+  "details": "### Impact\nActive Support number helpers accept strings containing scientific notation (e.g. `1e10000`), which when converted to a string could be expanded into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability.\n\n### Releases\nThe fixed releases are available at the normal locations.",
