CVE-2025-52802 is a high-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the WordPress plugin 'Import YouTube videos as WP Posts' developed by enguerranws. This vulnerability arises due to improperly configured access control mechanisms within the plugin, allowing unauthorized users to perform actions that should require authorization. Specifically, the flaw enables attackers to exploit the lack of authorization checks when importing YouTube videos as WordPress posts, potentially allowing them to inject or modify content without proper permissions. The vulnerability affects all versions up to 2.1, with no specific version exclusions noted. The CVSS v3.1 score is 7.5, indicating a high severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N) reveals that the attack can be performed remotely over the network without any privileges or user interaction, and while it does not impact confidentiality or availability, it has a high impact on integrity. This means attackers can alter or inject unauthorized content into WordPress sites using this plugin, potentially defacing websites, injecting malicious content, or manipulating posts to spread misinformation or malware. No patches or fixes have been published at the time of this analysis, and no known exploits are currently observed in the wild. The vulnerability is critical for websites relying on this plugin for content automation from YouTube, especially those with public-facing content where integrity is paramount.

For European organizations, this vulnerability poses a significant risk to the integrity of their web content and brand reputation. Organizations using WordPress sites with the 'Import YouTube videos as WP Posts' plugin are at risk of unauthorized content injection or modification, which could lead to misinformation dissemination, defacement, or embedding of malicious links or code. This can erode customer trust, lead to regulatory scrutiny under GDPR if user data or trust is compromised indirectly, and potentially cause financial losses due to downtime or remediation costs. Media companies, educational institutions, and e-commerce platforms that automate content publishing from YouTube are particularly vulnerable. Since the exploit requires no authentication or user interaction, attackers can automate attacks at scale, increasing the likelihood of widespread compromise. The lack of confidentiality impact reduces the risk of data leakage, but the high integrity impact can disrupt business operations and damage organizational credibility.

1. Immediate mitigation involves disabling or uninstalling the 'Import YouTube videos as WP Posts' plugin until an official patch is released. 2. Implement strict web application firewall (WAF) rules to detect and block unauthorized POST or API requests targeting the plugin's import functionality. 3. Restrict access to WordPress administrative endpoints by IP whitelisting or VPN access to reduce exposure. 4. Monitor website content for unauthorized changes or suspicious posts, employing integrity monitoring tools. 5. Employ WordPress security plugins that enforce granular authorization checks and audit plugin behavior. 6. Regularly review and update user roles and permissions to ensure least privilege principles are enforced. 7. Engage with the plugin vendor or community to track patch releases and apply updates promptly. 8. Conduct penetration testing focusing on plugin endpoints to identify potential exploitation paths. These steps go beyond generic advice by focusing on access control hardening, monitoring, and proactive content integrity verification specific to this plugin's functionality.
