CVE-2025-66458

Lookyloo prior to version 1.35.1 has potential cross-site scripting on index and tree pages. This issue has been patched in version 1.35.1.

A Server-Side Request Forgery (SSRF) vulnerability was found in Lookyloo's PlaywrightCapture when the only_global_lookup option is enabled. Favicon retrieval was performed outside the browser request-routing protections, allowing an attacker to send HTTP requests to internal resources (e.g., loopback, private IPs) via a crafted web page. The patch introduces a common URL validation routine for favicon retrieval, rejecting non-public destinations.

Lookyloo does not enforce limits on the decompressed size of uploaded capture archives and compressed HAR files. An attacker can submit a crafted archive that expands to a very large size, exhausting memory and causing denial of service.

Lookyloo is a web interface that allows users to capture a website page and then display a tree of domains that call each other. Prior to 1.35.3, Lookyloo passed improperly escaped values to cells rendered in datatables using the orthogonal-data feature. It is definitely exploitable from the popup view, but it is most probably also exploitable in many other places. This vulnerability is fixed in 1.35.3.

Lookyloo is a web interface that allows users to capture a website page and then display a tree of domains that call each other. Prior to 1.35.3, a XSS vulnerability can be triggered when a user submits a list of URLs to capture, one of them contains a HTML element, and the capture fails. Then, the error field is populated with an error message that contains the bad URL they tried to capture, triggering the XSS. This vulnerability is fixed in 1.35.3.
