CVE-2026-63170

LowCVSS 3.7/10Last modified Nov 13, 2026

Description

Omnispace Agora Project through 26.10.0 contains a predictable token generation vulnerability that allows unauthenticated attackers to forge the shared-calendar iCal share token by deriving md5Id() from predictable fields such as object creation time, which is self-disclosed through autorDate and the iCal CREATED field. Attackers can compute the creation minute and forge the md5Id token to access and read a shared calendar's iCal feed without authorization.
