CVE-2025-61915: Openprinting Cups

Medium severity, CVSS 6.7. EPSS: 0.5% chance of exploitation in the next 30 days.

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.15, a user in the lpadmin group can use the cups web ui to change the config and insert a malicious line. Then the cupsd process which runs as root will parse the new config and cause an out-of-bound write. This issue has been patched in version 2.4.15.

Affected products

• Openprinting Cups: before 2.4.15 (fixed in 2.4.15)
