## Key facts

- **Exploitation phase:** Background Noise. Continuous low-level scanning or exploitation attempts are observed, mostly opportunistic and automated.
- **CVSS score:** 7.2
- **Public exploit available:** Yes
- **Affected products:** OneUptime
- **Weaknesses:** CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'))
- **Tags:** web_application, nodejs

## Description

OneUptime is a solution for monitoring and managing online services. Prior to 10.0.21, an unauthenticated path traversal in the /workflow/docs/:componentName endpoint allows reading arbitrary files from the server filesystem. The componentName route parameter is concatenated directly into a file path passed to res.sendFile() in orker/FeatureSet/Workflow/Index.ts with no sanitization or authentication middleware. This vulnerability is fixed in 10.0.21.

## CrowdSec analysis

[CVE-2026-30958](https://euvd.enisa.europa.eu/vulnerability/CVE-2026-30958) is an unauthenticated path traversal vulnerability in OneUptime versions before 10.0.21. Attackers can exploit the `/workflow/docs/:componentName` endpoint to read arbitrary files from the server filesystem, potentially exposing sensitive configuration data, credentials, and application source code. Updating to version 10.0.21 or later addresses the flaw.

CrowdSec has been tracking this vulnerability and its exploits since 23rd of July 2026.

According to CrowdSec data, while opportunistic exploitation dominates, a portion of threat actors trying to exploit CVE-2026-30958 apply basic targeting methods such as port or service detection. This indicates emerging patterns of selective targeting.
CrowdSec network telemetry also shows that exploitation of CVE-2026-30958 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers target the `/workflow/docs/:componentName` endpoint with URL-encoded directory traversal sequences such as `..%2f`, attempting to access arbitrary files like `/etc/passwd` without authentication.
