dataCycle-CORE: URL Redirection to Untrusted Site
CVE-2026-32824 is a high-severity URL redirection to untrusted site vulnerability in dataCycle-CORE from Datacycle-engine, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected dataCycle-CORE versions: <= 25.07.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of dataCycle-CORE you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, a low-privileged authenticated API user can supply `forwardToUrl` and `redirectUrl` values when triggering password reset or confirmation flows. Those values are then embedded into the outgoing email workflow without host allowlisting. This creates two related abuse paths: - password reset or confirmation links can be sent to a victim with the token already attached to an attacker-controlled `forwardToUrl` - after a legitimate password reset completes, the browser is redirected to attacker-controlled `redirectUrl` In practice, this can be used for phishing, token capture, confirmation hijacking, or steering a victim from a trusted email into an attacker domain. This is patched in version 26.06.08.

The underlying weakness: URL Redirection to Untrusted Site
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
How developers prevent this class of flaw
- Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to /login.asp and ID 2 could map to http://www.example.com/. Features such as the ESAPI AccessReferenceMap provide this capability.
- Ensure that no externally-supplied requests are honored by requiring that all redirect requests include a unique nonce generated by the application. Be sure that the nonce is not predictable (CWE-330).
