On most platforms, the operating system temporary directory has global read permissions. NiFi immediately moved the temporary file to the final configuration directory, which significantly limited the window of opportunity for access. NiFi 1.16.0 includes updates to replace the Login Identity Providers configuration without writing a file to the operating system temporary directory.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-668"],"references":["http://www.openwall.com/lists/oss-security/2022/04/06/2","https://nifi.apache.org/security.html#CVE-2022-26850","http://www.openwall.com/lists/oss-security/2022/04/06/2","https://nifi.apache.org/security.html#CVE-2022-26850"],"products":["apache:nifi"],"source":"nvd","synced_at":"2026-10-19T21:29:06.454770966+00:00"},"epss":{"cve":"CVE-2022-26850","score":0.01493,"percentile":0.74146,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-rvp4-r3g6-8hxq","url":"https://osv.dev/vulnerability/GHSA-rvp4-r3g6-8hxq","summary":"Insufficiently Protected Credentials via Insecure Temporary File in org.apache.nifi:nifi-single-user-utils","modified":"2025-09-15T07:41:59.149471Z","packages":[{"ecosystem":"Maven","name":"org.apache.nifi:nifi-single-user-utils","purl":"pkg:maven/org.apache.nifi/nifi-single-user-utils","ranges":["<1.16"],"fixed":["1.16"]}]}],"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).
