CVE-2025-62747 identifies a missing authorization vulnerability (CWE-862) in the Aum Watcharapon Featured Image Generator, affecting versions up to 1.3.3. The vulnerability arises from incorrectly configured access control security levels, allowing attackers to bypass authorization checks. This means that unauthorized users can access or modify features or data that should be restricted, potentially manipulating image generation processes or associated metadata. The CVSS 3.1 base score is 5.3, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), integrity impact (I:L), and no availability impact (A:N). The vulnerability does not require authentication or user interaction, making it easier to exploit remotely. Although no known exploits are reported in the wild and no patches are currently available, the risk lies in unauthorized integrity modifications that could affect the trustworthiness of generated images or related content. The vulnerability was reserved in October 2025 and published at the end of 2025, indicating recent discovery. Organizations using this product should assess their exposure and implement compensating controls until an official patch is released.

For European organizations, the primary impact is on the integrity of content generated by the Featured Image Generator. Unauthorized modifications could lead to the generation of misleading or manipulated images, potentially damaging brand reputation or misleading internal and external stakeholders. While confidentiality and availability are not directly affected, the integrity compromise could have downstream effects, such as misinformation or content tampering. Organizations in media, marketing, publishing, and digital content management sectors are particularly at risk. The ease of exploitation without authentication increases the threat level, especially for publicly accessible instances of the product. Lack of patches means organizations must rely on internal controls and monitoring to mitigate risk. The impact is moderate but could escalate if attackers combine this vulnerability with other weaknesses or use it as a foothold for further attacks.

1. Immediately review and tighten access control configurations on all instances of the Featured Image Generator to ensure that unauthorized users cannot access or modify restricted functions. 2. Implement network-level restrictions such as IP whitelisting or VPN access to limit exposure of the application to trusted users only. 3. Monitor logs and audit trails for unusual or unauthorized access attempts related to image generation features. 4. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable endpoints. 5. Until an official patch is released, consider isolating the application in a segmented network environment to reduce potential attack surface. 6. Educate administrators and users about the vulnerability and encourage prompt reporting of anomalies. 7. Regularly check for vendor updates or patches and apply them immediately upon release. 8. Conduct penetration testing focused on access control mechanisms to identify and remediate similar weaknesses proactively.
