Description

This security bulletin contains information about 1 vulnerability.


1) Information disclosure (CVE-ID: CVE-2026-40895)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to exposure of sensitive information in the redirect handling logic in index.js when following cross-domain redirects. A remote attacker can cause a request to be redirected to an attacker-controlled domain to disclose sensitive information.

Custom authentication headers such as API keys or auth tokens may be forwarded to the redirect target, while only authorization, proxy-authorization, and cookie headers are stripped.
