CVE-2026-22643 is a vulnerability classified under CWE-20 (Improper Input Validation) found in the Incoming Goods Suite by SICK AG, which integrates Grafana dashboards for monitoring. The issue arises when an attacker inputs an excessively long dashboard title or panel name, which causes Chromium-based browsers to become unresponsive. This is due to Grafana's failure to properly validate input lengths before rendering, leading to resource exhaustion or browser crashes. The vulnerability affects Grafana versions before 11.6.2 and was fixed in version 11.6.2 and later. The CVSS v3.1 score is 8.3, indicating high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality and integrity (C:H, I:H) with low availability impact (A:L). Exploitation could allow attackers to disrupt monitoring capabilities, potentially exposing sensitive operational data or causing denial of service conditions at the browser level. While no exploits are currently known in the wild, the vulnerability poses a significant risk to organizations relying on SICK AG's Incoming Goods Suite for logistics and industrial monitoring. The improper input validation reflects a failure to sanitize or limit input lengths, a common vector for denial of service or information disclosure attacks in web applications.

For European organizations, especially those in manufacturing, logistics, and supply chain sectors using SICK AG's Incoming Goods Suite, this vulnerability could disrupt critical monitoring dashboards, leading to operational delays and potential data exposure. The high confidentiality and integrity impact means attackers might manipulate dashboard data or gain insights into sensitive operational metrics. The denial of service effect on Chromium browsers can hinder real-time decision-making and incident response. Given the reliance on Grafana for visualization, this could cascade into broader operational inefficiencies. The low availability impact suggests the system remains largely functional but with impaired monitoring capabilities. Industries with stringent compliance requirements (e.g., automotive, pharmaceuticals) could face regulatory scrutiny if data integrity is compromised. The absence of known exploits reduces immediate risk but does not preclude targeted attacks, especially in geopolitically sensitive regions or critical infrastructure sectors.

Organizations should immediately upgrade Grafana instances embedded within the Incoming Goods Suite to version 11.6.2 or later to remediate the vulnerability. Implement strict input validation and length restrictions on dashboard titles and panel names at the application level to prevent malformed inputs. Employ web application firewalls (WAFs) with rules to detect and block unusually long input parameters targeting Grafana endpoints. Monitor browser performance and logs for signs of unresponsiveness or crashes linked to dashboard rendering. Conduct regular security assessments and penetration tests focusing on input validation weaknesses in monitoring tools. Educate administrators and users about the risks of accepting untrusted input in dashboard configurations. Where possible, restrict access to Grafana dashboards to trusted networks and authenticated users with minimal privileges. Maintain up-to-date backups of dashboard configurations to enable rapid recovery if exploitation occurs.
