Description
Summary
Session cookie is without Secure and HTTPOnly flags.
Details
Please take a look at this part of code (PoC screenshot) or check code directly (provided in Occurrences section below)

Proposed remediation: add Secure and HTTPOnly flags for cookies.
It could be like this:
document.cookie = tprh=${tprh};path=/;Secure;HttpOnly;;
PoC
Screenshot:
Impact
Secure: This flag indicates that the cookie should only be sent over secure HTTPS connections. Without this flag, the cookie will be sent over both HTTP and HTTPS connections, which could expose it to interception or tampering if the connection is not secure. HttpOnly: This flag prevents the cookie from being accessed by client-side JavaScript. It helps mitigate certain types of attacks, such as cross-site scripting (XSS), by preventing malicious scripts from accessing the cookie's value.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for taipy, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update taipy to 4.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r3jq-4r5c-j9hp is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
