CVE-2025-15669: Bit Form < 3.1.4 - Admin+ Stored XSS via Conversational Form Progress Label
The Bit Form WordPress plugin before 3.1.4 does not sanitise one of its conversational-form display settings before rendering it on the public-facing form, allowing high-privilege users (such as administrators, who do not hold the unfiltered_html capability on multisite) to store JavaScript that executes in the browser of any visitor who views the form.
Security readout for executives and security teams
Plain-English summary
CVE-2025-15669 affects the Bit Form WordPress plugin before 3.1.4. A highly privileged user can save malicious script in a conversational-form progress label, causing it to run for visitors who view that form. Business risk is limited by the need for admin-level access, but visitor impact is possible on exposed forms.
Executive priority
Prioritize patching on public WordPress sites using Bit Form conversational forms, especially multisite environments. This is not a critical unauthenticated takeover issue, but it can affect site visitors and trust if an admin account is misused or compromised.
Technical view
This is a stored cross-site scripting issue (CWE-79) in a public-facing conversational form display setting. The plugin does not sanitize the progress label before rendering. CVSS is 4.8, vector AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N. The described affected range is Bit Form before 3.1.4.
Likely exposure
WordPress sites running Bit Form below 3.1.4 and using conversational forms are the likely exposure. The attack requires high privileges, such as an administrator without unfiltered_html on multisite, plus a visitor viewing the affected form.
Exploitation context
The source bundle references a WPScan vulnerability entry tagged with exploit information, but it does not establish active exploitation. The CVE is not listed as KEV in the provided data. Treat this as a publicly documented issue, not confirmed in-the-wild exploitation.
Researcher notes
Evidence is limited to the CVE data and WPScan reference in the bundle. The affected metadata appears sparse, with vendor unknown and version data not detailed, while the title and description specify Bit Form before 3.1.4. No KEV status or confirmed active exploitation is provided.
Mitigation direction
Upgrade Bit Form to version 3.1.4 or later.
Restrict plugin administration to trusted users only.
Review conversational-form display settings for unexpected script-like content.
Check vendor and WPScan guidance for any additional remediation details.
Validation and detection
Inventory WordPress sites for Bit Form plugin versions below 3.1.4.
Identify sites using Bit Form conversational forms.
Review the conversational-form progress label setting for unsafe content.
Confirm upgraded sites render the form without executing stored script content.

Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
