Lifecycle Timeline
2DescriptionNVD
The Breakdance plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fields' parameter in versions up to, and including, 2.7.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AnalysisAI
Stored cross-site scripting in the Breakdance WordPress page-builder plugin (versions through 2.7.1) lets unauthenticated attackers inject persistent JavaScript through the 'fields' parameter, which then runs in the browser of any user who views the affected page. The flaw carries a CVSS 3.1 score of 7.2, elevated by a scope change (S:C) because the payload executes in visitors' browser sessions rather than the server context. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the ability to reach the Breakdance 'fields' parameter with attacker-controlled input on a site running version 2.7.1 or earlier; per the CVSS vector (PR:N/UI:N) and the description, injection needs no authentication and no user interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N indicates network-reachable, low-complexity, unauthenticated exploitation requiring no user interaction to inject - a genuinely low bar. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker submits a crafted request setting the 'fields' parameter to a malicious script payload, which Breakdance stores without sanitization. When a site administrator or visitor later loads the injected page, the script executes in their browser - enabling session/cookie theft, admin-action forgery, or redirection. … |
| Remediation | Vendor-released patch: 2.7.2 - upgrade the Breakdance plugin to version 2.7.2 or later, per the vendor security update at https://breakdance.com/breakdance-2-7-2-security-update/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, perform asset discovery to identify all WordPress installations using Breakdance version 2.7.1 or earlier; immediately quarantine any pages suspected of compromise from public access. …
