{"cve":"CVE-2022-51016","nvd":{"published":"2026-09-07T13:17:23.607","modified":"2026-10-08T16:16:46.753","status":"Deferred","description":"PocketMine-MP 3.x (before 3.27.0) does not implement Minecraft Bedrock protocol encryption, so the server cannot verify that a connecting client possesses the private key corresponding to its login token. An attacker who captures a valid login from another player's session (for example by tricking the player into connecting to an attacker-controlled server) can replay that login to impersonate the victim and pass XBOX Live authentication until the JWT token expires (typically 2-3 days). This affects servers directly reachable over the internet that are not behind a proxy with encryption enabled. Fixed in 4.0.0 and backported to 3.27.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-294"],"references":["https://github.com/pmmp/PocketMine-MP/commit/d28be4eaf24a890f7ef110a51181a3d806a6acca","https://github.com/pmmp/PocketMine-MP/security/advisories/GHSA-h79x-98r2-g6qc","https://www.vulncheck.com/advisories/pocketmine-mp-before-4.0.0-authentication-bypass-via-login-replay"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2022-51016","score":0.0024,"percentile":0.14954,"date":"2026-10-25"},"kev":null,"osv":[],"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).
