{"apiVersion":"1.0","identifier":"CVE-2026-55758","description":"CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles, and more to the game. Prior to 1.120.0, the SSRF protection in projects/core/src/main/java/dan200/computercraft/core/apis/http/options/AddressPredicate.java blocks the RFC 6052 64:ff9b::/96 NAT64 prefix but omits the RFC 8215 64:ff9b:1::/48 local-use prefix. On a dual-stack server using RFC 8215 NAT64, an unauthenticated user who can execute Lua code can use http.request or http.websocket with an address under 64:ff9b:1::/48 to reach loopback, RFC 1918, cloud metadata, or internal API endpoints because PrivatePattern.matches() does not classify the mapped IPv6 address as private. This issue is fixed in version 1.120.0.","publishedAt":"2026-08-27T20:17:50","lastModifiedAt":"2026-08-27T20:17:50","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55758","cvssScore":6.9,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:L/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","epssProbability":0.00427,"riskScore":0.72,"affectedProduct":"CC: Tweaked","affectedVersions":"<1.120.0","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-55758","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-55758","en":"https://www.redsauce.net/en/cves/CVE-2026-55758","fr":"https://www.redsauce.net/fr/cves/CVE-2026-55758","pt":"https://www.redsauce.net/pt/cves/CVE-2026-55758","de":"https://www.redsauce.net/de/cves/CVE-2026-55758","sk":"https://www.redsauce.net/sk/cves/CVE-2026-55758","el":"https://www.redsauce.net/el/cves/CVE-2026-55758"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-55758"}}
