CVE-2025-24763: CWE-862 Missing Authorization in Pascal Casier bbPress API
Missing Authorization vulnerability in Pascal Casier bbPress API allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects bbPress API: from n/a through 1.0.14.
AI Analysis
Technical Summary
CVE-2025-24763 is a Missing Authorization vulnerability (CWE-862) identified in the Pascal Casier bbPress API, affecting versions up to 1.0.14. This vulnerability arises due to improperly configured access control mechanisms within the API, allowing unauthorized users to access certain API endpoints or functionalities without proper permission checks. Specifically, the issue is that the API does not enforce authorization controls correctly, which means that an attacker can potentially exploit this flaw to perform actions or retrieve data that should be restricted. The vulnerability has a CVSS 3.1 base score of 5.3, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) shows that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality to a limited extent, but does not affect integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because bbPress is a popular forum software integrated with WordPress, widely used for community discussions and user-generated content. An attacker exploiting this vulnerability could gain unauthorized read access to sensitive information exposed via the API, potentially including user data or private forum content, depending on the deployment and configuration. However, since the vulnerability does not allow modification or disruption of service, the impact is limited to confidentiality breaches. The lack of required authentication or user interaction makes exploitation easier, increasing the risk if the vulnerable API is exposed to untrusted networks.
Potential Impact
For European organizations using bbPress API versions up to 1.0.14, this vulnerability could lead to unauthorized disclosure of sensitive information accessible through the API. This is particularly concerning for organizations hosting private forums, customer support communities, or internal collaboration platforms where sensitive discussions or personal data might be shared. Confidentiality breaches could result in exposure of user identities, contact information, or proprietary discussions, potentially violating GDPR requirements for data protection and privacy. Although the vulnerability does not allow data modification or service disruption, the unauthorized data access could undermine trust and lead to reputational damage. Organizations in sectors such as finance, healthcare, education, and government, which often use community forums for stakeholder engagement, are at higher risk. The medium severity rating suggests that while the threat is not critical, it should be addressed promptly to prevent potential data leaks. Since exploitation requires no authentication or user interaction, attackers can automate scanning and exploitation attempts, increasing the threat surface for exposed APIs.
Mitigation Recommendations
European organizations should take the following specific steps to mitigate this vulnerability: 1) Immediately audit all bbPress API endpoints to identify any that lack proper authorization checks, especially those accessible over public networks. 2) Restrict API access using network-level controls such as IP whitelisting, VPNs, or firewall rules to limit exposure to trusted users and systems only. 3) Implement or enforce robust authentication and authorization mechanisms on the API, ensuring that all sensitive endpoints verify user permissions before granting access. 4) Monitor API access logs for unusual or unauthorized access patterns that could indicate exploitation attempts. 5) Stay updated with vendor advisories and apply patches or updates as soon as they become available, even though no patches are currently linked. 6) Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized API requests. 7) Conduct regular security assessments and penetration testing focused on API security to proactively identify and remediate similar issues. 8) Educate development and operations teams about secure API design and the importance of enforcing authorization controls consistently.
