MITRE ATT&CK
1 technique across 1 tactic: Initial Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the target site to run Crocoblock JetFormBuilder at or below version 3.6.7.1 and to expose a path where script-related HTML tags submitted through the plugin are stored or reflected without neutralization. The available sources do not name the exact form field, endpoint, or configuration that triggers the injection, nor whether contributor/author-level authentication is needed, so the precise prerequisite cannot be confirmed from the provided data. Realistic limiting factors for XSS of this type: a victim typically must view the injected content for the script to fire (victim interaction), and impact is confined to the browser session of whoever renders the payload. The input vector's claim of no user interaction (UI:N) is inconsistent with typical XSS and should be verified against the Patchstack advisory. |
| Impact | This is a moderate-severity cross-site scripting / content-injection flaw (CWE-80, Basic XSS) in the JetFormBuilder WordPress plugin, scored CVSS 5.3. The supplied vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) indicates a network-reachable, low-complexity issue, but it is internally questionable for an XSS bug: it claims no user interaction (UI:N), no scope change (S:U), and only a confidentiality impact (C:L) with no integrity impact (I:N), whereas script injection typically requires a victim to render the payload (UI:R), crosses a security boundary into the victim's browser (S:C), and primarily harms integrity (I:L). Treat the input vector as approximate. No EPSS probability was provided, the CVE is not in CISA KEV, and no working exploit was supplied - only a Patchstack advisory reference, so there is no public exploit identified at time of analysis. The vuln.today decision label is 'this_month', consistent with a real but non-emergency issue: a widely used plugin with a disclosed XSS, but no evidence of active exploitation or mass automation. Net: a genuine patch-this-month item for WordPress operators running JetFormBuilder, not a drop-everything emergency. |
| Exploit ScenarioDerived | An attacker injects script-bearing content through JetFormBuilder (for example via a form field or form-rendered content that is not properly neutralized); when a site user or administrator views the affected page or submission, the attacker's script executes in their browser. No working exploit code was provided - only a Patchstack advisory reference - and the exact injection point and trigger are not described in the available sources. |

Alert meAnalysisAIv1 – Oct 30, 2026
Cross-site scripting (CWE-80, basic XSS) in Crocoblock JetFormBuilder through 3.6.7.1 allows a remote attacker to inject script-related HTML into plugin-handled form content, which executes in the browser of a user who views the crafted page. The assessed CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N (CVSS 5.3), so victim interaction is required and impact is limited to the browser session; the vendor advisory is a Patchstack entry. No CISA KEV listing or public exploit code is identified in the supplied data; the precise form field or endpoint is not described in the available sources.
RemediationAI
The supplied data does not list a fixed JetFormBuilder version, so no vendor-released patch version can be cited at time of analysis; check the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/jetformbuilder/vulnerability/wordpress-jetformbuilder-plugin-3-6-7-1-content-injection-vulnerability?_s_id=cve) for the current patched release. Until a patch is confirmed, reduce exposure by disabling JetFormBuilder forms or fields that render untrusted submitted content, or by restricting form submission and editing privileges to trusted users; disabling the affected form path can break legitimate workflows, and restricting privileges may disrupt contributor or author workflows. The supplied evidence does not describe additional vendor-specific mitigations or confirm that these compensating controls fully eliminate the issue.

Technical ContextAI · show details
JetFormBuilder is a WordPress form-builder plugin; the affected package is identified by CPE cpe:2.3:a:crocoblock:jetformbuilder:*:*:*:*:*:*:*:* through version 3.6.7.1. CWE-80 describes improper neutralization of script-related HTML tags, the basic XSS class where user-supplied markup reaches a rendered page without sufficient encoding or filtering. The independent assessment notes that exploitation requires a path where script-related HTML submitted through the plugin is stored or reflected without neutralization, but the available sources do not name the exact form field, endpoint, or configuration that triggers the injection. The assessed vector is AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N, indicating network exploitation with victim interaction and scope change; confidentiality and integrity impact is low and availability impact is none.
