{"cve":"CVE-2026-47695","nvd":{"published":"2026-07-21T21:16:51.210","modified":"2026-07-23T18:28:20.910","status":"Deferred","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.","cvss_v4":{"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","score":7.1},"cvss_v3":null,"cwes":["CWE-918"],"references":["https://github.com/cc-tweaked/CC-Tweaked/security/advisories/GHSA-5jh9-2h63-pw4q","https://github.com/cc-tweaked/CC-Tweaked/security/advisories/GHSA-5jh9-2h63-pw4q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:53.305392138+00:00"},"epss":{"cve":"CVE-2026-47695","score":0.00468,"percentile":0.40539,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5jh9-2h63-pw4q","url":"https://osv.dev/vulnerability/GHSA-5jh9-2h63-pw4q","summary":"CC-Tweaked has an SSRF Protection Bypass with NAT64","modified":"2026-05-29T20:41:27.035563Z","packages":[{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.21-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.21-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.20.1-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.20.1-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.20.4-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.20.4-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.20.5-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.20.5-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.20.6-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.20.6-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.19.3-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.19.3-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.19.4-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.19.4-core","ranges":["<1.119.0"],"fixed":["1.119.0"]},{"ecosystem":"Maven","name":"cc.tweaked:cc-tweaked-1.20-core","purl":"pkg:maven/cc.tweaked/cc-tweaked-1.20-core","ranges":["<1.119.0"],"fixed":["1.119.0"]}]}],"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).
