Expression injection via unrestricted JXPath functions
Published Apr 20, 2025 · Updated Aug 26, 2026
Expression injection in TwsCachedXPathAPI in Convertigo through 8.3.4 allows local users to invoke dangerous functions through crafted XPath. The selectList and selectNode methods create JXPathContext instances without replacing the default function library, so attacker-controlled expressions can resolve and invoke exposed Java methods. Exploitation requires influence over an evaluated XPath expression, low privileges, and user interaction; method invocation can alter application data, while command execution depends on reachable methods.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
