The Dashboard API, by contrast, uses an indexOf\u2011based comparison that correctly prevents users from creating accounts at or above their own rank. This inconsistency allows an authenticated admin to create additional admin accounts through the REST API, thereby increasing the number and persistence of privileged accounts. The vulnerability is classified as CWE\u2011269 (Elevation of Privilege). The impact is confined to privilege escalation and does not explicitly state that additional functions such as content exfiltration are possible.", "risk_and_exploitability": "The CVSS base score is 4.7, indicating moderate severity. The EPSS score is less than 1%, and the vulnerability is not listed in the CISA KEV catalog.
