openssl_encrypt versions before 1.4.9 fail to validate server URLs in login and register_with_email functions, accepting unencrypted http:// URLs and unconfigured hosts. Attackers on the network path can intercept cleartext credentials including client_id, passwords, and JWTs to achieve full keyserver account takeover.

CVE-2026-198546.1 MED—
———When the ClickHouse plugin uses Native protocol (the default) with PDC or secure SOCKS, it asks for TLS but the connection library ignores that and talks to ClickHouse in the clear. Username, password, queries, and results can be read on the hop after the proxy. The server certificate is never checked, and a configured client certificate is not sent.6hCVE-2026-797795.3 MED1.3%
——0rclone versions before v1.75.0 fail to reject transport downgrades in redirect handling, allowing Basic authorization and Cookie headers to be replayed over plaintext HTTP after same-host HTTPS-to-HTTP redirects. An on-path attacker observing the plaintext hop can capture and reuse credentials to perform WebDAV operations with the compromised account's permissions.6hCVE-2026-12556—4.6%
——1Potential security vulnerabilities have been identified in HP Easy Start for macOS, versions prior to 2.16.7.260722. These potential vulnerabilities may lead to escalation of privilege. HP is releasing updates to mitigate these potential vulnerabilities.9hCVE-2026-19683—21.2%
——6A vulnerability exists in the Dynamic DNS (DDNS) functionality of TP-Link Omada Gateways. During communication with a third-party DDNS service, authentication credentials are transmitted over an unencrypted channel. An attacker who can observe or manipulate traffic between an affected device and the DDNS service may obtain sensitive authentication information or interfere with DDNS update operations. Exploitation requires DDNS to be configured, communication with an external DDNS service, and attacker visibility or control of the relevant network path.
Successful exploitation may result in disclosure of DDNS account credentials, unauthorized access to DDNS management functionality, or modification of DNS records associated with the affected deployment.7dCVE-2026-2230610.0 CRÍ4.8%
——1Download of code without integrity check, inclusion of functionality from untrusted control sphere, and cleartext
transmission of sensitive information vulnerability in Ozols Grupa OZOLS
on Windows caused by an abandoned auto-update domain. Affected
component: the automatic update channel - OzolsSQL client update path, the <db>_update SQL Server Agent job (@subsystem = N'ActiveScripting') and serv_update.vbs.
This issue affects OZOLS: before 1.1.1233.1dCVE-2026-76244—11.9%
——4stigmem-node contains an insecure default configuration vulnerability that allows federation traffic to traverse networks without mTLS protection when non-loopback endpoints are enabled. Operators who explicitly disabled mTLS while binding federation to non-loopback addresses expose federation traffic to cleartext interception and man-in-the-middle attacks.8d
