CVE-2026-14933
Cross-site scripting in the embedded co-browsing feature in Unblu inc.
Overview
CVE-2026-14933 is a known-severity vulnerability. It was published on October 20, 2026.
Technical description
Cross-site scripting in the embedded co-browsing feature in Unblu inc. Unblu Spark 7.0 through 7.57.7 and 8.0 through 8.39.2, on on-premises and cloud deployments, allows an unauthenticated remote attacker in the visitor role to execute arbitrary JavaScript in the browser of an agent taking part in the attacker's co-browsing session, via content of the co-browsed page that the agent's browser renders as HTML.
The JavaScript runs in the context and under the identity of the agent's session in the Agent Desk or the Single Conversation Desk.
Exploitation requires an agent to join an embedded co-browsing session with the attacker. Mobile co-apping isn't affected.
