Executive Summary

CVE-2026-100900 is a Server-Side Request Forgery (SSRF) vulnerability in the DevaslanPHP project-management application. It affects versions up to 1.2.4 and v2.0.0-beta1. The flaw is in the Jira import functionality where user-controlled input for the Jira host URL is trusted without proper validation. The application passes the host parameter directly to Guzzle's HTTP client, allowing an attacker to specify arbitrary URLs, including internal IPs or external servers.

Detection Guidance

To detect this SSRF vulnerability in DevaslanPHP project-management, check for unusual outbound HTTP requests from the application server, especially to internal IPs or unexpected external domains. Monitor logs for failed requests to /jira-import or Guzzle HTTP client errors. Review network traffic for connections to cloud metadata endpoints or internal services.

Impact Analysis

An authenticated attacker could exploit this to make the server send HTTP requests to unintended destinations. This could lead to internal network scanning, access to sensitive internal services, or resource exhaustion. The attack requires an authenticated user session but can be triggered via manipulated Livewire component inputs.

Compliance Impact

This SSRF vulnerability could lead to unauthorized access to internal systems or sensitive data, which may violate GDPR's data protection principles or HIPAA's security requirements for protecting health information. Unrestricted server-side requests could expose personal or confidential data, leading to compliance breaches.

Mitigation Strategies

Immediately restrict access to the /jira-import page by implementing proper authorization checks beyond just hiding the menu item. Validate and sanitize the host parameter in the updateJiraProjects function to only allow trusted domains. Implement allowlisting for hostnames and block requests to internal IPs or sensitive endpoints.
