PILOS, a frontend for BigBlueButton, versions from 2.1.0 up to but not including 4.14.1, does not set the Cross-Origin-Opener-Policy header. This allows pages opened with target="_blank" to retain a window.opener reference, enabling reverse tabnabbing attacks where a malicious page can manipulate the original PILOS tab. The issue is fixed in version 4.14.1.
