PILOS (Platform for Interactive Live-Online Seminars) is a frontend for BigBlueButton. PILOS before 4.8.0 includes a Cross-Origin Resource Sharing (CORS) misconfiguration in its middleware: it reflects the Origin request header back in the Access-Control-Allow-Origin response header without proper validation or a whitelist, while Access-Control-Allow-Credentials is set to true. This behavior could allow a malicious website on a different origin to send requests (including credentials) to the PILOS API. This may enable exfiltration or actions using the victim’s credentials if the server accepts those cross-origin requests as authenticated. Laravel’s session handling applies additional origin checks such that cross-origin requests are not authenticated by default. Because of these session-origin protections, and in the absence of any other unknown vulnerabilities that would bypass Laravel’s origin/session checks, this reflected-Origin CORS misconfiguration is not believed to be exploitable in typical PILOS deployments. This vulnerability has been patched in PILOS in v4.8.0

CORS misconfiguration in CoolerControl/coolercontrold <4.0.0 allows unauthenticated remote attackers to read data and send commands to the service via malicious websites

A flaw has been found in CodeCanyon/ui-lib Mentor LMS up to 1.1.1. Affected by this vulnerability is an unknown functionality of the component API. Executing manipulation can lead to permissive cross-domain policy with untrusted domains. The attack may be launched remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Hush Line is a free and open-source, anonymous-tip-line-as-a-service for organizations or individuals. The CSP policy applied on the `tips.hushline.app` website and bundled by default in this repository is trivial to bypass. This vulnerability has been patched in version 0.1.0.
