GHSA-4VMC-GM8V-M35H Gotenberg vulnerable to unauthenticated SSRF via default deny-list bypass in downloadFrom and webhook

Summary The default deny-lists used by Gotenberg's downloadFrom feature and webhook feature are bypassable. Because the filter is regex-based and case-sensitive, an unauthenticated attacker can supply URLs such as http://::ffff:127.0.0.1:... and reach loopback or private HTTP services that the...

link-preview-js vulnerable to IPv6 and internal loopback attacks

Impact The library did not check for IPv6 loopback attacks. There was also a DNS attack, where an address could be resolved into an internal IP. This could cause internal data leaks. Patches Problem has been patched in version 4.0.1. However, it cannot be completely solved by the package alone. T...

CVE-2026-42043

A flaw was found in Axios, a promise-based HTTP client. An attacker who can control the destination address of an Axios request can exploit this vulnerability. By using specific internal network addresses within the 127.0.0.0/8 range, excluding 127.0.0.1, the attacker can completely bypass the...

CVE-2026-42038

A flaw was found in Axios, a software library used for making web requests. This vulnerability allows an attacker to bypass the noproxy configuration, which is designed to prevent certain internal network requests from being sent through an external proxy. Specifically, when noproxy=localhost is...

Proxy Bypass

Axios is vulnerable to Proxy Bypass. The vulnerability is due to incomplete NOPROXY handling for loopback addresses, where requests to the 127.0.0.0/8 range excluding 127.0.0.1 bypass proxy restrictions, allowing attackers to access internal or local services despite configured protections...

CVE-2026-42038 Axios: no_proxy bypass via IP alias allows SSRF

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, he fix for noproxy hostname normalization bypass is incomplete. When noproxy=localhost is set, requests to 127.0.0.1 and ::1 still route through the proxy instead of bypassing it. The shouldBypassProxy...
