Subscriber Broken Access Control in Advanced Form Integration <= 1.126.12 versions.
AnalysisAI
Broken Access Control in the Advanced Form Integration WordPress plugin (versions ≤ 1.126.12) allows authenticated subscriber-level users to perform privileged actions that should be restricted to administrators, due to missing authorization checks (CWE-862). The flaw carries a CVSS 3.1 score of 6.5 with high integrity impact (I:H), meaning a low-privilege attacker can substantially alter plugin or form integration configurations. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress account at subscriber level or above on the target site running Advanced Form Integration ≤ 1.126.12. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N reflects a network-exploitable flaw requiring only low-privilege authentication, no user interaction, and no special configuration - resulting in high integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free subscriber account on a WordPress site running Advanced Form Integration ≤ 1.126.12 (or uses an already-compromised low-privilege credential), then sends a crafted authenticated HTTP POST request to a plugin AJAX endpoint that lacks capability checks. The missing authorization allows the attacker to overwrite form integration settings - for example, redirecting form submissions to an attacker-controlled third-party webhook - thereby silently harvesting all future user-submitted data including contact details, credentials, or payment information. … |
| Remediation | Update the Advanced Form Integration plugin to a version beyond 1.126.12 once the vendor (Nasir Ahmed) releases a patched build - an exact fixed version has not been independently confirmed from the available data, so monitor the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/advanced-form-integration/vulnerability/wordpress-advanced-form-integration-plugin-1-126-12-broken-access-control-vulnerability and the official WordPress plugin repository for an updated release. … Detailed patch versions, workarounds, and compensating controls in full report. |
