CVE-2024-12869 is an authentication bypass vulnerability classified under CWE-306 (Missing Authentication for Critical Function) affecting infiniflow/ragflow version 0.12.0. The flaw allows an authenticated user with limited privileges to access the invite lists of other users without proper authorization checks. The invite list contains sensitive personal information such as email addresses and usernames. This improper authentication exposes user data, violating privacy principles and potentially enabling attackers to conduct targeted phishing or spam campaigns. The vulnerability does not permit modification of data or denial of service, limiting its impact to confidentiality breaches. The CVSS v3.0 base score is 4.3 (medium), reflecting the network attack vector, low complexity, and requirement for some privileges but no user interaction. No patches or exploits are currently reported, but the issue poses a risk especially in environments where sensitive user data is stored. Organizations using infiniflow/ragflow should audit access controls and implement stricter authentication mechanisms for sensitive functions.

For European organizations, the primary impact is the unauthorized disclosure of personal data, which can lead to privacy violations under GDPR and other data protection regulations. Exposure of email addresses and usernames can facilitate phishing, spam, and social engineering attacks, increasing the risk of credential compromise and subsequent breaches. Loss of customer or user trust and potential regulatory fines are significant concerns. While the vulnerability does not directly affect system integrity or availability, the confidentiality breach alone can have cascading effects on organizational security posture. Organizations in sectors handling sensitive user data, such as finance, healthcare, or public services, are particularly at risk. The lack of known exploits reduces immediate risk but does not eliminate the need for prompt remediation.

To mitigate CVE-2024-12869, organizations should: 1) Apply any available patches or updates from infiniflow promptly once released. 2) Implement strict authentication and authorization checks on all functions that access user invite lists or other sensitive data. 3) Conduct code reviews and penetration testing focused on access control mechanisms within infiniflow/ragflow deployments. 4) Monitor logs for unusual access patterns to invite lists or user data. 5) Educate users and administrators about phishing risks stemming from leaked contact information. 6) If patches are not yet available, consider restricting access to the affected functionality to trusted users only or disabling the invite list feature temporarily. 7) Ensure compliance with GDPR by documenting the vulnerability and response measures, and notify affected users if data exposure is confirmed. 8) Employ network segmentation and least privilege principles to limit potential lateral movement if an attacker exploits this vulnerability.
