Summary

CVE-2023-6206 is a vulnerability affecting Firefox versions below 120, Firefox ESR below 115.5.0, and Thunderbird below 115.5. The black fade animation during fullscreen exit lasts approximately as long as the anti-clickjacking delay on permission prompts. Maliciously crafted content could exploit this timing difference, tricking users into clicking on what appears to be a permission grant button just as it becomes visible, potentially leading to unintended actions or data disclosure.
