Medium (6.3) in omnispace agora project.
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.

Explain CVE-2026-63170 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-63170?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-63170?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-63170 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
