Executive Summary

The EthPress – Web3 Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.5. This is due to the verify_login() function in app/Login.php containing a missing return statement in the signature verification failure branch — when Signature::verify2() reports a mismatch, the function only assigns a WP_Error to a local variable and continues executi

Analysis

The EthPress – Web3 Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.5. This is due to the verify_login() function in app/Login.php containing a missing return statement in the signature verification failure branch — when Signature::verify2() reports a mismatch, the function only assigns a WP_Error to a local variable and continues executing, causing unconditional fall-through to the login block where Address::log_in() calls wp_set_auth_cookie() regardless of whether the submitted signature is valid. This makes it possible for unauthenticated attackers to log in as any WordPress user who has a linked wallet address — including administrators — by submitting that user's public wallet address alongside an arbitrary well-formed signature, enabling full site takeover. CVSS Score: 8.1. Published: 2026-09-23T22:16:56.683.

A flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a cl

Mooncake through 0.3.13.post1 contains a missing authentication vulnerability in the HTTP metadata server /metadata handler that allows unauthenticated attackers to read, overwrite, and delete transfer engine metadata keys. Attackers can poison segment descriptors such as tcp_data_port or re-create rpc_meta entries to redirect KV cache transfers to attacker-controlled listeners, or exhaust server

Mooncake transfer engine before 0.3.13 contains an untrusted pointer dereference in ServerSession::readHeader that allows unauthenticated attackers to read and write arbitrary process memory via the TCP transport data port. Attackers can send a crafted SessionHeader with arbitrary addr and size values using READ or WRITE opcodes to disclose KV cache contents, prompts and secrets or corrupt memory
