In versions 2.52.8 and below, when using Fiber's Ctx.BodyParser to parse form data containing a large numeric key that represents a slice index (e.g., test.18446744073704), the application crashes due to an out-of-bounds slice allocation in the underlying schema decoder. The root cause is that the decoder attempts to allocate a slice of length idx + 1 without validating whether the index is within a safe or reasonable range. If the idx is excessively large, this leads to an integer overflow or memory exhaustion, causing a panic or crash. This is fixed in version 2.52.9."}]}, "problemtype": {"problemtype_data": [{"description": []}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2025-54801", "ASSIGNER": "security-advisories@github.com"}}, "impact": {}, "publishedDate": "2025-08-06T00:15Z", "configurations": {"nodes": [], "CVE_data_version": "4.0"}, "lastModifiedDate": "2025-08-07T14:15Z"}
