🟠 High | Source: Microsoft Security Response Center A remote code execution vulnerability in Azure Service Bus allows an attacker who already has authorised access to run arbitrary code over a network by exploiting unsafe deserialisation of untrusted data. This is a serious flaw because compromised messaging infrastructure can cascade across dependent services and workloads. Organisations using Azure Service Bus as part of their integration or event-driven architectures should treat this as a priority issue. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in Azure Logic Apps allows an authenticated attacker to access information they should not be able to see by exploiting improper access controls over a network. This is an information disclosure flaw, meaning an attacker with existing access could potentially expose sensitive data processed or stored within Logic Apps workflows. Logic Apps is widely used to integrate services and automate business processes, so exposed data could include credentials, API keys, or business-critical payloads. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in Azure SQL Database allows an unauthenticated attacker to elevate their privileges over a network without requiring any user interaction. The flaw stems from improper authentication handling, meaning an attacker could potentially gain higher-level access to database resources than intended. This is particularly concerning given the widespread use of Azure SQL Database for storing sensitive business and customer data. Security Architect’s Take: Review your Azure SQL Database instances for any unusual access patterns immediately and ensure network-level controls such as firewall rules and private endpoints are restricting exposure to trusted networks only. Monitor Microsoft’s update guide for patch availability and apply any service-side mitigations as soon as they are released. ...

🟠 High | Source: Microsoft Security Response Center A path traversal-style vulnerability (using ‘../../../’ sequences) in Microsoft Entra’s Provisioning Service (SyncFabric) allows an already-authenticated attacker to escalate their privileges over the network. Because Entra Provisioning underpins identity synchronisation between on-premises directories and Azure AD, exploitation could grant an attacker broader control over user accounts and access policies. The requirement for prior authorisation reduces risk slightly, but the blast radius in hybrid identity environments is significant. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in Microsoft Power Apps allows an attacker on a network to gain elevated privileges without proper authorisation. This stems from improper authorisation controls within the platform, meaning an attacker could access resources or perform actions beyond their permitted scope. Power Apps is widely used across enterprises for business application development, making the potential blast radius significant. Security Architect’s Take: Review access controls and audit logs for your Power Apps environments immediately, and apply any Microsoft-issued patches or mitigations without delay. Additionally, enforce least-privilege principles on Power Apps connectors and restrict network-level access to Power Apps environments where possible. ...

🟠 High | Source: Microsoft Security Response Center CVE-2026-62830 is an elevation of privilege vulnerability in Azure SRE Agent, Microsoft’s site reliability engineering tooling for Azure. A flaw in missing authorisation checks means an already-authenticated attacker could abuse the agent over a network to gain higher privileges than intended. If exploited, this could allow an attacker to escalate their access within an Azure environment, potentially compromising resources or data beyond their permitted scope. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in Azure SQL Managed Instance allows an unauthenticated attacker to gain elevated privileges over a network by exploiting improper restrictions on communication channels. This means an attacker could potentially access or control resources beyond their intended permissions without needing prior authentication. The network-based attack vector makes this particularly concerning for organisations with internet-exposed or multi-tenant SQL Managed Instance deployments. Security Architect’s Take: Review network access controls for Azure SQL Managed Instance endpoints immediately, ensuring private endpoints and network security groups are enforced to limit exposure. Monitor Microsoft’s MSRC advisory for a patch or mitigation guidance and apply any available updates as a priority given the unauthenticated, network-exploitable nature of this flaw. ...

🟠 High | Source: Microsoft Security Response Center CVE-2026-62869 is a spoofing vulnerability in Azure Entra ID (formerly Azure Active Directory) caused by insufficient verification of data authenticity. An attacker who already has some level of authorised access could exploit this over a network to impersonate another identity or entity. This is particularly concerning given Entra ID’s role as the central identity provider for Microsoft cloud environments, where a spoofed identity could enable lateral movement or unauthorised resource access. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in Microsoft Teams allows an already-authenticated attacker to gain higher-level privileges than they should have, purely over the network and without requiring physical access. This is concerning because Teams is widely used across enterprise environments, meaning a compromised or malicious insider account could leverage this flaw to escalate access significantly. The blast radius could be substantial in organisations where Teams is integrated with other Microsoft 365 and Azure services. ...

🟠 High | Source: Microsoft Security Response Center A vulnerability in Microsoft Teams allows an attacker on the same network to spoof messages or identities by exploiting improper verification of cryptographic signatures. This means communications that appear to come from a trusted source could in fact originate from a malicious actor. In enterprise environments where Teams is central to business communication, this creates a credible phishing and social engineering vector. Security Architect’s Take: Ensure Microsoft Teams is fully patched to the latest version across all endpoints and verify that auto-update policies are enforced via Intune or your endpoint management platform. Additionally, review any conditional access policies to limit Teams access to managed, compliant devices, reducing exposure in cases where patching lags. ...
