Before doing anything else \"loolforkit\" checks, if it was invoked by the \"lool\" user, and refuses to run with privileges, if it's not the case. In the vulnerable version of \"loolforkit\" this check was wrong, so a normal user could start \"loolforkit\" and eventually get local root privileges.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-269"],"references":["https://github.com/CollaboraOnline/online/security/advisories/GHSA-49w3-gr3w-m68v","https://www.openwall.com/lists/oss-security/2021/01/18/3","https://github.com/CollaboraOnline/online/security/advisories/GHSA-49w3-gr3w-m68v","https://www.openwall.com/lists/oss-security/2021/01/18/3"],"products":["collaboraoffice:online"],"source":"nvd","synced_at":"2026-10-19T21:15:50.279857260+00:00"},"epss":{"cve":"CVE-2021-25630","score":0.00309,"percentile":0.23774,"date":"2026-10-31"},"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).
