Technical details

The vulnerability is an XML External Entity (XXE) injection affecting multiple server paths in MarkLogic 12.x (before 12.1.0) and 11.x (before 11.3.7), where XXE processing is enabled by default. An unauthenticated attacker with network access can craft malicious XML payloads to be processed by the server, leading to server-side request forgery (SSRF) or local file disclosure (LFI). The attack requires no user interaction beyond sending the crafted XML to an affected endpoint.

Affected products

Progress MarkLogic Server 11.x before 11.3.7, 12.x before 12.1.0
