Omnispace Agora Project < 26.10.0 Stored XSS via Nested POST Array Bypass

Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to persist unneutralized markup by submitting malicious values as two-dimensional POST arrays through the LDAP/person import flow, bypassing the paramsFilter() request parameter filter which failed to recurse into nested arrays. Attackers can inject arbitrary script code into a user profile that is later rendered to other users, resulting in execution of malicious scripts in victims' browsers.
