HIGHPre-NVD 7.17.1—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 57% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

TypeBot is a chatbot builder tool. Prior to version 3.17.0, an authenticated user who has read access to any typebot can resume a waiting webhook session that belongs to a different typebot by mixing an authorized typebotId and blockId and a foreign live resultId. The webhook resume handler authorizes the parent typebot first, but then resolves the descendant result only by resultId. As a result, an attacker can inject arbitrary webhook JSON into another typebot's suspended session and advance its execution without any access to the victim typebot. Version 3.17.0 patches the issue.
