CVE-2026-25010 identifies a Missing Authorization vulnerability in the ILLID Share This Image plugin, a tool used to facilitate image sharing on websites. The vulnerability stems from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from performing certain actions within the plugin. This misconfiguration can allow attackers to bypass authorization checks, potentially enabling them to share, modify, or access images without proper permissions. The affected versions include all releases up to and including version 2.09. Although no exploits have been reported in the wild, the nature of the vulnerability—missing authorization—means that exploitation could be straightforward, especially if the plugin is publicly accessible. The vulnerability impacts the confidentiality and integrity of data managed by the plugin, as unauthorized users could gain access to sensitive images or manipulate content. Since no authentication is required to exploit this flaw, the attack surface is broad. The lack of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details suggest a significant risk. No patches or mitigation links are currently available, emphasizing the need for immediate attention from users of the plugin. Organizations should audit their use of the plugin, restrict access where possible, and prepare to apply vendor patches once released.

For European organizations, the impact of CVE-2026-25010 could be substantial, particularly for entities relying on the ILLID Share This Image plugin for managing and sharing images on their websites or internal platforms. Unauthorized access could lead to exposure of sensitive or proprietary images, damaging confidentiality and potentially leading to reputational harm. Integrity could be compromised if attackers modify or replace images, which might affect brand trust or lead to misinformation. Availability impact is less direct but could arise if attackers exploit the vulnerability to disrupt image sharing functionality. Sectors such as media, marketing, e-commerce, and any organization with a public-facing web presence using this plugin are at heightened risk. The absence of authentication requirements for exploitation increases the likelihood of automated attacks or mass scanning by threat actors. European GDPR regulations also heighten the consequences of unauthorized data exposure, potentially resulting in legal and financial penalties. Organizations must therefore prioritize identifying the use of this plugin and implementing controls to mitigate risk.

1. Immediately inventory all web assets to identify installations of the ILLID Share This Image plugin, particularly versions up to 2.09. 2. Restrict access to the plugin’s functionalities by implementing web application firewalls (WAFs) with custom rules to block unauthorized requests targeting image sharing endpoints. 3. Review and tighten access control configurations within the plugin settings to ensure that only authorized users can perform sensitive actions. 4. Monitor web server and application logs for unusual or unauthorized access patterns related to image sharing features. 5. Engage with the vendor (ILLID) to obtain patches or updates addressing this vulnerability as soon as they become available and apply them promptly. 6. If patching is delayed, consider disabling or removing the plugin temporarily to eliminate the attack surface. 7. Educate web administrators and developers about the risks of missing authorization vulnerabilities and the importance of secure configuration. 8. Implement network segmentation and least privilege principles to limit the impact of any potential exploitation. 9. Conduct penetration testing focused on access control mechanisms to proactively identify similar weaknesses.
