curl: Path Traversal in curl file:// Protocol Handler Allows Unauthorized File Access

Summary During my manual review of the file path handling logic in curl's source code, I noticed the absence of proper validation for directory traversal sequences, which I then verified through practical testing. I discovered that curl allows unauthorized access to arbitrary files through the...

curl: Alt-Svc bypasses credential leak protection (CVE-2018-1000007)

Summary I found a bug where curl's Alt-Svc implementation fails to strip sensitive authentication headers Authorization and Cookies when remapping a connection to a different host or port. This essentially bypasses the security fix for CVE-2018-1000007. While auditing the code, I noticed that...

curl: CRLF Injection in Gopher Protocol (`lib/gopher.c`)

Control characters slip through during URL handling in curl’s Gopher setup. Though null bytes get blocked by the REJECTZERO setting, returns and line feeds remain permitted. A specially built address using percent-encoded breaks - like %0D%0A - opens room for command insertion. Because of how...

curl: HTTP Request Smuggling and SSRF via CRLF Injection in Curl_add_custom_headers

Summary: A lack of CRLF validation in Curladdcustomheaders at lib/http.c:1761 allows users to inject arbitrary HTTP headers. This violation of RFC 7230 §3.2.4 leads to HTTP Request Smuggling and potential SSRF bypass. AI Disclosure: I utilized an AI assistant to aid in the initial code analysis a...

CVE-2025-34469

Cowrie versions prior to 2.9.0 contain a server-side request forgery SSRF vulnerability in the emulated shell implementation of wget and curl. In the default emulated shell configuration, these command emulations perform real outbound HTTP requests to attacker-supplied destinations. Because no...

CVE-2025-34469

CVE-2025-34469 affects Cowrie before 2.9.0. In emulated shell mode, the wget and curl commands perform real outbound HTTP requests, enabling unauthenticated attackers to generate unbounded traffic to arbitrary targets. This SSRF can turn the Cowrie honeypot into a denial-of-service amplification ...
