CVE-2022-26850 is a medium-severity vulnerability affecting Apache NiFi versions prior to 1.16.0. It involves NiFi temporarily writing a copy of the Login Identity Providers configuration to the operating system's temporary directory, which often has global read permissions, during credential creation or updates. While the file is quickly moved, this creates a brief window where sensitive information could be exposed. The vulnerability has a CVSS score of 4.3 (Medium) due to low confidentiality impact, requiring authenticated access (PR:L), and no user interaction (UI:N). There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
