CVE-2025-14819 OpenSSL partial chain store policy bypass

When doing TLS related transfers with reused easy or multi handles and altering the CURLSSLOPTNOPARTIALCHAIN option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcur...

curl: Malicious server forces .curlrc creation via curl -OJ leading to local file exfiltration

Summary: When a user runs curl -OJ , a malicious server can force the response to be saved as .curlrc in the working directory. If the user executes the download from their home directory a common workflow, the attacker overwrites /.curlrc. Subsequent curl invocations automatically load this...

CVE-2022-31090 CURLOPT_HTTPAUTH option not cleared on change of origin in Guzzle

Guzzle, an extensible PHP HTTP client. Authorization headers on requests are sensitive information. In affected versions when using our Curl handler, it is possible to use the CURLOPTHTTPAUTH option to specify an Authorization header. On making a request which responds with a redirect to a URI wi...

CVE-2022-27781

libcurl provides the CURLOPTCERTINFO option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation...

libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`) a malicious user can create a file name with the same name as the app wants to use by name and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake.

curl: Inferior OCSP verification

Libcurl offers "OCSP stapling" via the CURLOPTSSLVERIFYSTATUS option. When set, libcurl verifies the OCSP response that a server responds with as part of the TLS handshake. It then aborts the TLS negotiation if something is wrong with the response. The same feature can be enabled with --cert-stat...
