					<description><![CDATA[A vulnerable chat overlay, an unsandboxed Chromium renderer, and a V8 bug already exploited in the wild were enough to turn viewer-controlled text into native code execution, with OBS itself left at its default settings. I found a Twitch chat overlay that rendered viewer messages as raw HTML inside an OBS Browser Source.

					<description><![CDATA[In November 2022, an advisory was published by Microsoft about a BitLocker bypass. This vulnerability caught my attention because the fix required a manual operation by users and system administrators, even after installing all the security updates. Couple this with the fact that the procedure was not well documented initially, and you have the perfect &#8230; <a href="/2023/08/14/cve-2022-41099-analysis-of-a-bitlocker-drive-encryption-bypass/" class="more-link">Continue reading <span class="screen-reader-text">CVE-2022-41099 &#8211; Analysis of a BitLocker Drive Encryption Bypass</span></a>]]></description>

Given the relative lack of information surrounding it at the time, and the fact I&#8217;d have some uninterrupted research time due to a lengthy flight, I decided to attempt to produce a POC for the vulnerability.
