CVE-2025-46382 is a medium-severity vulnerability classified under CWE-200, which pertains to the exposure of sensitive information to unauthorized actors. This vulnerability affects CyberArk's Identity Provider (IDP) product, specifically the latest versions as of the publication date in July 2025. The vulnerability allows an attacker to gain access to sensitive information without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The attack vector is network-based, meaning exploitation can occur remotely over the network. The impact is limited to confidentiality loss, with no direct impact on integrity or availability. There are no known exploits in the wild at the time of publication, and no patches have been released yet. The vulnerability likely results from improper access controls or information disclosure flaws within the IDP component, potentially exposing sensitive authentication or identity-related data that could be leveraged for further attacks or reconnaissance. Given CyberArk IDP's role in identity and access management, such exposure could undermine trust in authentication processes or reveal sensitive configuration or credential information.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of sensitive identity and access management data. CyberArk IDP is often deployed in enterprises to centralize authentication and identity federation, so exposure of sensitive information could facilitate lateral movement, credential theft, or targeted phishing campaigns. While the vulnerability does not directly affect system integrity or availability, the leaked information could be used to craft more sophisticated attacks or bypass security controls. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face compliance risks if sensitive identity data is exposed. The lack of required privileges or user interaction increases the risk of automated scanning and exploitation attempts once a public exploit becomes available. The absence of patches at the time of disclosure necessitates immediate risk assessment and temporary mitigations to protect sensitive identity infrastructure.

1. Immediately conduct an inventory to identify all CyberArk IDP deployments within the organization and assess exposure to external networks. 2. Restrict network access to the IDP service using network segmentation and firewall rules to limit exposure to trusted management networks only. 3. Monitor network traffic and logs for unusual access patterns or attempts to query sensitive information from the IDP. 4. Implement strict access controls and multi-factor authentication for administrative access to the IDP. 5. Engage with CyberArk support to obtain timelines for patches or workarounds and apply them promptly once available. 6. Consider deploying Web Application Firewalls (WAF) or Intrusion Prevention Systems (IPS) with signatures tuned to detect attempts to exploit information disclosure vulnerabilities. 7. Conduct regular security assessments and penetration tests focusing on identity management infrastructure to detect similar issues. 8. Educate security teams about this vulnerability to ensure rapid detection and response to potential exploitation attempts.
