1) Improper Neutralization of Special Elements in Output Used by a Downstream Component (CVE-ID: CVE-2026-55453)

CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper neutralization of special elements in output used by a downstream component in the CUPS ipp backend status reporting path and scheduler PPD update handling when processing text printer-status attributes from a remote IPP printer. A remote attacker can return a crafted printer-status attribute containing injected newline characters and a forged PPD status line to execute arbitrary code.

Successful exploitation requires a CUPS queue that points to an attacker-controlled or compromised IPP printer, a Foomatic-backed PPD or filter profile that invokes foomatic-rip, and a later print job that uses the modified PPD. The demonstrated code execution occurs as user lp.
