———IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information and compromise system integrity due to an XML injection flaw.5hCVE-2026-561798.3 ALT—
——0Origin validation error in Windows Network Address Translation (NAT) allows an unauthorized attacker to perform spoofing over an adjacent network.6hCVE-2026-19418—11.7%
——4The referrer enforcement introduced with TYPO3-CORE-SA-2020-006 (CVE-2020-11069) became ineffective in TYPO3 v13.0, where TYPO3 CMS started serving the backend and Install Tool applications from the site's main entry script instead of the dedicated typo3/ directory.
Whether a request originated from the backend or Install Tool itself was determined by comparing the referrer against the directory of the entry script, which since then is the site root. As a consequence, requests originating from any script running on one of the TYPO3 instance's own domains, such as a frontend page, were accepted by backend routes and Install Tool endpoints.
Attackers able to execute JavaScript on one of those domains, for instance by exploiting a cross-site scripting vulnerability, could invoke these endpoints via Fetch/XHR with the privileges of an authenticated victim's user session. This issue affects TYPO3 CMS versions 13.0.0-13.4.33 and 14.0.0-14.3.5.1dCVE-2026-464099.6 CRÍ29.1%
——9OpenYak is a local-first agent runtime for reliable tool-using models, with a desktop workspace built on top. Prior to version 1.1.3, the OpenYak desktop backend binds an HTTP API to `127.0.0.1:<random port>` (commonly 19141) without server-side Origin validation, loopback authentication, or Content-Type enforcement, and with a wildcard CORS policy. Any webpage a user visits while OpenYak is running can issue cross-origin requests to this local server — the browser acts as a proxy into loopback, bypassing OS-level network isolation. Chained, this lets a malicious page execute arbitrary shell commands on the host (RCE) via the build agent with `permission_presets.bash=true`, shut down the service, and exfiltrate chat history and account PII — with no user interaction beyond opening the page. Version 1.1.3 patches the issue.2dCVE-2026-47194—10.2%
——3Frappe is a full-stack web application framework. Prior to 15.108.0 and 16.18.3, temporary magic login link generation can use an attacker-controlled request Host header, allowing a remote attacker to cause emailed login links to point to an attacker-controlled domain and capture the login token when a recipient follows the link. This issue is fixed in versions 15.108.0 and 16.18.3.5dCVE-2026-667325.9 MED2.4%
——1Sonic 3 A.I.R. before commit 2492d18 contains a missing source address validation vulnerability in ConnectionManager where established connections are resolved by a two-byte local connection handle alone without verifying that the datagram source address matches the registered remote address for the connection. An on-path attacker who can observe cleartext UDP traffic can inject arbitrary packets into any established session by forging the two-byte connection identifier, enabling session termination via TerminateConnectionPacket, arbitrary channel message forgery, and forged request responses without requiring IP address spoofing.6d
