CVE-2026-22487 identifies a Missing Authorization vulnerability classified under CWE-862 in the baqend Speed Kit product, affecting versions up to 2.0.2. This vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges to perform unauthorized actions or modify data beyond their intended permissions. The vulnerability does not expose confidential information nor does it cause service disruption but compromises data integrity by permitting unauthorized changes. The CVSS 3.1 base score is 4.3 (medium), reflecting that exploitation requires network access and low privileges but no user interaction, and the scope remains unchanged. The issue stems from a failure to enforce proper authorization checks on certain API endpoints or functionalities within Speed Kit, which is a web performance optimization tool used to accelerate website loading times by caching and optimizing content delivery. Although no public exploits are known, the vulnerability could be leveraged by attackers who have some level of access to the network or application environment to escalate their privileges or manipulate data. The lack of a patch link suggests that a fix may be pending or that users must implement configuration changes to mitigate the risk. Given that Speed Kit is used primarily in web environments, the attack surface includes web-facing applications relying on baqend’s optimization services. Organizations should audit their Speed Kit deployments for proper access control enforcement and monitor for suspicious activities indicative of unauthorized access attempts.

For European organizations, this vulnerability poses a risk primarily to the integrity of web applications using baqend Speed Kit. Unauthorized modification of data or application state could lead to defacement, manipulation of business logic, or injection of malicious content, potentially damaging brand reputation and customer trust. While confidentiality and availability are not directly impacted, integrity violations can have downstream effects such as incorrect transaction processing or misleading information presented to users. Industries with high reliance on web performance optimization, such as e-commerce, media, and online services, may face increased risk. The medium severity rating indicates that while the threat is not critical, it should not be ignored, especially in environments where attackers can gain low-level access. European organizations must consider compliance implications, as unauthorized data manipulation could violate data protection regulations if it leads to inaccurate personal data processing. The absence of known exploits reduces immediate risk but does not preclude targeted attacks, particularly in high-value sectors.

To mitigate CVE-2026-22487, European organizations should first verify the version of baqend Speed Kit in use and plan for an upgrade once an official patch is released. In the interim, conduct a thorough review of access control configurations within Speed Kit deployments, ensuring that all API endpoints and functionalities enforce strict authorization checks aligned with the principle of least privilege. Implement network segmentation to limit access to Speed Kit management interfaces and restrict access to trusted users only. Enable detailed logging and monitoring of access attempts to detect anomalous behavior indicative of exploitation attempts. Employ Web Application Firewalls (WAFs) with custom rules to block unauthorized requests targeting Speed Kit endpoints. Additionally, perform regular security assessments and penetration testing focused on access control mechanisms. Engage with baqend support or community channels to stay informed about patch releases and recommended configuration best practices. Finally, incorporate Speed Kit security posture into broader vulnerability management and incident response plans to ensure timely detection and remediation.
