OpenClaw < 2026.4.2 - Cleartext Credential Transmission via Unencrypted WebSocket Gateway Endpoints

OpenClaw before 2026.4.2 accepts non-loopback cleartext ws:// gateway endpoints and transmits stored gateway credentials over unencrypted connections. Attackers can forge discovery results or craft setup codes to redirect clients to malicious endpoints, disclosing plaintext gateway credentials.

Shenzhen HCC Technology MPOS M6 PLUS Cardholder Data cleartext transmission

A flaw has been found in Shenzhen HCC Technology MPOS M6 PLUS 1V.31-N. This affects an unknown part of the component Cardholder Data Handler. Executing a manipulation can lead to cleartext transmission of sensitive information. The attack requires access to the local network. The attack requires a high level of complexity. It is indicated that the exploitability is difficult. The vendor was contacted early about this disclosure but did not respond in any way.

Unencrypted Client‑Server Communication in ConnectWise Automate™ Solution Center

ConnectWise has released a security update for ConnectWise Automate™ that addresses a behavior in the ConnectWise Automate Solution Center where certain client-to-server communications could occur without transport-layer encryption. This could allow network‑based interception of Solution Center traffic in Automate deployments. The issue has been resolved in Automate 2026.4 by enforcing secure communication for affected Solution Center connections.

The Cisco Linksys WVC54GC wireless video camera before firmware 1.25 sends cleartext configuration data in response to a Setup Wizard remote-management command, which allows remote attackers to obtain sensitive information such as passwords by sniffing the network.

make_catalog_backup in Bacula 2.2.5, and probably earlier, sends a MySQL password as a command line argument, and sometimes transmits cleartext e-mail containing this command line, which allows context-dependent attackers to obtain the password by listing the process and its arguments, or by sniffing the network.

OKI C5510MFP Printer CU H2.15, PU 01.03.01, System F/W 1.01, and Web Page 1.00 sends the configuration of the printer in cleartext, which allows remote attackers to obtain the administrative password by connecting to TCP port 5548 or 7777.

EMC Dantz Retrospect Backup Client 7.5.116 sends the password hash in cleartext at an unspecified point, which allows remote attackers to obtain sensitive information via a crafted packet.

Cisco Adaptive Security Appliance (ASA) running PIX 7.0 before 7.0.7.1, 7.1 before 7.1.2.61, 7.2 before 7.2.2.34, and 8.0 before 8.0.2.11, when AAA is enabled, composes %ASA-5-111008 messages from the "test aaa" command with cleartext passwords and sends them over the network to a remote syslog server or places them in a local logging buffer, which allows context-dependent attackers to obtain sensitive information.

Joomla! 1.5.8 does not set the secure flag for the session cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

Cryptomator Hub OAuth token exchange HTTP downgrade via getAuthority() scheme confusion (CVE-2026-32303 bypass)

Cryptomator is an open-source client-side encryption application for cloud storage. Version 1.19.1 contains a logic flaw in CheckHostTrustController.getAuthority() that allows an attacker to bypass the security fix for CVE-2026-32303. The method hardcodes the URI scheme based on port number, causing HTTPS URLs with port 80 to produce the same authority string as HTTP URLs, which defeats both the consistency check and the HTTP block validation. An attacker with write access to a cloud-synced vault.cryptomator file can craft a Hub configuration where apiBaseUrl and authEndpoint use HTTPS with port 80 to pass auto-trust validation, while tokenEndpoint uses plaintext HTTP. The vault is auto-trusted without user prompt, and a network-positioned attacker can intercept the OAuth token exchange to access the Cryptomator Hub API as the victim. This issue has been fixed in version 1.19.2.

HCL BigFix Service Management (SM) Discovery is vulnerable to unenforced encryption

HCL BigFix Service Management (SM) Discovery is vulnerable to unenforced encryption due to port 80 (HTTP) being open, allowing unencrypted access.  An attacker with access to the network traffic can sniff packets from the connection and uncover the data.

SNI was sometimes unencrypted

In certain cases, SNI could have been sent unencrypted even when encrypted DNS was enabled. This vulnerability was fixed in Firefox 139 and Thunderbird 139.

Cleartext transmission of sensitive materials in aws/sagemaker-python-sdk

The Amazon SageMaker Python SDK before v3.2.0 and v2.256.0 includes the ModelBuilder HMAC signing key in the cleartext response elements of the DescribeTrainingJob function. A third party with permissions to both call this API and permissions to modify objects in the Training Jobs S3 output location may have the ability to upload arbitrary artifacts which are executed the next time the Training Job is invoked.

Micca KE700 Cleartext transmission of key fob ID

The RF communication protocol in the Micca KE700 car alarm system does not encrypt its data frames. An attacker with a radio interception tool (e.g., SDR) can capture the random number and counters transmitted in cleartext, which is sensitive information required for authentication.

Jinan USR IOT Technology Limited (PUSR) USR-W610 Cleartext Transmission of Sensitive Information

The embedded web interface of the device does not support HTTPS/TLS for authentication and uses HTTP Basic Authentication. Traffic is encoded but not encrypted, exposing user credentials to passive interception by attackers on the same network.

EXCHANGE OF CREDENTIALS IN CLEAR TEXT

An attacker with a network connection could detect credentials in clear text.

Cleartext Transmission Vulnerability in Tenda Wireless Routers

This vulnerability exists in Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) due to the plaintext transmission of login credentials during the initial login or post-factory reset setup through the web-based administrative interface. An attacker on the same network could exploit this vulnerability by intercepting network traffic and capturing the credentials transmitted in plaintext. Successful exploitation of this vulnerability could allow the attacker to obtain sensitive information and gain unauthorized access to the targeted device.

Insecure Transmission Vulnerability in Tenda Wireless Routers

This vulnerability exists in Tenda wireless routers (300Mbps Wireless Router F3 and N300 Easy Setup Router) due to the transmission of credentials encoded using reversible Base64 encoding through the web-based administrative interface. An attacker on the same network could exploit this vulnerability by intercepting network traffic and capturing the Base64-encoded credentials. Successful exploitation of this vulnerability could allow the attacker to obtain sensitive information and gain unauthorized access to the targeted device.

Cleartext Transmission of Sensitive Information in Dell ECS and ObjectScale

Dell ECS, versions 3.8.1.0 through 3.8.1.7, and Dell ObjectScale versions prior to 4.2.0.0, contains a Cleartext Transmission of Sensitive Information vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information exposure.
