OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the `AuthType` is set to anything but `Basic`, if the request contains an `Authorization: Basic ...` header, the password is not checked. This results in authentication bypass. Any configuration that allows an `AuthType` that is not `Basic` is affected. Version 2.4.13 fixes the issue.
Risk to organizations includes unauthorized access to sensitive resources, which may lead to data breaches or misuse of the printing capabilities. Given the critical role of printing in many environments, the potential impact is significant.
Organizations should prioritize patching immediately to mitigate this vulnerability. The lack of a patch could expose sensitive information and create a pathway for further attacks.
Currently, there are no known exploits for this vulnerability, but its exploitability score is high, indicating that it could be easily targeted by attackers without significant effort.
In summary, organizations using OpenPrinting CUPS versions 2.4.12 and earlier should take immediate action to upgrade to version 2.4.13 or later.
Vulnerability Details
The vulnerability identified as CVE-2025-58060 falls under the category of authentication bypass, specifically classified as CWE-287. The CVSS score for this vulnerability is 8, designating it as high severity. This score reflects the potential impact on confidentiality, integrity, and availability due to the authentication bypass that could be exploited under local attack vectors.
The vulnerability affects the OpenPrinting CUPS component, and specifically all versions prior to the vendor patch in version 2.4.13. The vulnerability was published on September 11, 2025.
Technical Analysis
The root cause of CVE-2025-58060 lies in the way OpenPrinting CUPS handles authentication types. When the `AuthType` is set to anything other than `Basic`, the system does not validate the credentials if a request includes an `Authorization: Basic ...` header. This flaw can allow unauthorized users to bypass security checks, potentially leading to unauthorized access to printing services and sensitive data.
The attack vector for this vulnerability is considered local, meaning an attacker needs to have some form of access to the system where CUPS is running. The attack complexity is rated as low, indicating that an attacker could exploit the vulnerability without significant technical skill. Additionally, this vulnerability requires no privileges and does not necessitate user interaction.
The impacts of this vulnerability are notable: there is a low impact on confidentiality, but high impacts on integrity and availability, which means that compromised systems may lead to unauthorized modifications and disruptions in printing services.
Risk & Impact Analysis
Organizations using OpenPrinting CUPS should evaluate the risks associated with this vulnerability. The real-world deployment risk is high, as many enterprises rely on printing services for critical operations. The potential for unauthorized access through authentication bypass can lead to significant security concerns, including data breaches and misuse of resources.
Given the CVSS score of 8, organizations should address this vulnerability in their priority patch cycle. The urgency is compounded by the lack of known exploits, which suggests that attackers may soon develop methods to exploit this vulnerability as awareness spreads.
The blast radius for this issue is potentially wide, impacting any system using vulnerable configurations of OpenPrinting CUPS. Organizations must act swiftly to mitigate risks.

Affected Versions
OpenPrinting CUPS versions 2.4.12 and earlier are affected by this vulnerability. It is recommended to upgrade to version 2.4.13 or later to mitigate the risks associated with this flaw.
Mitigation & Remediation
To remediate CVE-2025-58060, organizations should apply the vendor patch by updating OpenPrinting CUPS to version 2.4.13. If immediate patching is not feasible, consider implementing configuration hardening by disallowing any `AuthType` settings other than `Basic` to prevent unauthorized access.
Additionally, organizations should monitor logs for any unusual authentication attempts and ensure that network controls are in place to restrict access to printing services.
For further guidance on implementing effective security measures, organizations can refer to our penetration testing services, which can help identify and remediate vulnerabilities effectively.
Detection Guidance
To detect potential exploitation attempts related to this vulnerability, organizations should monitor logs for any incidents of failed authentication when using non-Basic `AuthType` settings. Additionally, reviewing access logs for unauthorized printing requests can help identify potential breaches.
Behavioral anomalies in user access patterns, such as repeated failed access attempts or unusual access times, should also be flagged for further investigation.
AppSecure Threat Intelligence Insight
The emergence of CVE-2025-58060 highlights ongoing security challenges in authentication mechanisms across software systems. Security teams should be vigilant in their monitoring and updating practices to avoid similar vulnerabilities.
To strengthen defenses, organizations should consider adopting a comprehensive security framework that includes regular security audits and updates. For further insights, refer to our vulnerability management program and our guidance on penetration testing methodology to proactively identify and mitigate security risks.
Lastly, adopting continuous security testing practices can help organizations stay ahead of emerging threats, ensuring their systems remain resilient against exploitation.
