CVE-2025-67962 is a security vulnerability classified as an SQL Injection flaw in the Broken Link Checker plugin by the AIOSEO Plugin Team, affecting all versions up to 1.2.6. The vulnerability stems from improper neutralization of special characters in SQL commands, which allows attackers to inject malicious SQL code. This can lead to unauthorized access or manipulation of the underlying database, potentially exposing sensitive information or allowing attackers to alter or delete data. The plugin is commonly used in WordPress environments to monitor and manage broken links for SEO purposes. Since the vulnerability does not require authentication or user interaction, it can be exploited remotely by sending crafted requests to the affected plugin endpoints. No CVSS score has been assigned yet, and no public exploits have been reported, but the risk remains significant due to the nature of SQL Injection vulnerabilities. The vulnerability was published on December 16, 2025, and no official patches or updates are currently linked, indicating the need for immediate attention from users of the plugin. The lack of patches means organizations must consider temporary mitigations such as disabling the plugin or implementing web application firewall (WAF) rules to block suspicious inputs. Given the widespread use of WordPress and SEO plugins, this vulnerability could have broad implications if exploited.

For European organizations, exploitation of this SQL Injection vulnerability could lead to severe consequences including unauthorized disclosure of sensitive data, corruption or deletion of critical information, and potential full compromise of the affected web application’s database. This could disrupt business operations, damage reputation, and lead to regulatory penalties under GDPR due to data breaches. Organizations relying on the Broken Link Checker plugin for SEO and website health monitoring may experience degraded service or loss of trust from customers. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within corporate environments. The impact is particularly critical for sectors with stringent data protection requirements such as finance, healthcare, and government institutions in Europe. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits rapidly after public disclosure.

European organizations should immediately inventory their WordPress installations to identify the presence of the Broken Link Checker plugin and its version. Until an official patch is released, it is advisable to disable or uninstall the plugin to eliminate the attack surface. Implementing strict input validation and parameterized queries at the application level can reduce risk if custom development is feasible. Deploying Web Application Firewalls (WAFs) with rules designed to detect and block SQL Injection attempts targeting the plugin’s endpoints is recommended. Monitoring web server logs for unusual or suspicious requests related to the plugin can help detect attempted exploitation. Organizations should also ensure regular backups of their databases and web content to enable rapid recovery in case of compromise. Once a patch becomes available, prompt application of updates is critical. Additionally, raising awareness among IT and security teams about this vulnerability will help maintain vigilance against exploitation attempts.
