Subscriber Broken Authentication in MWB HubSpot for WooCommerce <= 1.6.7 versions.
AnalysisAI
Broken authentication in MWB HubSpot for WooCommerce versions 1.6.7 and earlier allows subscriber-level authenticated WordPress users to bypass access controls and invoke functionality reserved for higher-privileged roles.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress subscriber-level account on the target site. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 7.1 (High) is driven primarily by High availability impact (A:H) and network accessibility (AV:N) with low attack complexity (AC:L), though the practical severity is tempered by the PR:L requirement - subscriber-level access is a necessary precondition that blocks fully unauthenticated exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker self-registers as a subscriber on a WooCommerce store running MWB HubSpot for WooCommerce 1.6.7 or earlier, then authenticates and issues crafted HTTP requests targeting unguarded plugin AJAX or REST endpoints. Bypassing the intended authentication gate (CWE-288) with no additional complexity, the attacker disrupts HubSpot CRM synchronization or performs limited unauthorized data modifications. … |
| Remediation | No exact patched version was confirmed in the available input data; the CPE wildcard covers all versions through 1.6.7 without specifying a fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
