Deeper analysis

CVE-2025-30855 is a missing authorization vulnerability, classified under CWE-862, in the WordPress plugin Ads by WPQuads (quick-adsense-reloaded). This issue affects all versions of the plugin from n/a through 2.0.87.1 and stems from exploiting incorrectly configured access control security levels. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N), indicating high severity due to its potential for unauthorized data modification.

Unauthenticated remote attackers can exploit this vulnerability over the network with low attack complexity and no requirement for user interaction. Exploitation enables high integrity impact, allowing attackers to bypass authorization checks and perform actions they should not be permitted to, such as altering plugin configurations or ad placements.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

AC-3 directly enforces approved authorizations for access to system resources, addressing the missing authorization checks that allow unauthenticated attackers to perform privileged actions like altering plugin configurations.

SI-2 Flaw Remediation good match
prevent

SI-2 requires timely remediation of flaws, directly mitigating this CVE by patching the vulnerable WordPress plugin versions up to 2.0.87.1.

AC-6 Least Privilege partial match
prevent

AC-6 applies least privilege to limit the scope and impact of unauthorized actions enabled by the broken access control in the plugin.
