🟠 High | Source: Microsoft Security Response Center CVE-2026-39828 is a vulnerability in the golang.org/x/crypto/ssh package that allows an attacker to bypass certificate-based restrictions in SSH connections. This could permit unauthorised access to systems that rely on SSH certificate validation as a security control. Services and applications built on Go that use this library for SSH communication — including Azure-hosted workloads — may be affected. Architect’s Take: Audit any Go-based services deployed in your Azure environment that use golang.org/x/crypto/ssh for SSH connectivity, and update to the patched version of the library as soon as it is available. Pay particular attention to internal tooling, CI/CD pipelines, and infrastructure automation that may authenticate via SSH certificates. ...

🟡 Medium | Source: Microsoft Security Response Center A buffer over-read vulnerability in Postfix mail transfer agent (versions before 3.8.16, 3.9.10, and 3.10.9) can cause the process to crash when it encounters a malformed enhanced status code missing text after the third numeric segment. This is a denial-of-service risk affecting any system running a vulnerable Postfix version, including those used within Azure-hosted infrastructure. While the vulnerability does not appear to allow remote code execution, an attacker able to deliver a crafted response could disrupt mail delivery services. ...

🟠 High | Source: Microsoft Security Response Center CVE-2026-41140 is a path traversal vulnerability in Poetry, a Python dependency management tool, affecting Python versions 3.10.0–3.10.12 and 3.11.0–3.11.4. The flaw occurs during tar archive extraction, potentially allowing a malicious package to write files outside the intended directory. This could lead to arbitrary file overwrite or code execution on systems that process untrusted Python packages. Architect’s Take: Audit any Azure-hosted pipelines or build environments using Poetry with the affected Python versions and upgrade to patched releases immediately. Pay particular attention to CI/CD systems that install dependencies from external or untrusted sources, as these represent the highest-risk attack surface. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in OpenSSH versions before 10.3 (CVE-2026-35414) means the authorised_keys principals option is not handled correctly in certain edge cases where a principals list is combined with a Certificate Authority that uses comma characters in specific ways. This could allow unintended principals to authenticate, potentially granting unauthorised SSH access to affected systems. The issue is particularly relevant to cloud environments where certificate-based SSH authentication is used at scale. ...

🟢 Low | Source: Microsoft Security Response Center CVE-2025-1149 is a memory leak vulnerability in the GNU Binutils linker tool (ld), specifically within the xstrdup function in xmalloc.c. While memory leaks can cause service instability or denial of service, this issue has been flagged by Microsoft in the context of Azure, suggesting relevance to workloads or toolchains running on Azure infrastructure. The practical security impact is generally low unless an attacker can trigger repeated allocations to exhaust memory resources. ...

🟠 High | Source: The Register — Security Passwords were found stored in plaintext within Active Directory user and computer description fields, making them trivially accessible to any authenticated user on the network. Because AD description fields are readable by all domain users by default, a low-privilege attacker or compromised account could harvest credentials at scale with a simple LDAP query. This represents a significant credential exposure risk in any hybrid or cloud-connected environment where AD is the identity backbone. ...

🟠 High | Source: The Hacker News A critical remote code execution vulnerability (CVE-2026-23479) in Redis, introduced in version 7.2.0 over two years ago, has been patched following discovery by an autonomous AI-powered bug-hunting tool. The flaw is a use-after-free bug in Redis’s blocking-client handling code, allowing any authenticated user to execute arbitrary operating system commands on the host server. This is significant because Redis is widely deployed across cloud environments as a caching and data store layer, meaning exposure could lead to full host compromise. ...

🔴 Critical | Source: The Hacker News A debug flag accidentally left enabled in production builds of multiple Microsoft 365 Android apps disabled a security check that restricts account token sharing to trusted Microsoft applications. As a result, any app installed on the same Android device could silently request and receive the signed-in user’s authentication token, granting full access to email, files, calendar, and the ability to send messages on their behalf. No user interaction, credentials, or elevated permissions were required to exploit this. ...

🔴 Critical | Source: The Hacker News A debug flag accidentally left enabled in production builds of multiple Microsoft 365 Android apps disabled the trust check that normally restricts account-token sharing to authorised Microsoft applications. As a result, any app installed on the same Android device could silently request and receive a valid authentication token, granting full access to the victim’s email, files, calendar, and messaging without any user interaction or additional permissions. The flaw affects any user running a vulnerable Microsoft 365 Android app while also having a malicious or compromised app on the same device. ...

🟠 High | Source: The Register — Security A security researcher has publicly leaked Microsoft exploit code in protest at how the company handles vulnerability disclosures, following a similar incident by a researcher known as Nightmare Eclipse. The move bypasses responsible disclosure norms, meaning working exploits are now publicly available before Microsoft has necessarily issued patches. This significantly raises the risk for organisations running unpatched Microsoft and Azure environments. Architect’s Take: Review your Microsoft and Azure patch status immediately and prioritise any outstanding security updates — publicly available exploit code dramatically shortens the window between disclosure and active exploitation. Ensure your vulnerability management process includes alerting on zero-day and pre-patch public exploit releases, not just CVE publication. ...
