Exploitation Summary

EIP tracks 1 public exploit for CVE-2025-52999. PoCs published by sassoftware.

AI-analyzed exploit summary The repository appears to be a fork or clone of the Jackson library with no exploit-specific code or technical details related to CVE-2025-52999. It contains standard project files, CI workflows, and Java source files but lacks any PoC or analysis of the vulnerability.

Description

jackson-core contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. In versions prior to 2.15.0, if a user parses an input file and it has deeply nested data, Jackson could end up throwing a StackoverflowError if the depth is particularly large. jackson-core 2.15.0 contains a configurable limit for how deep Jackson will traverse in an input document, defaulting to an allowable depth of 1000. jackson-core will throw a StreamConstraintsException if the limit is reached. jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs. As a workaround, users should avoid parsing input files from untrusted sources.
