Vulnerability Assessment
| Weakness |
CWE
ASVS 5.0
V8 - Authorization Unnecessary privilege execution
|
| Exploitation Conditions | Exploitation requires the attacker to already be an authorized, low-privileged principal within an Azure Synapse workspace/tenant (CVSS PR:L) - this is not anonymous remote access. Given AV:N/AC:L/UI:N, once such a foothold exists the attack is network-reachable, low-complexity, and needs no victim interaction. The exact over-privileged feature or interface is not detailed in the available description beyond CWE-250 (a component executing with unnecessary privileges); the MSRC advisory should be consulted for the specific affected surface. Limiting factors that reduce realistic risk: the prerequisite of valid pre-existing workspace credentials, SSVC marking the issue 'not automatable' (no reliable mass/automated exploitation), and the fact that Microsoft hosts and patches the service centrally. |
| Impact | Signals are mixed but lean toward 'real-but-not-urgent.' The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, base 8.8) indicates a network-reachable, low-complexity attack requiring some existing privileges and no user interaction, with total impact to the affected scope - consistent with SSVC's 'Technical Impact: total.' However, SSVC also reports 'Exploitation: none' and 'Automatable: no,' and EPSS is only 0.50% (39th percentile), so there is no evidence of active or imminent mass exploitation. This is not in CISA KEV and no POC is referenced. The key tension: CVSS rates this Critical-adjacent (High) on impact, but the requirement for pre-existing authorization (PR:L) plus 'not automatable' means realistic exploitation is constrained to attackers who already hold a foothold in the Synapse workspace/tenant. Because this is a Microsoft-hosted cloud service, much of the remediation burden falls on Microsoft's server-side fix rather than customer action, lowering the operational urgency for most defenders. |
| Exploit ScenarioDerived | An attacker who already holds a low-privileged account in an Azure Synapse workspace (for example a data engineer or pipeline user) sends crafted requests to an over-privileged Synapse component, causing it to perform actions under elevated privileges and granting the attacker control over data, pipelines, or configurations they should not be able to access. No user interaction or social engineering is required, but the attacker must first possess valid limited credentials in the tenant. No public POC is referenced at time of analysis. |

Alert meAnalysisAIv3 – Jun 29, 2026
Privilege escalation in Microsoft Azure Synapse (the cloud analytics service) allows an already-authorized, low-privileged attacker to elevate their privileges over the network, gaining high confidentiality, integrity, and availability impact (CVSS 8.8). The root cause is a component executing with unnecessary privileges (CWE-250), letting a tenant or workspace user with limited rights break out to a higher trust level. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.50%), with CISA SSVC marking exploitation status as 'none.'
Earlier versions of this analysis (2)
Privilege escalation in Microsoft Azure Synapse Analytics allows an authenticated, low-privileged attacker to elevate privileges across the network because a component executes with unnecessary privileges (CWE-250). With a CVSS 3.1 base score of 8.8 and total impact to confidentiality, integrity, and availability, an attacker who already holds limited access to the service can gain broader control. There is no public exploit identified at time of analysis, and SSVC currently records exploitation as none, but a vendor patch is available.
Privilege escalation in Microsoft Azure Synapse allows an authenticated low-privileged attacker to elevate privileges across a scope boundary over the network, gaining high-impact control over confidentiality, integrity, and availability. The flaw stems from execution with unnecessary privileges (CWE-250), and with a CVSS 9.9 and scope change, a successful exploit affects components beyond the initially vulnerable one. No public exploit identified at time of analysis.
RemediationAI
Patch available per vendor advisory: Microsoft reports a fix is available, and because Azure Synapse is a Microsoft-managed cloud service the correction is typically deployed server-side by Microsoft rather than installed by customers - review the MSRC advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-48584 to confirm whether any customer-side action (e.g., updating self-hosted integration runtimes, Spark/SQL pool runtime versions, or workspace configurations) is required for full mitigation. As compensating controls, apply least-privilege rigorously to Synapse workspace roles and managed identities (restrict Synapse Administrator/Contributor assignments and audit RBAC), enforce Azure Entra Conditional Access and just-in-time/PIM elevation for privileged Synapse roles to shrink the pool of low-privileged accounts that could trigger the flaw, and restrict workspace network exposure via managed virtual networks, private endpoints, and IP firewall rules to limit which authorized identities can reach the service (trade-off: tightening network and RBAC scope can disrupt legitimate pipelines and integration runtime connectivity, so stage changes carefully).

Technical ContextAI · show details
Azure Synapse Analytics is Microsoft's cloud-based enterprise data warehousing and big-data analytics platform, combining SQL pools, Spark pools, data integration pipelines, and serverless query capabilities. The CPE 'cpe:2.3:a:microsoft:azure_synapse:-' confirms the affected component is the Azure Synapse service itself (a hosted SaaS/PaaS offering rather than installable on-premise software). The root cause class is CWE-250 (Execution with Unnecessary Privileges): a process, managed identity, integration runtime, or service component runs at a higher privilege level than its function requires, so an authorized but lower-privileged actor can leverage that over-privileged execution context to perform operations they should not be entitled to.
