CVE-2026-90528 Details
Description
A flaw has been found in TDuckApp tduck-platform up to 5.3. Affected by this vulnerability is an unknown functionality of the file tduck-front/src/views/form/write/index.vue of the component Form Write View. This manipulation of the argument submitShowCustomPageContent causes cross site scripting. The attack is possible to be carried out remotely. The project was informed of the problem early through an issue report but has not responded yet.
A cross-site scripting (XSS) vulnerability has been identified in TDuckApp tduck-platform versions through 5.3. The issue arises in the Form Write View component, specifically within the file 'tduck-front/src/views/form/write/index.vue'. The vulnerability is triggered by manipulating the 'submitShowCustomPageContent' argument, allowing for remote execution of the attack. This flaw was reported to the project, but no response has been received yet.
It is recommended to change the success page to use text interpolation instead of HTML rendering. If rich text is necessary, a strict whitelist sanitizer should be applied before rendering, disallowing event attributes, script protocols, and dangerous SVG/MathML. Additionally, the backend should impose content length and allowance constraints on 'submitShowCustomPageContent' and implement security regression tests for the 'form owner save' to 'anonymous user submission' workflow.
