{"apiVersion":"1.0","identifier":"CVE-2026-41136","description":"free5GC AMF provides Access & Mobility Management Function (AMF) for free5GC, an an open-source project for 5th generation (5G) mobile core networks. Prior to version 1.4.3, the `HTTPUEContextTransfer` handler in `internal/sbi/api_communication.go` does not include a `default` case in the `Content-Type` switch statement. When a request arrives with an unsupported `Content-Type`, the deserialization step is silently skipped, `err` remains `nil`, and the processor is invoked with a completely uninitialized `UeContextTransferRequest` object. Version 1.4.3 contains a fix.","publishedAt":"2026-04-22T00:16:29","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41136","cvssScore":5.5,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/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","epssProbability":0.00282,"riskScore":0.56,"affectedProduct":"free5GC AMF","affectedVersions":"<1.4.3","vulnerabilityType":"Core software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41136","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41136","en":"https://www.redsauce.net/en/cves/CVE-2026-41136","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41136","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41136","de":"https://www.redsauce.net/de/cves/CVE-2026-41136","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41136","el":"https://www.redsauce.net/el/cves/CVE-2026-41136"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41136"}}
