Provider invocation via attacker-controlled URI scheme

Published Sep 1, 2026 · Updated Sep 1, 2026

Path deserialization in FasterXML jackson-databind allows remote attackers to invoke registered providers through untrusted JSON. JDKFromStringDeserializer.NioPathHelper.deserialize passes an attacker-selected URI scheme through Path.of and then calls getPath on the matching ServiceLoader FileSystemProvider without an allowlist. The built-in JDK providers are inert; resource access or network I/O requires an application to bind Path values and load a side-effecting third-party provider.
