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."},{"lang":"es","value":"Fiber es un framework web inspirado en Express y escrito en Go. En las versiones 2.52.8 y anteriores, al usar Ctx.BodyParser de Fiber para analizar datos de formulario que contienen una clave numérica grande que representa el índice de un segmento (p. ej., test.18446744073704), la aplicación se bloquea debido a una asignación de segmento fuera de los límites en el decodificador de esquema subyacente. La causa principal es que el decodificador intenta asignar un segmento con una longitud de idx + 1 sin validar si el índice se encuentra dentro de un rango seguro o razonable. Si el idx es excesivamente grande, se produce un desbordamiento de enteros o un agotamiento de memoria, lo que provoca un pánico o un bloqueo. Esto se solucionó en la versión 2.52.9."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"gofiber","product":"fiber","versions":[{"version":"< 2.52.9","status":"affected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"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:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","baseScore":8.7,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2025-08-07T13:59:43.620645Z","id":"CVE-2025-54801","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-789"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:gofiber:fiber:*:*:*:*:*:go:*:*","versionEndExcluding":"2.52.9","matchCriteriaId":"ABCB03A5-E695-43F0-B7B3-FC7C3D9B584F"}]}]}],"references":[{"url":"https://github.com/gofiber/fiber/commit/e115c08b8f059a4a031b492aa9eef0712411853d","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/gofiber/fiber/security/advisories/GHSA-qx2q-88mx-vhg7","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/gofiber/fiber/security/advisories/GHSA-qx2q-88mx-vhg7","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Vendor Advisory"]}]}}]}
