CVE-2025-30884: Bit Integrations Open Redirect Vulnerability

CVE-2025-30884 Overview

CVE-2025-30884 is an open redirect vulnerability in the Bit Apps Bit Integrations WordPress plugin. The flaw affects all versions of bit-integrations up to and including 2.4.10. Attackers can craft URLs that appear to originate from a trusted WordPress site but redirect victims to attacker-controlled domains. This weakness maps to [CWE-601] URL Redirection to Untrusted Site.

Critical Impact
Attackers can leverage the trusted WordPress domain to conduct phishing campaigns, steal credentials, and deliver malware while bypassing user trust signals.

Technical Details for CVE-2025-30884

Vulnerability Analysis

The Bit Integrations plugin accepts a user-supplied redirect target without validating that the destination belongs to an allowed domain list. An attacker constructs a link pointing to a vulnerable endpoint on the WordPress site with a crafted redirect parameter. When a victim clicks the link, the plugin issues an HTTP redirect to the attacker-supplied URL. The victim's browser follows the redirect to a phishing page or malware host. Because the initial URL displays the trusted WordPress domain, victims are more likely to trust the destination and submit credentials or download payloads. Exploitation requires user interaction, so attackers typically pair this flaw with email or social media lures. The impact is limited to confidentiality since the redirect itself does not modify server-side data or bypass authentication controls.

Root Cause

The plugin fails to sanitize or allow-list the redirect destination parameter before invoking a client-side or server-side redirect. Input validation for URL scheme and host is missing, permitting arbitrary external targets.

Attack Vector

Exploitation occurs over the network with low complexity and no authentication. The attacker distributes a crafted link, and a victim must click it. The vulnerability produces a scope change because the trusted origin transfers browser session context to the attacker-controlled site.

No verified public proof-of-concept code is available. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-30884

Indicators of Compromise

Inbound requests to bit-integrations plugin endpoints containing fully qualified external URLs in redirect parameters.
HTTP 301 or 302 responses from the WordPress site pointing to domains outside the organization's allow list.
Referrer logs showing users arriving at unknown external domains after transiting the WordPress host.

Detection Strategies

Inspect WordPress access logs for requests to plugin routes with query parameters containing http://, https://, or // values pointing to external hosts.
Correlate outbound redirects with newly registered domains or domains flagged by threat intelligence feeds.
Alert on user reports of phishing pages that reference the organization's WordPress domain in the initial URL.

Monitoring Recommendations

Enable verbose logging on the WordPress web server and forward logs to a centralized analytics platform.
Monitor for anomalous spikes in traffic to Bit Integrations endpoints, which may indicate active phishing campaigns.
Track user-agent and geolocation patterns on redirect endpoints to identify automated abuse.

How to Mitigate CVE-2025-30884

Immediate Actions Required

Update the Bit Integrations plugin to a version later than 2.4.10 as soon as a patched release is published by Bit Apps.
Audit WordPress installations to inventory all sites running vulnerable versions of bit-integrations.
Review recent web server logs for suspicious redirect activity that may indicate active exploitation.

Patch Information

Consult the Patchstack WordPress Vulnerability Report for the latest patched version guidance from Bit Apps. Apply the vendor-supplied update through the WordPress plugin manager or WP-CLI.

Workarounds

Deactivate the Bit Integrations plugin until a patched version is available if the functionality is not business-critical.
Deploy a web application firewall rule that blocks requests to plugin endpoints containing external URLs in redirect parameters.
Restrict access to plugin administrative endpoints by IP address where feasible.

bash

# Configuration example: WP-CLI plugin update workflow
wp plugin list --name=bit-integrations --fields=name,version,status
wp plugin update bit-integrations
wp plugin deactivate bit-integrations  # if no patch is yet available
