Technical description
A Server-Side Request Forgery (SSRF) vulnerability existed in Lookyloo's PlaywrightCapture when the only_global_lookup option was enabled.
PlaywrightCapture implements this option to prevent captures from accessing local, loopback, or otherwise non-public network resources. However, favicon retrieval was performed separately from the browser request-routing protections. Favicon URLs extracted from rendered HTML were resolved and subsequently fetched directly using an aiohttp.ClientSession.
An attacker able to supply or control a web page processed by PlaywrightCapture could include a crafted favicon reference, for example pointing to a loopback address, private IP address, or another resource reachable only from the PlaywrightCapture host. When the page was processed, the favicon retrieval routine could issue an HTTP request to this destination despite only_global_lookup being enabled.
This bypass could therefore be used to make the PlaywrightCapture host interact with internal netw
