CVE-2026-73210Network attack vector

SSRF via unchecked favicon retrieval

Published Aug 11, 2026 · Updated Aug 11, 2026

SSRF in Lookyloo PlaywrightCapture before 1.40.6 allows remote attackers to reach private HTTP services through crafted favicon URLs. With only_global_lookup enabled, get_favicons resolves an HTML favicon reference and passes it to aiohttp without the browser route's non-public URL check. Exploitation requires an attacker-controlled page to be captured; requests originate from the capture host and can interact with loopback or internal endpoints.
