CVE-2026-0649 is a Server-Side Request Forgery (SSRF) vulnerability identified in invoiceninja versions up to 5.12.38. The vulnerability resides in the Migration Import component, specifically within the copy function located in /app/Jobs/Util/Import.php. The issue arises from improper handling of the company_logo argument, which an attacker can manipulate to cause the server to initiate unauthorized HTTP requests to arbitrary destinations. This SSRF flaw allows remote attackers to potentially access internal network resources or services that are otherwise inaccessible externally. The vulnerability requires no user interaction but does require that the attacker has high privileges on the application, indicating that exploitation is limited to authenticated users with elevated rights. The CVSS 4.0 base score is 5.1 (medium severity), reflecting network attack vector, low complexity, no user interaction, and limited impacts on confidentiality, integrity, and availability. The vendor was contacted early but did not respond, and no patches or mitigations have been officially released. While no known exploits are currently observed in the wild, the public disclosure increases the risk of exploitation attempts. The vulnerability could be leveraged to perform reconnaissance on internal networks, access sensitive internal services, or potentially pivot to further attacks within the victim environment. Given invoiceninja’s role in financial and invoicing operations, exploitation could disrupt business processes or leak sensitive financial data.

For European organizations, this SSRF vulnerability poses a risk primarily to confidentiality and integrity by enabling attackers to access internal services and potentially exfiltrate sensitive data or manipulate internal communications. Availability impacts are limited but possible if internal services are disrupted. Organizations using invoiceninja for invoicing and financial management may face operational disruptions or data breaches if exploited. The requirement for high privileges reduces the risk from external unauthenticated attackers but insider threats or compromised accounts could exploit this vulnerability. The public disclosure without vendor response increases the urgency for organizations to implement mitigations independently. Financial institutions and enterprises with complex internal networks are particularly at risk, as SSRF can be used to bypass network segmentation and access protected resources. The impact is heightened in countries with high invoiceninja adoption and critical financial sectors, where disruption or data leakage could have significant economic consequences.

1. Restrict network egress from the invoiceninja application server to only necessary external endpoints, blocking access to internal IP ranges and sensitive services. 2. Implement strict input validation and sanitization on the company_logo parameter to prevent injection of malicious URLs or payloads. 3. Employ web application firewalls (WAFs) with rules to detect and block SSRF patterns targeting the vulnerable endpoint. 4. Monitor outbound HTTP requests from the application server for unusual destinations or volumes indicative of SSRF exploitation attempts. 5. Limit the privileges of users who can access the Migration Import functionality to reduce the attack surface. 6. If possible, isolate the invoiceninja instance in a segmented network zone with minimal access to internal resources. 7. Engage in active threat hunting and log analysis to detect potential exploitation attempts. 8. Follow up with the vendor for patches or updates and apply them promptly once available. 9. Consider alternative invoicing solutions if timely patching is not feasible and risk is unacceptable.
