Pardus-Parental-Control: Improper Access Control

Published Updated By the CyberSecBulletin desk

CVE-2026-9085 is a high-severity improper access control vulnerability in Pardus-Parental-Control from TUBITAK BILGEM Software Technologies Research Institute, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 0.7.0 as the first without the flaw, so updating Pardus-Parental-Control to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.14% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

Incorrect Permission Assignment for Critical Resource, Improper Access Control vulnerability in TUBITAK BILGEM Software Technologies Research Institute Pardus-Parental-Control allows DNS Spoofing. This issue affects Pardus-Parental-Control: from <=0.5.1 before 0.7.0.

The underlying weakness: Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
