CVE-2026-45175: Idira Endpoint Privilege Manager Agent Improper Access Control (CVSS 7.8)

Technical summary

CVE-2026-45175 stems from improper access control mechanisms within the Idira Endpoint Privilege Manager Agent's internal validation processes. The agent relies on cryptographic validations and self-defense mechanisms to enforce privilege boundaries; this flaw allows a local attacker with user-level permissions to circumvent those controls. The vulnerability is mapped to CWE-295 (Improper Certificate Validation), suggesting the weakness involves inadequate cryptographic or certificate-based enforcement. Exploitation requires local system access and valid user credentials, but no user interaction is necessary once the attacker is authenticated.

Business impact

Idira Endpoint Privilege Manager is a critical control for managing and monitoring elevated operations across endpoints. Compromise of its validation mechanisms creates a direct path for privilege escalation and unauthorized execution of sensitive commands. Organizations relying on Idira to enforce least-privilege policies, audit elevated operations, or prevent unauthorized access to protected resources face a significant control gap until patching is complete. This is particularly acute in environments where endpoint privilege management is a key security pillar for compliance, incident response, or zero-trust implementations.

Affected systems

Idira Endpoint Privilege Manager Agent versions prior to 26.5 are affected. The agent operates on multiple platforms including Windows, macOS, and Linux, meaning vulnerability scope spans heterogeneous endpoint environments. Any organization running affected versions of the Idira agent on production endpoints requires assessment and remediation. Operating system versions themselves (Windows, macOS, Linux kernel) are listed as affected in the CVE metadata but are not the root cause; they are the deployment platforms.

Exploitability

Exploitation requires local access and valid user credentials on the affected system (AV:L/PR:L in the CVSS vector). This represents a moderate barrier—the attacker cannot exploit remotely, but any authenticated local user can attempt to trigger the flaw. No special tooling, zero-day exploit code, or user interaction is required once the attacker is logged in. The simplicity of the attack path, combined with the high impact (confidentiality, integrity, and availability all affected), makes this a meaningful risk in environments with multiple local users or shared endpoint access.

Remediation

Update Idira Endpoint Privilege Manager Agent to version 26.5 or later. Organizations should prioritize patching across all affected endpoints, starting with systems that handle sensitive operations or operate in high-value network segments. Verify the patch against CyberArk's Security Bulletin CA26-19 for any prerequisites, rollback procedures, or platform-specific guidance. Until patching is complete, enforce compensating controls such as enforcing strong authentication, limiting local user accounts, and monitoring Idira agent logs for suspicious validation errors or self-defense bypass attempts.

Patch guidance

Obtain version 26.5 or later from CyberArk through your existing update channels or directly from their security advisory (CA26-19). Test the patch in a non-production environment first to ensure compatibility with your privilege management policies and workflows. Coordinate patching across your endpoint fleet to minimize operational disruption. Verify successful deployment by confirming agent version numbers and re-running internal validation tests if available. Document the patch baseline for audit and compliance purposes.

Detection guidance

Monitor Idira agent logs for repeated validation failures, failed cryptographic checks, or unexpected self-defense mechanism triggers. Endpoint detection and response (EDR) tools should flag unusual privilege escalation attempts originating from local user accounts, particularly those that succeed despite normal Idira controls. Look for processes spawned by the Idira agent with unexpected elevated privileges or those that bypass normal approval workflows. Review audit logs for operations executed without corresponding privilege management approvals. Test detection rules against known bypass patterns if proof-of-concept code becomes available in threat intelligence feeds.

Why prioritize this

CVE-2026-45175 merits immediate attention due to its HIGH severity rating (CVSS 7.8), the criticality of the affected software (endpoint privilege management), and the direct risk to organizational access controls. The vulnerability does not yet appear on the CISA Known Exploited Vulnerabilities (KEV) list, but the low barrier to exploitation (local access only) and high impact make it likely that threat actors will develop working exploits rapidly. Organizations that depend on Idira for regulatory compliance or zero-trust enforcement cannot afford extended exposure.

Risk score, explained

The CVSS 7.8 HIGH score reflects the combination of local attack complexity, authenticated user requirement (limiting immediate exposure), and severe impact across confidentiality, integrity, and availability. The vulnerability allows a local user to bypass critical security controls—cryptographic validations and self-defense mechanisms—within a privilege management agent. While not remotely exploitable, the consequence of successful exploitation (unauthorized privilege escalation, circumvention of audit controls) is severe. The score appropriately weights the control-plane nature of the affected software: compromise of Idira directly undermines an organization's ability to enforce least privilege and visibility over elevated operations.
