curl: CVE-2026-11586: WS Auto-PONG memory exhaustion

Summary: TL;DR: a remote WebSocket peer can make default curl/libcurl grow memory until timeout or OOM by sending legal PING frames while refusing to read the client's automatic PONGs. curl automatically replies to each received WebSocket PING with a PONG unless CURLWSNOAUTOPONG is set. In...

curl: SSH/SFTP connection reuse can bypass SSH key identity after ssh_config_matches removal

Summary: libcurl's SSH/SFTP connection reuse logic no longer binds a pooled SSH connection to the SSH key identity requested by the new transfer. After sshconfigmatches was removed, urlmatchprotoconfig again has no SSH-specific check for CURLOPTSSHPUBLICKEYFILE or CURLOPTSSHPRIVATEKEYFILE. An...

curl: SOCKS5 no-auth accepted despite username/password-only authentication

Summary: curl/libcurl appears to allow unauthenticated SOCKS5 negotiation even when the caller explicitly configures username/password-only SOCKS5 authentication. With --socks5-basic and SOCKS5 credentials set, curl still advertises both SOCKS5 method 0x00 no authentication and 0x02...

curl: libcurl: HTTP/1.x bare LF byte in response header value enables cookie jar pollution and POST body/credential exfiltration via redirect — RC=0, curl 8

Summary curl's HTTP/1.x response header parser splits header lines using a single memchrbuf, '\n', blen call lib/http.c:4457, with no awareness of whether the current position is inside a quoted-string value. A server response containing any header field whose value embeds a raw LF byte \x0a caus...
