CVE-2023-48226Public exploitNetwork attack vector

Phishing via unsanitized invitation-email sender name

Published Nov 21, 2023 · Updated Aug 2, 2024

HTML injection in OpenReplay 1.14.0 allows remote authenticated users to embed attacker-controlled links in invitation emails. The Account Settings Name value is stored without validation and inserted into api/chalicelib/utils/html/invitation.html as HTML when an invitation is generated. A valid account and an invitation recipient are required; the trusted-origin email can spoof content and direct recipients to phishing sites.
