This vulnerability involves improper neutralization of input during web page generation in useStrict's Calendly Embedder (cal-embedder-lite), leading to Stored Cross-site Scripting (XSS). It affects versions up to 1.1.7.2. The CVSS 3.1 base score is 5.9, indicating a medium severity with network attack vector, low attack complexity, high privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at a low level. No patch or remediation guidance is currently provided by the vendor or in the advisory.

Successful exploitation could allow an attacker with high privileges and requiring user interaction to inject and store malicious scripts that execute in the context of other users, potentially leading to limited confidentiality, integrity, and availability impacts. However, no known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution with input handling and consider limiting privileges where possible. Monitor vendor communications for updates on patches or official mitigations.
