Apache Druid includes the ability to execute user-provided JavaScript code embedded in various types of requests. 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.

Defenders still triage vulnerabilities one CVE at a time, while increasingly automated attackers combine them at machine speed. Omenwave models the plausible pathways by which this CVE could be chained with others — surfacing them for research and awareness, with evidence for each step.
The access level the source grants already meets or exceeds the access level the destination requires — the position carries over.
A sandbox bypass vulnerability exists in Jenkins Pipeline: Groovy Plugin 2.63 and earlier in pom.xml, src/main/java/org/jenkinsci/plugins/workflow/cp…
The source lands the attacker on the host (code execution or an established foothold), which satisfies the destination's requirement for local access.
Microsoft Exchange Server Elevation of Privilege Vulnerability
The access level the source grants already meets or exceeds the access level the destination requires — the position carries over.
Improper control of generation of code ('code injection') in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.
The access level the source grants already meets or exceeds the access level the destination requires — the position carries over.
Microsoft Exchange Server Elevation of Privilege Vulnerability
The access level the source grants already meets or exceeds the access level the destination requires — the position carries over.
A remote code execution vulnerability exists in Microsoft Exchange software when the software fails to properly handle objects in memory, aka 'Micros…
