Starting in version 2.52.6 and prior to version 2.52.7, `fiber.Ctx.BodyParser` can map flat data to nested slices using `key[idx]value` syntax, but when idx is negative, it causes a panic instead of returning an error stating it cannot process the data. Since this data is user-provided, this could lead to denial of service for anyone relying on this `fiber.Ctx.BodyParser`  functionality. Version 2.52.7 fixes the issue.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gofiber/fiber","events":[{"introduced":"e04f815c43cb8a84f4de90e1d1bd9507bc33fa8c"},{"fixed":"e115c08b8f059a4a031b492aa9eef0712411853d"}],"database_specific":{"cpe":"cpe:2.3:a:gofiber:fiber:*:*:*:*:*:go:*:*","extracted_events":[{"introduced":"2.52.6"},{"fixed":"2.52.7"},{"introduced":"2.0.0"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"versions":["v2.52.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-48075.json"}}],"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48075.json"},{"type":"ADVISORY","url":"https://github.com/gofiber/fiber/security/advisories/GHSA-hg3g-gphw-5hhm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48075"},{"type":"FIX","url":"https://github.com/gofiber/fiber/commit/e115c08b8f059a4a031b492aa9eef0712411853d"}],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-129"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48075.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P"}]}
