Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated account on the target WordPress site (CVSS PR:L), so the attacker must already hold at least a low-privilege role such as subscriber or contributor - commonly obtainable where open registration is enabled. … 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:H/I:H/A:H, score 8.8) indicates a network-reachable, low-complexity attack requiring only low privileges and no user interaction, with high impact across confidentiality, integrity, and availability - consistent with full site compromise once a foothold account exists. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or obtains a low-privilege account (e.g., subscriber or contributor) on a WordPress site running a vulnerable aBlocks version, then sends a crafted request to the plugin's privilege-assignment functionality to grant their own account administrator-level capabilities. Given AV:N/AC:L/UI:N, this requires no victim interaction and low effort; no public POC has been identified at time of analysis. |
| Remediation | Vendor-released patch: aBlocks 2.9.1 - upgrade the plugin to version 2.9.1 or later, which is the primary and definitive fix per the Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/ablocks/vulnerability/wordpress-ablocks-plugin-2-9-1-privilege-escalation-vulnerability?_s_id=cve). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit all WordPress installations for aBlocks plugin presence and version; identify and review all subscriber and contributor-level accounts with recent activity or suspicious behavior. …
