{"id":"CVE-2026-47695","state":"PUBLISHED","title":"CC-Tweaked has an SSRF Protection Bypass with NAT64","description":"CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles, and more to the game. Prior to version 1.119.0, CC-Tweaked's HTTP API (`http.request`, `http.websocket`) blocks requests to private network ranges to prevent server-side request forgery (SSRF). This protection can be bypassed on IPv6-capable servers using NAT64 well-known prefix addresses (`64:ff9b::/96`). An attacker who can execute Lua code can reach any internal IPv4 service that the filter is intended to block, by addressing it as `http://[64:ff9b::<ipv4-as-hex>]/` instead of its direct IPv4 address. This affects any CC-Tweaked deployment on a network with NAT64 routing — a configuration that is standard on AWS, GCP, and other cloud platforms when using IPv6-only subnets. Version 1.119.0 fixes the issue.","publishedAt":"2026-07-21T20:51:07.866Z","updatedAt":"2026-07-23T14:05:43.090Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["cc-tweaked CC-Tweaked"],"affected":[{"vendor":"cc-tweaked","product":"CC-Tweaked","versions":[{"version":"< 1.119.0","status":"affected"}]}],"references":["https://github.com/cc-tweaked/CC-Tweaked/security/advisories/GHSA-5jh9-2h63-pw4q"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47695.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47695","state":"PUBLISHED","datePublished":"2026-07-21T20:51:07.866Z","dateUpdated":"2026-07-23T14:05:43.090Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-19T21:18:20.403Z"},"containers":{"cna":{"title":"CC-Tweaked has an SSRF Protection Bypass with NAT64","descriptions":[{"lang":"en","value":"CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles, and more to the game.
