AnalysisAIv1 – Mar 12, 2026

Karapace versions before 6.0.0 contain a path traversal vulnerability in the backup restoration functionality that allows attackers to read arbitrary files from the system by crafting malicious backup files. Organizations using Karapace's backup/restore feature with untrusted backup sources are at risk, with the actual impact limited by the file permissions of the Karapace process. No patch is currently available, requiring users to restrict backup sources or disable the backup functionality until version 6.0.0 is released.

DescriptionGitHub Advisory

Karapace is an open-source implementation of Kafka REST and Schema Registry. Prior to version 6.0.0, there is a Path Traversal vulnerability in the backup reader (backup/backends/v3/backend.py). If a malicious backup file is provided to Karapace, an attacker may exploit insufficient path validation to perform arbitrary file read on the system where Karapace is running. The issue affects deployments that use the backup/restore functionality and process backups from untrusted sources. The impact depends on the file system permissions of the Karapace process. This issue has been patched in version 6.0.0.

Executive ViewAI

Why It Matters

Organizations using Karapace should be aware of moderate risk from CVE-2026-29190, a path traversal vulnerability rated CVSS 4.1. This could allow unauthorized file access. Organizations should apply vendor updates when available and monitor for exploitation.

Business Impact: Low

Compensating Controls

Apply vendor patch. If patching is delayed: restrict file access via WAF, implement allowlists.
