CVE-2026-56123

CVE-2026-56123 affects socat versions 1.8.0.0 through 1.8.1.1. A signed-char sign-extension bug in the DOMAINNAME reply parser during SOCKS5 handshake allows a negative bytes_to_read value to be implicitly converted to size_t, causing an unbounded heap write into a 262-byte reply buffer. This res...

EUVD-2026-39455

socat versions 1.8.0.0 through 1.8.1.1 contain a heap-based buffer overflow vulnerability that allows a malicious SOCKS5 proxy server to overwrite adjacent heap memory by exploiting a sign-extension flaw in the DOMAINNAME reply parser. During connection setup, the domain name length byte is read...

undici vulnerable to TLS certificate validation bypass via dropped requestTls in SOCKS5 ProxyAgent

Impact undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI socks5:// or socks://. The target HTTPS connection through the SOCKS5 tunnel falls back to Node's default trust store, ignoring user-configured ca, cert, key, rejectUnauthorized, and servername...

CVE-2026-9697

A flaw was found in undici. When undici's ProxyAgent is configured with a SOCKS5 proxy Uniform Resource Identifier URI, it silently ignores Transport Layer Security TLS options, such as custom Certificate Authorities CAs. This allows a remote attacker to perform a Man-in-the-Middle MITM attack,...

Improper Certificate Validation

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Improper Certificate Validation in the ProxyAgent when configured with a SOCKS5 proxy URI, which causes the requestTls option to be silently dropped. An attacker can...

CVE-2026-9697

undici’s ProxyAgent drops the requestTls option when used with a SOCKS5 proxy (socks5:// or socks://), causing the HTTPS connection to rely on Node’s default trust store and ignore user-provided ca, cert, key, rejectUnauthorized, and servername. This allows any cert signed by a publicly trusted C...

CVE-2026-6734

Summary of CVE-2026-6734 : A vulnerability in undici’s Socks5ProxyAgent causes cross-origin request routing by reusing a single connection pool across multiple origins without verifying the pool origin. As a result, requests for origin B can be dispatched through the pool for origin A; credential...

CVE-2026-47071

Uncontrolled Resource Consumption vulnerability in benoitc hackney allows Flooding. The SOCKS5 transport in src/hackneysocks5.erl correctly applies the caller-supplied timeout to the SOCKS5 negotiation phase, but then upgrades the connection to TLS using the two-argument form ssl:connect/2, which...

JLSEC-2025-34 This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake.

This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host na...

curl: Race condition on global `gss_context` during SOCKS5 GSS-API negotiation in libcurl
