This medium-severity CVE scores 4.3 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 89% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Prior to 27.0.3 and 28.0.1, the redirect parameter upon login to LORIS was not validating the value of the redirect as being within LORIS, which could be used to trick users into visiting arbitrary URLs if they are given a link with a third party redirect parameter. This vulnerability is fixed in 27.0.3 and 28.0.1.
