A deeply nested JSON document, around 20 KB of nested arrays with the default thread stack, makes the JSONArray and JSONObject constructors throw a raw java.lang.StackOverflowError instead of a JSONException. Any application that parses untrusted JSON with this library can be made to fail the thread doing the parsing. The artifact is a 2013 repackage of third-party org.json classes, published once and never maintained, and no fixed version will be released.\n\n\nUsers of the affected version should apply the following mitigation.\n\nProduct version\ncom.vaadin.external.google:android-json 0.0.20131108.vaadin1\n\nMitigation\nNo fixed version will be released. Replace the artifact with an org.json implementation that limits the nesting depth, such as org.json:json 20231013 or later.\n\nArtifacts\nMaven coordinates / Vulnerable versions / Fixed version\ncom.vaadin.external.google:android-json / 0.0.20131108.vaadin1 / none\n\n## Affected\n\n- `com.vaadin.external.google:android-json <= 0.0.20131108.vaadin1`\n\n## Remediation\n\nNo fixed version will be released.
