A flaw was found in the SMTP email configuration handling of the keycloak-services component. When the STARTTLS option is enabled, Keycloak fails to strictly enforce an encrypted connection, allowing it to fall back to unencrypted communication if the encryption request is tampered with. An attacker who can intercept network traffic can exploit this to capture sensitive email credentials and message content in plain text.

——0VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains a cleartext traffic vulnerability that allows network-based attackers to intercept or modify unencrypted HTTP communications due to the absence of an Android network security configuration. Attackers on an untrusted network can manipulate support content displayed to the user by tampering with unencrypted HTTP traffic between the app and server.13hCVE-2026-120734—1.9%
——1Cleartext transmission of sensitive information in the email configuration test in Devolutions Server 2026.3.13.0 and earlier allows an authenticated user with access to the test action to obtain the stored SMTP password via a request that names an attacker-controlled SMTP host.2dCVE-2026-1183733.7 BAI0.4%
——0LibreSSL ocspcheck through 4.4.0 contains a cleartext transmission vulnerability because url2host() discards the OCSP URL scheme and http_alloc() only selects TLS for port 443. On-path network attackers can read OCSP requests sent to https responder URLs on non-443 ports, exposing certificate serial numbers, issuer hashes, and nonces.12hCVE-2026-115495—0.1%
——0Cleartext Transmission of Sensitive Information vulnerability in the WatchGuard Mobile VPN with SSL client for Windows allows a local attacker who can capture loopback traffic to obtain the user’s VPN username and password.1dCVE-2026-1168444.8 MÉD0.4%
——0Fclairamb ftpserverlib through 0.32.4 contains a cleartext transmission vulnerability because TransferOpen checks only the transferTLS flag set by PROT, not whether the prepared data connection uses TLS. When a client sends PROT P after PASV or PORT, file contents and directory listings cross the network unencrypted, even with mandatory encryption, letting on-path attackers read or modify them.8dCVE-2026-703796.5 MÉD1.4%
——0When the vSolution Matrix feature is enabled, affected devices may make current screen content available through an unauthenticated RTSP/RTP stream to hosts on the same network segment. The stream is not encrypted, which may allow an unauthenticated host to view or capture presentation content where network access is not otherwise restricted. This vulnerability only affects devices with the vSolution Matrix feature enabled.3d
