F‑Secure SAFE Browser is susceptible to sandboxing bypass even when sandboxed-navigation-browsing-context flag has been set. This happens because nested browsing context within an iframe did not inherit the flag as expected. This could lead to potentially malicious content being loaded within the iframe.
This issue was reported to F‑Secure through the Vulnerability Reward Program. No known exploit or attack has been seen in the wild.
