{"id":"CVE-2026-55147","published":"2026-10-30T22:16:54.807","lastModified":"2026-10-30T22:16:54.807","description":"LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. In versions from 22.0.0 prior to 27.0.4 and from 28.0.0 prior to 28.0.2, the `API` for the `imaging_browser` module permits edits to imaging data without checking the frontend permissions that restrict editing in Imaging Browser. An authenticated `API` caller can therefore modify imaging data without the required edit authorization. Deployments that no longer use the `API` can disable it to remove access to this endpoint. This issue is fixed in versions 27.0.4 and 28.0.2.","cvssScore":6.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/aces/Loris/commit/b13053597530ee33fbced35085d2490bc9ccc03a","tags":[]},{"url":"https://github.com/aces/Loris/pull/10531","tags":[]},{"url":"https://github.com/aces/Loris/releases/tag/v27.0.4","tags":[]},{"url":"https://github.com/aces/Loris/releases/tag/v28.0.2","tags":[]},{"url":"https://github.com/aces/Loris/security/advisories/GHSA-m48r-jv24-jjcx","tags":[]}],"exploitRefs":[{"url":"https://github.com/aces/Loris/commit/b13053597530ee33fbced35085d2490bc9ccc03a","tags":[]},{"url":"https://github.com/aces/Loris/pull/10531","tags":[]},{"url":"https://github.com/aces/Loris/releases/tag/v27.0.4","tags":[]},{"url":"https://github.com/aces/Loris/releases/tag/v28.0.2","tags":[]},{"url":"https://github.com/aces/Loris/security/advisories/GHSA-m48r-jv24-jjcx","tags":[]}],"hasPoc":true,"ai":null}
