CVE-2026-25348 identifies a missing authorization vulnerability in the Download Alt Text AI software developed by alttextai, affecting all versions up to and including 1.10.15. The vulnerability stems from improperly configured access control mechanisms, which fail to enforce authorization checks on certain functionalities or endpoints. This misconfiguration allows an attacker to bypass security controls and access or manipulate resources without proper permissions. Although no specific details on the affected components or attack vectors are provided, missing authorization typically enables unauthorized users to perform actions reserved for privileged users, such as downloading sensitive data or altering system behavior. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed, but the risk is significant given that exploitation does not require authentication or user interaction. No known exploits have been reported in the wild, suggesting that the vulnerability is either newly disclosed or not yet weaponized. The issue affects organizations relying on the Download Alt Text AI product for generating or managing alternative text for images, which is critical for accessibility compliance and content management. Attackers exploiting this flaw could compromise the confidentiality and integrity of data processed by the software, potentially leading to unauthorized data disclosure or manipulation. Since the vulnerability is related to access control, availability impact is less likely unless combined with other attack techniques. The vulnerability was published in February 2026, with no patches currently linked, emphasizing the need for immediate attention from users of the affected product.

For European organizations, exploitation of this missing authorization vulnerability could result in unauthorized access to sensitive data or functionality within the Download Alt Text AI application. This may lead to breaches of personal data, especially if the software processes user-generated content or metadata related to accessibility. Organizations subject to strict data protection regulations such as GDPR could face compliance violations and reputational damage. Additionally, manipulation of alt text or related metadata could degrade accessibility compliance, impacting users with disabilities and potentially exposing organizations to legal liabilities. Since the product is likely integrated into digital content workflows, attackers might leverage this vulnerability to insert malicious content or disrupt content integrity. The lack of authentication requirements lowers the barrier for exploitation, increasing the risk of widespread attacks if the vulnerability is publicly disclosed without mitigation. European entities relying on AI-driven accessibility tools in sectors like education, government, and media are particularly at risk due to their dependence on accurate and secure alt text generation.

Organizations should immediately audit their Download Alt Text AI deployments to identify any exposed endpoints or functionalities lacking proper authorization checks. Until an official patch is released, implement compensating controls such as network segmentation, restricting access to the application to trusted users and IP ranges only. Review and harden access control policies within the application configuration, ensuring that all sensitive operations require proper authentication and authorization. Monitor logs for unusual access patterns that may indicate exploitation attempts. Engage with the vendor alttextai to obtain timelines for patches or updates addressing this vulnerability. Consider deploying web application firewalls (WAFs) with custom rules to block unauthorized requests targeting the vulnerable components. Educate development and security teams about secure coding practices related to access control to prevent similar issues in future software versions. Finally, prepare incident response plans to quickly contain and remediate any exploitation events.
