CVE-2026-32824: dataCycle-CORE CSRF Vulnerability

CVE-2026-32824 Overview

CVE-2026-32824 is an open redirect vulnerability in dataCycle-CORE, the module handling core processing and framework rules within the dataCycle data management system. Versions up to and including 25.07.3 accept attacker-controlled forwardToUrl and redirectUrl parameters during password reset and confirmation flows without host allowlisting. A low-privileged authenticated API user can weaponize these parameters to send password reset or confirmation links containing valid tokens to victims, with the links pointing to attacker-controlled domains. The flaw is tracked as CWE-601: URL Redirection to Untrusted Site and is fixed in version 26.06.08.

Critical Impact
Authenticated attackers can hijack password reset tokens, phish users through trusted email channels, and redirect victims from legitimate authentication flows into attacker-controlled domains.

Affected Products

dataCycle-CORE versions up to and including 25.07.3

Technical Details for CVE-2026-32824

Vulnerability Analysis

The vulnerability resides in the password reset and confirmation email workflows exposed through the dataCycle API. A low-privileged authenticated user can submit forwardToUrl and redirectUrl values when triggering these flows. The application embeds those values directly into the outgoing email links and post-reset browser redirect without validating them against an allowlist of trusted hosts.

This produces two abuse paths. First, password reset or confirmation links can be delivered to a victim from the trusted application email address, but the embedded link points to an attacker-controlled host with the valid token already attached. Second, after a legitimate password reset completes in the browser, the user is redirected to an attacker-supplied redirectUrl. Both paths enable phishing, token capture, and account takeover through confirmation hijacking.

Root Cause

The root cause is missing host allowlisting on user-supplied URL parameters embedded into privileged workflow emails. The application trusts input from authenticated API users without applying redirect validation, violating standard [CWE-601] guidance for URL redirection sinks.

Attack Vector

Exploitation requires network access to the dataCycle API and low-privileged authenticated credentials. The attacker calls the password reset or confirmation trigger endpoint and supplies forwardToUrl or redirectUrl values pointing to a domain they control. The victim receives an email from the legitimate dataCycle server containing a link with a valid reset token appended to the attacker URL. When the victim clicks the link, the token is transmitted to the attacker, who can then complete the reset and take over the account. User interaction is required for the attack to succeed.

Detection Methods for CVE-2026-32824

Indicators of Compromise

Outbound password reset or confirmation emails containing links where the host portion does not match the dataCycle application domain.
API requests to password reset or confirmation endpoints containing forwardToUrl or redirectUrl parameters with external hostnames.
Successful password reset events immediately followed by browser redirects to unfamiliar external domains.
Multiple password reset triggers originating from the same low-privileged API account within a short window.

Detection Strategies

Inspect API access logs for forwardToUrl and redirectUrl parameter values and flag any host not matching the approved application domains.
Correlate password reset request events with the destination host used in the delivered email link to identify mismatches.
Monitor authenticated API accounts for anomalous invocation rates of password reset and confirmation endpoints.

Monitoring Recommendations

Enable verbose logging on the dataCycle authentication and email dispatch subsystems, capturing all URL parameters embedded into outgoing messages.
Forward web application logs and mail relay logs to a centralized analytics platform for cross-source correlation.
Alert on any password reset completion followed by a redirect to a domain outside the organization's allowlist.

How to Mitigate CVE-2026-32824

Immediate Actions Required

Upgrade dataCycle-CORE to version 26.06.08 or later, which enforces host allowlisting on redirect parameters.
Audit recent password reset and confirmation activity for suspicious forwardToUrl or redirectUrl values pointing to external hosts.
Force password resets and invalidate active sessions for any account showing evidence of hijacked reset flows.
Review authenticated API accounts and revoke credentials that are not required for production operation.

Patch Information

The vendor released a fix in dataCycle-CORE version 26.06.08. The patch introduces host allowlisting for forwardToUrl and redirectUrl values before they are embedded into email workflows or used as post-reset browser redirects. Details are published in the GitHub Security Advisory GHSA-8jfx-wpjg-hf38.

Workarounds

Restrict API access to the password reset and confirmation endpoints using network controls or web application firewall rules until the upgrade is applied.
Deploy a WAF rule that rejects requests to reset and confirmation endpoints when forwardToUrl or redirectUrl parameters contain hosts outside an approved allowlist.
Reduce the token lifetime for password reset and confirmation links to shrink the window for token capture abuse.

bash

# Example WAF rule concept: block external redirect targets on reset endpoints
# Reject requests where forwardToUrl or redirectUrl point outside trusted domain
SecRule REQUEST_URI "@rx /(password_reset|confirm)" \
  "chain,deny,status:403,id:1032824,msg:'CVE-2026-32824 external redirect blocked'"
  SecRule ARGS:forwardToUrl|ARGS:redirectUrl "!@rx ^https?://([a-z0-9-]+\.)*trusted-domain\.example/"
