CVE-2026-84839 Details
Description
A vulnerability was determined in tsi-coop tsi-dpdp-cms up to 0.5.0. Affected by this issue is some unknown functionality of the file web.xml of the component Admin Console/DPO Compliance Console. Executing a manipulation can lead to missing authentication. It is possible to launch the attack remotely. The exploit has been publicly disclosed and may be utilized. Upgrading to version 0.5.1 can resolve this issue. It is suggested to upgrade the affected component.
A vulnerability exists in TSI-Coop TSI-DPDP-CMS versions through 0.5.0, where all admin and Data Protection Officer (DPO) console pages are served without authentication. This issue arises from the application's authentication mechanism, which relies on client-side JavaScript to check for a token in local storage. As a result, any non-browser HTTP client can easily bypass this check and access sensitive internal API information. The vulnerability has been publicly disclosed and exploited.
Users are advised to upgrade to TSI-DPDP-CMS version 0.5.1, which addresses the authentication issue by implementing server-side checks for all console pages. Instructions for upgrading can be found in the TSI-DPDP-CMS release notes.
