Attackers can log in to accounts that have no password, such as SSH key-only accounts, on some Alpine Linux servers running the standard openssh-server package. They need network access to the server, an account name, and a password between 257 and 1,024 bytes long. OpenSSH, which rates the flaw critical, released version 10.6p2 today to block it. Alpine has published fixed packages for every

CISA, the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) and the National Security Agency (NSA) released joint guidance and an accompanying quick-reference list to help organizations assess vendor readiness for transitioning to post-quantum cryptography (PQC). As quantum computing advances, widely used public-key cryptography will become vulnerable to compromise from cryptographically relevant quantum computers (CRQCs). To protect their systems and data, organizations must plan for and transition to PQC—which includes algorithms capable of withstanding both classical computing and quantum-enabled threats—before CRQCs become available. Many organizations rely on third-party vendors for managed services, cloud capabilities, and other cryptography-dependent products and services. Cryptography is also embedded in systems and devices that are difficult to update, tied to long asset lifecycles, and require vendor support or replacement—such as industrial control systems and Internet of Things (IoT) devices. Reliance on vendors means that effective PQC transition depends on vendor readiness, and early, structured engagement with these vendors is critical to planning efforts. Organizations can use the vendor-neutral questions outlined in this guidance to determine whether a vendor understands quantum-related risks, maintains transparency over its cryptographic implementations, and supports a secure, cost-effective and timely transition to PQC. Visit CISA’s PQC Initiative page for additional resources.

Zyxel GS1900 network switches that received the vendor's earlier fix for an actively exploited flaw are still open to the exploit attackers used, researchers at Binarly found. The exploit lets anyone who can reach a switch's web management interface run commands on it without logging in. Zyxel has released new firmware for 10 GS1900 models that closes the hole. The earlier fix is the 2.90

View CSAF Summary Mendix SAML module contains an authentication bypass vulnerability that could allow an unauthenticated remote attacker to gain unauthorized access by replaying a valid SAML assertion in IdP-initiated authentication flows. Siemens has released new versions for the affected products and recommends to update to the latest versions. The following versions of Siemens Mendix SAML Module are affected: Mendix SAML (Mendix 10 compatible) vers:intdot/<4.2.4 (CVE-2026-89209) Mendix SAML (Mendix 11 compatible) vers:intdot/<4.2.4 (CVE-2026-89209) Mendix SAML (Mendix 9 compatible) vers:intdot/<3.6.29 (CVE-2026-89209) CVSS Vendor Equipment v3 6.8 Siemens Mendix SAML (Mendix 10 compatible) 1 Vulnerability Authentication Bypass by Capture-replay Background Critical Infrastructure Sectors: Critical Manufacturing, Information Technology Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities CVE-2026-89209 Affected versions of the module do not properly protect against SAML assertion replay in IdP-initiated authentication flows. This could allow unauthenticated remote attackers to gain unauthorized access to the application by replaying a valid SAML response.

General Recommendations As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity Additional Resources For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories Terms of Use The use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use. Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
