Summary

CVE-2025-49127 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability. Its CVSS base score is 8.9 (High).

Operationally, ranked in the top 17.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

Kafbat UI, a web-based interface for managing Apache Kafka clusters, is affected by an unsafe deserialization vulnerability (CWE-502) in version 1.0.0. The flaw stems from deserialization of untrusted data and carries a CVSS 4.0 score of 8.9, reflecting network-accessible attack conditions with no required authentication or user interaction.

An unauthenticated remote attacker can supply a malicious serialized payload to the application and achieve arbitrary code execution on the server, resulting in full compromise of confidentiality, integrity, and availability.

The issue is resolved in release 1.1.0, as documented in the corresponding GitHub security advisory GHSA-g3mf-c374-fgh2 and the project’s release notes; administrators should upgrade promptly to eliminate the exposure. The associated EPSS score has remained flat at 0.0171 with no material increase since disclosure.
