Axios has Unrestricted Cloud Metadata Exfiltration via Header Injection Chain

Vulnerability Disclosure: Unrestricted Cloud Metadata Exfiltration via Header Injection Chain Summary The Axios library is vulnerable to a specific gadget-style attack chain in which prototype pollution in a third-party dependency may be leveraged to inject unsanitized header values into outbound...

cpython: Header injection via newlines in data URL mediatype in Python

Missing newline filtering has been discovered in Python. User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in the data URL mediatype...

cpython: email header injection due to unquoted newlines

A flaw was found in the email module in the Python standard library. When serializing an email message, the BytesGenerator class fails to properly quote newline characters for email headers. This issue is exploitable when the LiteralHeader class is used as it does not respect email folding rules,...

cpython: wsgiref.headers.Headers allows header newline injection in Python

Missing newline filtering has been discovered in Python. User-controlled header names and values containing newlines can allow injecting HTTP headers...

cpython: Missing character filtering in Python

Missing character filtering has been discovered in Python. When folding a long comment in an email header containing exclusively unfoldable characters, the parenthesis would not be preserved. This could be used for injecting headers into email messages where addresses are user-controlled and not...

CVE-2026-40175

The Axios HTTP client, used in both browsers and Node.js, is vulnerable to a specific gadget-style attack chain in versions prior to 1.15.0 and 0.3.1 . The root cause is prototype pollution in a third-party dependency, which can be leveraged to inject unsanitized header values into outbound reque...

busybox: BusyBox wget: HTTP request-target allows header injection

A flaw was found in BusyBox wget. This vulnerability allows header injection via raw CR/LF and other C0 control bytes in the HTTP request-target. An attacker can exploit this by crafting a URL containing these control characters to inject arbitrary HTTP headers into the outgoing request,...
