exploit this vulnerability by coercing the cupsd service to authenticate to an attacker-controlled Internet Printing Protocol IPP service. This allows the user to create a persistent printer queue that can overwrite arbitrary...

CVE-2026-27447

A flaw was found in OpenPrinting CUPS. This authorization bypass vulnerability allows an unprivileged user to gain unauthorized access to restricted operations. This can be exploited by using a username that differs only in case from an authorized user during authorization checks. Mitigation...
