PAM SH Vault: Uncontrolled Resource Consumption

Published Updated By the CyberSecBulletin desk

CVE-2026-45169 is a high-severity uncontrolled resource consumption vulnerability in PAM SH Vault from CyberArk Software, a Palo Alto Networks Company, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 14.0.8, 14.2.7, 14.6.5 as the first without the flaw, so updating PAM SH Vault to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update PAM SH Vault to 14.0.8 or 14.2.7 or 14.6.5 or 15.0.3, whichever matches your release line, or a later version.
  2. Update Idira Privileged Access Manager Vault to 14.0.8 or 14.2.7 or 14.6.5, whichever matches your release line, or a later version.
  3. Read the advisory on docs.cyberark.com for workarounds and exact fixed builds.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Uncontrolled Resource Consumption

The product does not properly control the allocation and maintenance of a limited resource.

How developers prevent this class of flaw

  • Ensure that protocols have specific limits of scale placed on them.
  • Ensure that all failures in resource allocation place the system into a safe posture.
