CVE-2026-14460: Missing Authorization in pardus-software Leads to Argument Injection

Technical summary

CVE-2026-14460 is a Missing Authorization (CWE-862) vulnerability in TUBITAK BILGEM's pardus-software affecting versions 1.0.4 and earlier. The flaw permits argument injection through insufficient authorization controls, allowing a local unprivileged user to manipulate application inputs without proper permission validation. The CVSS 3.1 vector (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) reflects local attack surface, low complexity exploitation, low privilege requirement, and cross-boundary impact across confidentiality, integrity, and availability.

Business impact

This vulnerability poses a significant risk to system administrators and organizations deploying pardus-software in multi-tenant or shared-access environments. An attacker with local access—whether a malicious employee, contractor, or compromised service account—can escalate privileges or manipulate application behavior without proper authorization checks. Potential impacts include unauthorized data access, system configuration tampering, and service disruption, all achievable without requiring additional user action or elevated starting privileges.

Affected systems

TUBITAK BILGEM pardus-software versions 1.0.4 and earlier are affected. Version 1.0.5 and later address this issue. Organizations should audit deployed instances to identify running versions within the vulnerable range, particularly in Linux distribution environments where pardus-software is commonly deployed.

Exploitability

Exploitation requires local system access and valid user credentials but no elevated privileges. The attack vector is local, complexity is low, and no user interaction is required once the attacker is authenticated. This makes it a practical concern for insider threats and for systems where multiple local accounts exist. No public exploit code has been indexed in the KEV catalog, indicating active exploitation is not yet widespread, but the technical barrier to exploitation is minimal.

Remediation

Organizations should upgrade pardus-software to version 1.0.5 or later. This patch version incorporates proper authorization checks to prevent argument injection by unprivileged users. Before patching, assess which systems run vulnerable versions and prioritize patching multi-user systems and shared infrastructure where local attack surface is highest.

Patch guidance

Apply upgrades to version 1.0.5 or later as released by TUBITAK BILGEM. Verify patch compatibility with your deployment environment and test in a staging environment before production rollout. If immediate patching is not possible, implement access controls to restrict local user accounts and monitor for suspicious argument injection attempts in application logs.

Detection guidance

Monitor system logs and application logs for unexpected argument patterns or elevated privilege attempts originating from unprivileged user accounts. Search for audit trails showing calls to pardus-software from users with insufficient authorization. Network-based detection is limited due to the local attack vector; endpoint detection and logging are essential. Correlate process execution logs with user privilege levels to identify potential exploitation chains.

Why prioritize this

This vulnerability merits urgent priority because it combines ease of exploitation (low complexity, no user interaction) with severe impact (HIGH severity, CVSS 8.8). Although it requires local access, the low privilege requirement makes it exploitable by any authenticated user, broadening the attack surface in any multi-user system. The absence from the KEV catalog suggests it may not yet be actively exploited at scale, creating a window for preemptive patching.

Risk score, explained

The CVSS 3.1 score of 8.8 reflects the confluence of low-barrier local exploitation (AV:L, AC:L, PR:L), lack of user interaction requirement (UI:N), and severe impact across all CIA triad dimensions (C:H, I:H, A:H). The cross-boundary scope (S:C) indicates the vulnerability can affect resources beyond the vulnerable component itself. While not CRITICAL (9.0+), the score appropriately captures HIGH risk due to the realistic exploitation scenario and broad impact potential.
