Summary

CVE-2024-0590 is a medium-severity CSRF (CWE-352) vulnerability in Microsoft Clarity. Its CVSS base score is 6.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 32% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The Microsoft Clarity plugin for WordPress is affected by a cross-site request forgery vulnerability in all versions through 0.9.3. The flaw arises from missing nonce validation on the edit_clarity_project_id() function, which is tracked as CWE-352 and carries a CVSS 3.1 score of 6.1.

Unauthenticated attackers can exploit the issue by crafting a forged request that changes the configured project identifier and injects arbitrary JavaScript; successful exploitation requires the attacker to lure an administrator into performing an action such as clicking a malicious link.

Public references point to a patched changeset in the WordPress plugin repository and a detailed advisory from Wordfence that identify the fixed code revision, indicating that administrators should update to a version newer than 0.9.3. The associated EPSS score remains flat at 0.2476 with no material increase after disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Access enforcement requires verifying that state-changing requests originate from the authenticated user rather than a forged cross-site source.

Protecting session authenticity prevents attackers from replaying or forging authenticated requests via the victim's browser.
