What is CVE-2026-40563?

Apache Atlas has a code injection vulnerability that stems from improper control over the generation of code via its DSL search endpoint. This endpoint mistakenly allows attackers to submit user-defined query strings, enabling them to manipulate Gremlin traversal logic. By utilizing allowed grammar characters, an attacker may gain access to unauthorized data, presenting a significant security risk. It is crucial for users of Apache Atlas, especially in versions ranging from 0.8 to 2.4.0 with specific configurations, to address this vulnerability by upgrading to version 2.5.0 to safeguard their data.

Affected Version(s)

Apache Atlas 0.8 <= 2.4.0
