CVE-2026-86319 Details
Description
A vulnerability has been found in java-json-tools json-patch up to 1.13. Affected by this vulnerability is the function JsonPatch.apply of the file src/main/java/com/github/fge/jsonpatch/JsonPatch.java of the component Patch Operation Handler. The manipulation leads to resource consumption. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A denial-of-service vulnerability has been identified in java-json-tools json-patch versions prior to 1.13. The issue arises in the JsonPatch.apply function, where an unbounded number of patch operations can be processed. This lack of limitation allows for excessive resource consumption, as each operation requires a deep copy of the JSON document. The vulnerability can be exploited remotely, and has been disclosed publicly.
To address this vulnerability, it is recommended to implement a configurable maximum operation count for JSON Patch documents, add an operation timeout for long-running patches, and consider using structural sharing techniques to reduce memory consumption.
