CVE-2025-69299 is a Server-Side Request Forgery (SSRF) vulnerability identified in Laborator Oxygen, a software product used for web and application security testing. The vulnerability affects all versions up to and including 6.0.8. SSRF vulnerabilities occur when an attacker can manipulate a server to send crafted requests to internal or external systems on behalf of the server, bypassing network access controls. In this case, the flaw allows attackers to coerce the Oxygen server into making arbitrary HTTP requests, potentially accessing internal services, cloud metadata endpoints, or other restricted resources that are not directly accessible externally. This can lead to sensitive information disclosure, internal network mapping, or pivoting to other attacks such as remote code execution if combined with other vulnerabilities. The vulnerability was reserved at the end of 2025 and published in early 2026, with no CVSS score assigned yet and no known exploits in the wild. The lack of authentication requirements or user interaction details suggests the attack surface may be broad, depending on how Oxygen is deployed and accessed. The absence of patch links indicates that fixes may not yet be publicly available, emphasizing the need for proactive mitigation strategies.

The impact of CVE-2025-69299 can be significant for organizations using Laborator Oxygen, especially those with sensitive internal networks or cloud environments. Successful exploitation could allow attackers to bypass perimeter defenses, access internal-only services, retrieve sensitive data such as credentials or configuration files, and perform reconnaissance to facilitate further attacks. In cloud environments, SSRF can enable access to metadata services, potentially exposing credentials or tokens that lead to full account compromise. The vulnerability could also be leveraged to attack other internal systems indirectly, increasing the attack surface. For organizations relying on Oxygen for security testing, exploitation could undermine trust in the tool and expose critical infrastructure. Although no exploits are currently known, the potential for damage is high given the nature of SSRF vulnerabilities and the typical deployment contexts of such software.

Organizations should monitor Laborator's official channels for patches addressing CVE-2025-69299 and apply them promptly once available. Until patches are released, implement network-level restrictions to limit the Oxygen server's ability to make outbound HTTP requests, especially to internal IP ranges and sensitive endpoints like cloud metadata services. Employ strict input validation and sanitization on any user-controllable parameters that influence server requests. Use web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block suspicious request patterns indicative of SSRF attempts. Conduct thorough security reviews of Oxygen deployments to ensure minimal exposure and isolate the server within segmented network zones. Additionally, monitor logs for anomalous outbound requests and unusual server behavior. Educate security teams about SSRF risks and incorporate this vulnerability into incident response plans.
