1) Improper access control (CVE-ID: N/A)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote user to escalate privileges within the application.
The vulnerability exists due to a logic error that allowed using case-sensitive URLs in REST API calls. A remote low-privileged user (e.g. with subscriber privilege) can request any protected REST API endpoint by changing a single character to uppercase in the URL.
2) SQL injection (CVE-ID: N/A)
CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote user to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data in the "/wp-json/aioseo/v1/objects" REST API. A remote user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
