CVE-2026-25310 identifies a Server-Side Request Forgery (SSRF) vulnerability in the Alobaidi Extend Link product, affecting versions up to and including 2.0.0. SSRF vulnerabilities occur when an attacker can manipulate a server to send crafted requests to internal or external systems that the server can access but the attacker cannot directly reach. In this case, the Extend Link application improperly validates or sanitizes user-supplied input used to generate server-side requests, allowing attackers to coerce the server into making arbitrary HTTP requests. This can lead to unauthorized access to internal services, bypassing firewalls or network segmentation, and potentially exposing sensitive data or enabling further attacks such as remote code execution or lateral movement within the network. The vulnerability does not require authentication or user interaction, increasing its exploitability. Although no public exploits have been reported, the risk remains significant due to the nature of SSRF attacks. The lack of a CVSS score suggests the need for a severity assessment based on impact and exploitability factors. The vulnerability affects all versions of Extend Link up to 2.0.0, with no patch currently referenced, indicating the importance of monitoring vendor advisories for updates.

For European organizations, the SSRF vulnerability in Extend Link could have serious consequences. Attackers exploiting this flaw can access internal network resources that are otherwise protected, potentially leading to data breaches involving sensitive personal data protected under GDPR. Confidentiality could be compromised if internal APIs, databases, or metadata services are accessed. Integrity risks arise if attackers manipulate internal services or configurations. Availability could also be impacted if attackers use SSRF to trigger denial-of-service conditions on internal systems. Organizations in sectors such as finance, healthcare, and critical infrastructure, which often rely on secure internal communications, are particularly at risk. The vulnerability's ability to be exploited without authentication or user interaction increases the likelihood of automated or remote attacks, raising the threat level for European enterprises using Extend Link. Additionally, the lack of known exploits in the wild currently provides a window for proactive mitigation before widespread exploitation occurs.

1. Monitor Alobaidi's official channels for patches addressing CVE-2026-25310 and apply them promptly once available. 2. Implement strict input validation and sanitization on all user-supplied data that influences server-side requests to prevent malicious payloads. 3. Restrict outbound network traffic from servers running Extend Link to only necessary destinations using firewall rules or network segmentation, minimizing the attack surface for SSRF. 4. Employ web application firewalls (WAFs) with rules designed to detect and block SSRF patterns. 5. Conduct internal security assessments and penetration testing focusing on SSRF vectors within Extend Link deployments. 6. Monitor logs for unusual outbound requests or access patterns indicative of SSRF exploitation attempts. 7. Educate development and operations teams about SSRF risks and secure coding practices to prevent similar vulnerabilities in future releases.
