CVE-2021-25930 is a Cross-Site Request Forgery (CSRF) vulnerability affecting OpenNMS Horizon (versions 1.0-stable to 27.1.0-1) and OpenNMS Meridian (various versions from 2015.1.0-1 to 2020.1.6-1). The flaw stems from a lack of CSRF protection and insufficient validation when renaming users, allowing an attacker to overwrite a renamed user's privileges with those of the old user, effectively deleting the old user from the list. Rated Medium severity (CVSS 4.3), this vulnerability requires user interaction (UI:R) but has low impact (I:L) on integrity, with no confidentiality or availability impact. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
