CVE-2014-3120

HighCVSS 8.1/10Known exploited (CISA KEV)Last modified Jun 17, 2026

Description

The default configuration in Elasticsearch before 1.2 enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search. NOTE: this only violates the vendor's intended security policy if the user does not run Elasticsearch in its own independent virtual machine.
