Background

dogtag-pki is an enterprise software system designed for managing Public Key Infrastructure (PKI) deployments. It includes components such as Certificate Authority (CA), Key Recovery Authority (KRA), Online Certificate Status Protocol (OCSP) Manager, Token Key Service (TKS), Token Processing Service (TPS), Automatic Certificate Management Environment (ACME) Responder, and Enrollment over Secure Transport (EST) Responder. This system is crucial for organizations that require secure management of digital certificates and keys.

Vulnerability Detail

The vulnerability arises from security bypasses in the jackson-databind library, which is used by dogtag-pki. Specifically, CVE-2026-54512 and CVE-2026-54513 allow for arbitrary code execution through a PolymorphicTypeValidator bypass and a general security bypass, respectively. This could lead to unauthorized access and control over the affected systems, posing significant risks to data integrity and confidentiality.

Conclusion

The dogtag-pki package has a critical vulnerability that allows for arbitrary code execution due to security bypasses in the jackson-databind library. It is crucial to update to the patched version to protect your systems from potential exploitation. Utilize tools like Vulert to monitor your applications for vulnerabilities effectively.
