Server: Missing Release of Resource after Effective Lifetime

Published Updated By the CyberSecBulletin desk

CVE-2026-119636 is a high-severity missing release of resource after effective lifetime vulnerability in Server from Devolutions, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 2026.2.23.0 as the first without the flaw, so updating Server to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% 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

Official description

Improper release of expired privileged access checkouts in the PAM scheduled check-in task in Devolutions Server 2025.3.2.0 through 2026.2.22.0 allows an authenticated user with checkout rights on a PAM account to retain access to that account on the target system after the checkout expires via a backlog of 21 or more newer active checkouts that prevents the expired checkout from being checked in and its password from being rotated.

The underlying weakness: Missing Release of Resource after Effective Lifetime

The product does not release a resource after its effective lifetime has ended, i.e., after the resource is no longer needed.

How developers prevent this class of flaw

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
  • It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free resources in a function. If you allocate resources that you intend to free upon completion of the function, you must be sure to free the resources at all exit points for that function including error conditions.
