CVE-2022-43550: 
NixOS vulnerability analysis and mitigation

A command injection vulnerability was identified in Jitsi before commit 8aa7be58522f4264078d54752aae5483bfd854b2. The vulnerability specifically affects the browser launching functionality on Windows systems, where an attacker could potentially insert an arbitrary URL, leading to remote execution capabilities (NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. The issue is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command) and CWE-78 (Improper Neutralization of Special Elements used in an OS Command Injection) (NVD).

If successfully exploited, this vulnerability could allow an attacker to execute arbitrary commands on the target system through the browser launching mechanism, potentially leading to complete system compromise with high impacts on confidentiality, integrity, and availability (NVD).

The vulnerability has been patched in commit 8aa7be58522f4264078d54752aae5483bfd854b2, which adds a validation check to ensure that only valid HTTP links can be opened in the browser. The fix includes verification that the URL starts with 'http' before proceeding with the browser launch (Jitsi Patch).
