Prior to 1.1.35, the executor-legacy-ws buildWSLegacyExecutor() function hardcodes TLS certificate rejection off for Node.js connections to wss:// endpoints. Applications using the executor directly, or url-loader with SubscriptionProtocol.LEGACY_WS, can therefore accept an attacker-controlled certificate when a network-positioned attacker intercepts the connection. Authentication material in connectionParams or headers can be disclosed, and subscription data can be modified. Browser WebSocket clients are unaffected because browsers enforce certificate validation. This issue is fixed in version 1.1.35."

In multi-tenant services or SNI-routed SMTP gateways, an attacker who can prime the cache can cause a victim transport to connect to the attacker\u0027s TLS virtual host and accept the attacker\u0027s certificate even with rejectUnauthorized: true, disclosing the victim\u0027s SMTP credentials.

While native connections enforced the saved Gateway fingerprint, the authenticated Terminal and session Dashboard WebViews omitted it. If a user had accepted a Gateway fingerprint, an attacker able to redirect the same host and port and present a different certificate that is accepted by iOS system trust can serve a replacement Control UI page; opening the Terminal or a session Dashboard then allows that page to read the injected Gateway token or password. The stolen credential can grant operator access, including reading sensitive Gateway state and invoking host-capable tools. This issue is fixed in 2026.8.11."

The trigger is that an application uses an HTTPS proxy and configures target-server TLS settings that must remain separate from the proxy TLS handshake, including HTTPS forwarding with target-specific identity or credentials. Applying cert_reqs=CERT_NONE can overwrite proxy_ssl_context.verify_mode in place, and the mutation persists so later connections reusing the same context may connect to the HTTPS proxy without certificate verification. The attack mechanism is that an attacker intercepts and impersonates the HTTPS proxy after the effective proxy policy accepts the attacker\u0027s certificate. The impact is that the attacker can observe or modify forwarded traffic or receive a target TLS client certificate, while CONNECT tunneling still preserves the separate end-to-end target TLS connection. This issue is fixed in version 2.8.0."
