This functionality is intended for use in high-trust environments, and is disabled by default. However, in Druid 0.20.0 and earlier, it is possible for an authenticated user to send a specially-crafted request that forces Druid to run user-provided JavaScript code for that request, regardless of server configuration. This can be leveraged to execute code on the target machine with the privileges of the Druid server process.","published_at":"2021-01-29T19:15:12Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://lists.apache.org/thread.html/rfda8a3aa6ac06a80c5cbfdeae0fc85f88a5984e32ea05e6dda46f866%40%3Cdev.druid.apache.org%3E","http://www.openwall.com/lists/oss-security/2021/01/29/6","https://lists.apache.org/thread.html/r64431c2b97209f566b5dff92415e7afba0ed3bfab4695ebaa8a62e5d%40%3Cdev.druid.apache.org%3E","https://lists.apache.org/thread.html/rc167d5e57f3120578718a7a458ce3e73b3830ac4efbb1b085bd06b92%40%3Cdev.druid.apache.org%3E","https://lists.apache.org/thread.html/r20e0c3b10ae2c05a3aad40f1476713c45bdefc32c920b9986b941d8f%40%3Cannounce.apache.org%3E","https://lists.apache.org/thread.html/r4f84b542417ea46202867c0a8b3eaf3b4cfed30e09174a52122ba210%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/rea9436a4063927a567d698431ddae55e760c3f876c22ac5b9813685f%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/r121abe8014d381943b63c60615149d40bde9dc1c868bcee90d0d0848%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/rfeb775822cd3baef1595b60f6860f5ca849eb1903236483f3297bd5c%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/r04fa1ba93599487c95a8497044d37f8c02a439bfcf92b4567bfb7c8f%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/r87aa94e28dd21ee2252d30c63f01ab9cb5474ee5bdd98dd8d7d734aa%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/r7dff4790e7a5c697fc0360adf11f5aeb31cd6ad80644fffee690673c%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/ra4225912f501016bc5e0ac44e14b8d6779173a3a1dc7baacaabcc9ba%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/r5ef625076982aee7d23c23f07717e626b73f421fba5154d1e4de15e1%40%3Ccommits.druid.apache.org%3E","https://lists.apache.org/thread.html/r443e2916c612fbd119839c0fc0729327d6031913a75081adac5b43ad%40%3Cdev.druid.apache.org%3E","http://packetstormsecurity.com/files/162345/Apache-Druid-0.20.0-Remote-Command-Execution.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:15:16.213984Z"},"effective_severity":null,"badges":["poc","epss"],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-druid","product_name":"Apache Druid","version_start":"0.20.0 and earlier","version_start_inclusive":true,"version_end":"0.20.0","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-druid:0.20.0 and earlier:0.20.0"}],"exploit_refs":[{"source":"nuclei","kind":"nuclei","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2021/CVE-2021-25646.yaml","title":"Apache Druid -
