CVE-2026-31985 Disabled and non-configurable TLS certificate validation in n2os-tui when connecting the Remote Collector to a Guardian or CMC, in Remote Collector before v26.2.0

When the upstream Guardian or CMC was configured in the Remote Collector via n2os-tui, the generated configuration disabled TLS certificate verification, and no option was provided to enable it. A malicious actor could perform a man-in-the-middle attack and intercept the communication between the...

PYSEC-2026-901 Apache Pulsar Disabled Certificate Validation for OAuth Client Credential Requests makes C++/Python Clients vulnerable to MITM attack

The Apache Pulsar C++ Client does not verify peer TLS certificates when making HTTPS calls for the OAuth2.0 Client Credential Flow, even when tlsAllowInsecureConnection is disabled via configuration. This vulnerability allows an attacker to perform a man in the middle attack and intercept and/or...

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...

CVE-2026-12249

Canonical ADSys upstream versions up to v0.16.2 expose a flaw in AD CS auto-enrollment where the vendored Samba client uses plaintext HTTP (GETCACert) to fetch the CA certificate, enabling a network attacker in a MITM position to supply an attacker-controlled Root CA. This leads to automatic enro...

CVE-2026-12566

The dockerpull module uses the realm parameter from a Docker registry's WWW-Authenticate response header as the authentication endpoint without validation. An attacker in a man-in-the-middle position between bbot and a Docker registry could modify this header to redirect the authentication reques...

📄 Check Point VPN IKE Logic Flaw

This is a Python script attempting to exploit a vulnerability in Check Point VPN by sending a malformed IKESAINIT packet to UDP port 500, detecting whether the target responds as an indicator of exploitability, then executing a MITM attack to intercept IKE packets between a victim and a VPN...

GHSA-8G5P-JXP9-457C Assisted Migration Agent: Hardcoded insecure Transport Layer Security (TLS) connections during vCenter communication

A flaw was found in assisted-migration-agent. The application hardcodes insecure Transport Layer Security TLS connections when communicating with vCenter. This vulnerability allows a Man-in-the-Middle MITM attacker to intercept and harvest vCenter administrator credentials. This can lead to...

CVE-2026-0270: Improper Limitation of a Pathname to a Restricted Directory

A path traversal vulnerability in Palo Alto Networks Cortex XSOAR engine software running on Linux allows an unauthenticated attacker on an adjacent network, with the ability to intercept and manipulate network response traffic via a man-in-the-middle MITM attack, to write arbitrary files to the...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference in OSSLCRMFENCRYPTEDVALUEdecrypt. An attacker in a MitM position can return a CRMF CertRepMessage whose EncryptedValue carries a symmAlg field with an algorithm OID but no parameters, dereferencing NULL when the...
