Desk analysis

SolarWinds released patches for critical remote code execution flaws in Observability Self-Hosted, a self-hosted and hybrid IT monitoring platform. CVE-2026-28324 (CVSS 9.8) is an insufficient integrity check leading to unauthenticated RCE on non-default configurations; CVE-2026-28325 (CVSS 8.8) is a deserialization of untrusted data weakness affecting installations using a specific communication mode. Both impact all versions up to 2026.2.2 and were fixed in version 2026.2.3. Kai Huang from Armadin is credited for reporting both defects. SolarWinds also previously patched CVE-2026-28326 (CVSS 8.8) in Access Rights Manager, caused by a hardcoded static key affecting versions up to 2026.2; that advisory was published on September 17, 2026.

No in-the-wild exploitation has been reported for any of these three flaws. Organizations running Observability Self-Hosted or ARM should upgrade to 2026.2.3 (Observability) and ARM 2026.2.1 (ARM) without delay. The combined CVSS scores and unauthenticated attack surface make these high-priority updates, particularly for environments with non-default or externally exposed configurations.

    SolarWinds Patches Critical RCE Flaws in Observability Self-Hosted

    securityweek.com · 19d ago · September 24th, 2026

    SolarWinds has released patches for two severe vulnerabilities in Observability Self-Hosted that could be exploited for remote code execution (RCE). Observability Self-Hosted is an on-premises and hybrid IT monitoring solution that provides organizations with unified monitoring across environments, configuration management, and control over operational data and security compliance. The first flaw, tracked as CVE-2026-28324 (CVSS score of 9.8), is an insufficient integrity check issue leading to RCE on deployments that run non-default and non-secure configurations. Tracked as CVE-2026-28325 (CVSS score of 8.8), the second bug is described as a deserialization of untrusted data weakness affecting installations configured to use a specific communication mode. Both security defects, SolarWinds says, can be exploited by remote attackers without authentication. The vulnerabilities impact all Observability Self-Hosted versions up to 2026.2.2 and were addressed in version 2026.2.3. SolarWinds credited Kai Huang from Armadin for reporting both flaws. Last week, the company patched another unauthenticated RCE bug reported by the security researcher. Tracked as CVE-2026-28326 (CVSS score of 8.8) and affecting SolarWinds’s Access Rights Manager (ARM), it exists because ARM versions up to 2026.2 contain a hardcoded static key. SolarWinds makes no mention of any of these security defects being exploited in the wild. Additional information is avail

    SolarWinds Observability Flaws Let Unauthenticated Attackers Execute Remote Code

    cyberpress.org · 20d ago · September 23rd, 2026

    SolarWinds said both vulnerabilities affect deployments operating under specific non-default communication or configuration conditions, making configuration reviews as important as applying the available update. An unauthenticated attacker could exploit the weakness to execute code remotely against installations configured in a non-default, non-secure manner. In a deserialization attack, an application processes externally supplied serialized data and reconstructs it into objects. When validation or integrity controls are inadequate, an attacker may manipulate that input to trigger unintended application b
