A single ~14-byte frame therefore commits as much memory as it cares to declare -- measured at 513 MiB against the Node.js server and 2 GiB against the D transport -- and in the Node.js case the connection is left open afterwards, so the frame can simply be sent again.\n\n\n\n\nThis issue affects Apache Thrift before 0.25.0.\n\n\n\nUsers are recommended to upgrade to version 0.25.0, which fixes the issue.","published":"2026-10-02T13:17:59.000Z","lastModified":"2026-10-02T18:17:06.000Z","status":"Deferred","sourceIdentifier":"security@apache.org","cvss":{"version":"4.0","score":8.7,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-130","CWE-789"],"affected":[],"epss":{"score":0.00342,"percentile":0.27503,"date":"2026-10-26","history":[{"date":"2026-10-03","score":0.00426,"percentile":0.34627}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.34%).
