CVE-2026-12064

A flaw was found in curl. When a user invokes curl with a schemeless URL and specifies SFTP SSH File Transfer Protocol or SCP Secure Copy Protocol as the default protocol, the tool layer fails to initialize critical SSH security options. This bypasses host verification, allowing curl to connect t...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the aibridgeproxyd process when the default transport is configured with InsecureSkipVerify: true, causing outbound HTTPS connections to accept any TLS certificate. An attacker can intercept sensitive...

GHSA-84RM-42XW-MX52 Coder's AI Bridge Proxy skips TLS certificate verification in default configuration

Summary The AI Bridge Proxy aibridgeproxyd created a goproxy server whose default transport set InsecureSkipVerify: true and only assigned a secure transport when an upstream proxy was configured. In the default configuration no upstream proxy, outbound HTTPS to the Coder access URL accepted any...

CVE-2026-54291

pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to...

CVE-2026-54291 Silent channel-binding authentication downgrade via unsupported certificate algorithms

pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to...

CVE-2026-54291

CVE-2026-54291 affects pgjdbc (OpenJDK PostgreSQL JDBC Driver) in versions 42.7.4–42.7.11. The issue allows a silent downgrade of channelBinding from SCRAM-SHA-256-PLUS to plain SCRAM-SHA-256 when an attacker can intercept TLS and presents a certificate whose signature algorithm lacks a tls-serve...

undici: undici: Man-in-the-Middle attack via ignored TLS options with SOCKS5 proxy

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,...

net-imap: ruby: Net::IMAP: Information disclosure via man-in-the-middle attack bypassing TLS

A flaw was found in the Ruby net-imap library. When upgrading a cleartext IMAP connection to TLS using the Net::IMAPstarttls method, the library improperly handles certain responses received during STARTTLS negotiation. A man-in-the-middle MITM attacker can inject a predicted tagged OK response...
