Idira Endpoint Privilege Manager: Improper Certificate Validation
CVE-2026-45175 is a high-severity improper certificate validation vulnerability in Idira Endpoint Privilege Manager from CyberArk Software, a Palo Alto Networks Company, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 26.5 as the first without the flaw, so updating Idira Endpoint Privilege Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.13% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Idira Endpoint Privilege Manager to 26.5 or a later version.

Official description
Idira Endpoint Privilege Manager Agent versions prior to 26.5 exhibit improper access control within internal agent validation processes. A local attacker could potentially bypass built-in security controls or cryptographic validations. Under specific circumstances, this could allow the attacker to circumvent agent self-defense mechanisms and execute unauthorized operations. CyberArk Security Bulletin: CA26-19

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
