Unauthenticated Cross Site Scripting (XSS) in JetFormBuilder <= 3.6.0.1 versions.
AnalysisAI
Unauthenticated reflected/stored cross-site scripting in the JetFormBuilder WordPress plugin versions 3.6.0.1 and earlier allows remote attackers to inject script into pages rendered to victims. Exploitation requires a victim to interact with a crafted link or form (UI:R), and successful payload execution can hijack sessions or perform actions in the victim's browser context. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires (1) a WordPress site running JetFormBuilder version 3.6.0.1 or earlier with a JetFormBuilder-generated form or endpoint reachable to unauthenticated visitors, and (2) victim user interaction - either clicking an attacker-supplied link containing the payload or loading a page where a previously injected payload is rendered (UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed: CVSS 7.1 (High) with AV:N/AC:L/PR:N reflects easy network reachability without credentials, but UI:R means a victim must click or load attacker-controlled content, and C/I/A are all Low rather than High. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a URL or form-submission payload targeting a JetFormBuilder-rendered field on a victim WordPress site and distributes it via email, social media, or a malicious site. When a logged-in administrator or visitor follows the link, the injected JavaScript executes in their browser under the site's origin, enabling session-cookie theft, CSRF actions against wp-admin, or silent redirection. … |
| Remediation | No vendor-released patch identified at time of analysis in the provided data - administrators should monitor the JetFormBuilder changelog and the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/jetformbuilder/vulnerability/wordpress-jetformbuilder-plugin-3-6-0-1-cross-site-scripting-xss-vulnerability) for a release above 3.6.0.1 and upgrade immediately when available. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all WordPress installations running JetFormBuilder 3.6.0.1 or earlier; disable the plugin and assess which pages are affected. …
