Redis Enterprise Elevation of Privilege Vulnerability

IdentifiersCVE-2025-59271CWE-285· Improper Authorization

CVE-2025-59271 is a high-severity elevation of privilege vulnerability affecting Microsoft Azure Cache for Redis Enterprise / Redis Enterprise servers used in Azure Redis services. Based on the available public information, the flaw is caused by insufficient authorization checks, resulting in an authorization logic weakness. An authenticated remote user with limited permissions may be able to perform actions intended for more privileged accounts within the service. Publicly available sources do not provide vulnerable function names, affected version details, or detailed exploitation mechanics.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated attacker to escalate privileges within the affected Azure Cache for Redis Enterprise environment. This could enable unauthorized administrative or higher-privileged actions within the service boundary, undermining tenant or role-based access controls. Public sources do not provide more granular impact details beyond privilege escalation.

Mitigation

If you can’t patch tonight, do this now.

Until confirmed remediation guidance is available, reduce exposure by enforcing least-privilege access for all Azure Cache for Redis Enterprise users and service principals, reviewing and minimizing assigned roles, restricting administrative access paths, monitoring for anomalous privileged operations, and auditing authentication and authorization activity related to Redis Enterprise management actions. Public sources do not describe any official vendor workaround beyond patching/service remediation.

Remediation

Patch, then assume compromise.

Apply the vendor-provided security update or service-side fix from Microsoft for CVE-2025-59271 as soon as it is available in your Azure Cache for Redis Enterprise deployment. Because public sources cited here do not include version-specific patch guidance or affected build information, defenders should consult the Microsoft Security Response Center advisory and Azure service update documentation for authoritative remediation details.
