CVE-2026-49064: Stiofan GetPaid Sensitive Data Exposure Vulnerability

Technical summary

CVE-2026-49064 is classified as an Insertion of Sensitive Information Into Sent Data vulnerability (CWE-201) in Stiofan GetPaid. The application fails to properly sanitize or restrict sensitive data before it is transmitted, allowing attackers on the network to passively observe and extract confidential information. The network-accessible nature of the vulnerability (CVSS vector AV:N) and the absence of authentication requirements (PR:N) mean that any remote actor can exploit this condition without specialized access or social engineering.

Business impact

This vulnerability poses a significant confidentiality risk. Depending on what sensitive data GetPaid transmits—such as API keys, tokens, personally identifiable information, or financial details—attackers could gain unauthorized access to downstream systems or customer data. For organizations using GetPaid in payment processing, the exposure of transaction-related information could lead to regulatory compliance violations (PCI-DSS, GDPR, etc.), reputational harm, and potential financial liability. The lack of authentication requirements amplifies the blast radius, as any Internet-connected instance is at risk.

Affected systems

Stiofan GetPaid versions from the earliest tracked version through 2.8.49 are vulnerable. Organizations running GetPaid should determine which version is deployed in their environment and cross-reference against the affected range. Verify the exact version by checking the application's settings, configuration files, or vendor documentation.

Exploitability

This vulnerability has a CVSS score of 7.5 (HIGH) with a network attack vector, low attack complexity, and no authentication or user interaction required. These characteristics indicate the vulnerability is straightforward to exploit for a remote attacker with basic network access. The absence of active exploitation in the wild (as indicated by KEV status: false) does not diminish the technical exploitability; it reflects current threat landscape data at the time of publication.

Remediation

Organizations must upgrade Stiofan GetPaid to a patched version released after 2.8.49. Verify the patch version and release date against Stiofan's official security advisory or vendor portal before deployment. Until patching is complete, consider network-level segmentation to limit remote access to GetPaid instances, and monitor outgoing traffic for signs of sensitive data leakage.

Patch guidance

Check Stiofan's official security advisories and release notes for the first version after 2.8.49 that addresses CVE-2026-49064. Apply the patch in a controlled manner: test in a staging environment, verify the patch does not break dependent integrations or workflows, and schedule deployment during an appropriate maintenance window. Confirm the vulnerability is resolved by re-running vulnerability scans post-patch.

Detection guidance

Monitor network traffic originating from GetPaid instances for patterns of sensitive data transmission (e.g., API keys, tokens, credentials in cleartext). Implement data loss prevention (DLP) rules to flag outbound traffic containing high-entropy strings or known secret patterns. Additionally, review GetPaid logs and access patterns to identify any suspicious remote queries or unusual data retrieval patterns that may indicate exploitation attempts.

Why prioritize this

This is a HIGH-severity vulnerability requiring urgent remediation. The combination of network accessibility, lack of authentication barriers, and high-confidence information disclosure makes it an attractive target for reconnaissance and lateral movement. Patch immediately, especially if GetPaid handles payment data, customer information, or integration credentials.

Risk score, explained

The CVSS 3.1 score of 7.5 reflects a high-impact confidentiality breach (C:H) via a low-friction attack surface (AV:N, AC:L, PR:N, UI:N). The confidentiality impact is rated as high because sensitive information is directly exposed to attackers; integrity and availability are unaffected. The network attack vector and absence of prerequisites make this vulnerability relatively easy to exploit at scale.
