CVE-2026-71555: CWE-1022: Use of Web Link to Untrusted Target with window.opener Access in THM-Health PILOSCVE-2026-71555 0 PILOS, a frontend for BigBlueButton, versions from 2.1.0 up to but not including 4.14.1, does not send a Cross-Origin-Opener-Policy header. This allows pages opened with target="_blank" to retain a window.opener reference to the original PILOS tab. A malicious page opened this way can manipulate the original tab via reverse tabnabbing, potentially redirecting authenticated users to phishing pages. The issue is fixed in version 4.14.1.
