{"cve":"CVE-2025-48075","nvd":{"published":"2025-05-22T18:15:43.310","modified":"2026-06-17T09:29:06.793","status":"Analyzed","description":"Fiber is an Express-inspired web framework written in Go. 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.","cvss_v4":{"vector":"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","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-129"],"references":["https://github.com/gofiber/fiber/commit/e115c08b8f059a4a031b492aa9eef0712411853d","https://github.com/gofiber/fiber/security/advisories/GHSA-hg3g-gphw-5hhm","https://github.com/gofiber/fiber/security/advisories/GHSA-hg3g-gphw-5hhm"],"products":["gofiber:fiber"],"source":"nvd","synced_at":"2026-10-19T22:01:57.636215869+00:00"},"epss":{"cve":"CVE-2025-48075","score":0.00528,"percentile":0.44712,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hg3g-gphw-5hhm","url":"https://osv.dev/vulnerability/GHSA-hg3g-gphw-5hhm","summary":"Fiber panics when fiber.Ctx.BodyParser parses invalid range index","modified":"2026-09-10T03:50:57.551512938Z","packages":[{"ecosystem":"Go","name":"github.com/gofiber/fiber/v2","purl":"pkg:golang/github.com/gofiber/fiber/v2","ranges":[">=2.52.6 <2.52.7"],"fixed":["2.52.7"]}]},{"id":"GO-2025-3706","url":"https://osv.dev/vulnerability/GO-2025-3706","summary":"Fiber panics when fiber.Ctx.BodyParser parses invalid range index in github.com/gofiber/fiber","modified":"2026-02-04T02:29:43.147229Z","packages":[{"ecosystem":"Go","name":"github.com/gofiber/fiber","purl":"pkg:golang/github.com/gofiber/fiber","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gofiber/fiber/v2","purl":"pkg:golang/github.com/gofiber/fiber/v2","ranges":[">=2.52.6 <2.52.7"],"fixed":["2.52.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
