As a consequence the builds of such stacks are vulnerable to MITM attacks that allow the replacement of the original binaries with arbitrary ones. The stacks involved are Java 8 (alpine and centos), Android and PHP. The vulnerability is not exploitable at runtime but only when building Che.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-924"],"references":["https://bugs.eclipse.org/bugs/show_bug.cgi?id=540989","https://bugs.eclipse.org/bugs/show_bug.cgi?id=540989"],"products":["eclipse:che"],"source":"nvd","synced_at":"2026-10-19T21:23:41.316049955+00:00"},"epss":{"cve":"CVE-2021-41034","score":0.00407,"percentile":0.34942,"date":"2026-11-01"},"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).
