CVE-2026-40563: CWE-94 Improper Control of Generation of Code ('Code Injection') in Apache Software Foundation Apache Atlas
Description: Improper Control of Generation of Code ('Code Injection') vulnerability in Apache Atlas Apache Atlas exposes a DSL search endpoint that accepts user-supplied query strings. Attacker can alter Gremlin traversal logic within grammar-allowed characters to access unintended data Affect Version: This issue affects Apache Atlas: from 0.8 through 2.4.0. For the affect version >= 2.0, vulnerability is only when Atlas is deployed with below non-default configuration.atlas.dsl.executor.traversal=false Mitigation: Users are recommended to upgrade to version 2.5.0, which fixes the issue.
AI Analysis
Technical Summary
Apache Atlas exposes a DSL search endpoint that accepts user-supplied query strings. Due to improper control of code generation (CWE-94), an attacker can manipulate the Gremlin traversal logic within grammar-allowed characters to access data beyond intended scope. This affects versions 0.8 through 2.4.0, with a conditional vulnerability in versions 2.0 and above depending on configuration. The vulnerability has a CVSS 3.1 score of 8.1, indicating high severity with network attack vector, low attack complexity, requiring low privileges, no user interaction, and impacts confidentiality and integrity but not availability. The vendor recommends upgrading to version 2.5.0 to remediate the issue.
Potential Impact
Successful exploitation allows an attacker with low privileges to perform code injection via the DSL search endpoint, potentially accessing sensitive data beyond intended permissions. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade Apache Atlas to version 2.5.0, which addresses this vulnerability. For versions 2.0 and above, ensure that the configuration 'atlas.dsl.executor.traversal' is not set to false to avoid exposure. Patch status is not explicitly confirmed in the vendor advisory, but upgrading to 2.5.0 is the recommended fix.
