CVE-2026-24535 identifies a missing authorization vulnerability in the 'Automatic Featured Images from Videos' plugin developed by webdevstudios, affecting versions up to and including 1.2.7. The vulnerability arises due to incorrectly configured access control security levels, allowing users with some privileges (authenticated users with limited rights) to perform actions that should be restricted. Specifically, the plugin fails to properly verify whether a user is authorized to execute certain functions related to automatic featured image generation from videos. The flaw can be exploited remotely over the network without requiring user interaction, but does require the attacker to have some level of authenticated access (PR:L). The CVSS v3.1 score is 4.3, indicating a medium severity level, with the vector indicating network attack vector, low attack complexity, privileges required, no user interaction, unchanged scope, limited confidentiality impact, and no impact on integrity or availability. No public exploits are known at this time. The vulnerability could allow an attacker to manipulate or trigger plugin functionality in unintended ways, potentially leading to unauthorized content changes or exposure of limited information. Since the plugin is used in WordPress environments, the risk is tied to the presence of this plugin and the privilege level of users on the affected sites.

For European organizations, the impact of CVE-2026-24535 is primarily related to unauthorized access to plugin functionality that could lead to limited confidentiality breaches or unauthorized content modifications. While the vulnerability does not directly compromise system integrity or availability, it could be leveraged by malicious insiders or compromised accounts to manipulate featured images or related media content, potentially damaging brand reputation or misleading users. Organizations with WordPress-based websites that use this plugin, especially media companies, e-commerce platforms, or content-heavy sites, are at risk. The medium severity rating suggests that while the threat is not critical, it should not be ignored, particularly in regulated sectors where unauthorized content changes could have compliance implications. The absence of known exploits reduces immediate risk, but the vulnerability could be targeted in the future. European entities must assess their exposure based on plugin usage and user privilege models.

1. Immediately audit all WordPress installations for the presence of the 'Automatic Featured Images from Videos' plugin and identify versions ≤ 1.2.7. 2. Restrict user privileges to the minimum necessary, ensuring that only trusted users have access to plugin-related functionalities. 3. Monitor and log plugin-related activities to detect any unauthorized attempts to exploit access control weaknesses. 4. Since no patch links are currently available, contact the vendor or monitor official channels for updates and apply patches promptly once released. 5. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. 6. Consider temporarily disabling or uninstalling the plugin if it is not critical to operations until a secure version is available. 7. Educate site administrators about the risks of privilege escalation and the importance of strong authentication controls.
