CVE-2026-39697

Vulnerability

Overview CVE-2026-39697 is a missing authorization vulnerability in the MAIO – The new AI GEO / SEO tool WordPress plugin, affecting all versions up to and including 6.2.8. The plugin fails to properly enforce access controls on certain functions, allowing attackers to exploit incorrectly configured security levels [1].

Exploitation

Details The vulnerability can be exploited without authentication or by users with low privileges. Attackers can send crafted requests to execute functions that should require higher privilege levels, such as administrative actions. This issue is particularly dangerous as it is commonly used in mass-exploit campaigns targeting thousands of websites simultaneously [1].

Impact

Successful exploitation grants attackers the ability to perform unauthorized actions, potentially compromising site integrity and data. The CVSS v3 score of 5.3 reflects the medium severity, though the ease of exploitation and widespread use in automated attacks elevate the practical risk [1].

Mitigation

Users are strongly advised to update the plugin to a version newer than 6.2.8 immediately. If updating is not possible, contacting the hosting provider or a web developer for assistance is recommended to apply workarounds or restrict access to the plugin's functions [1].
