Hi there Akshayaa Kalyanavenkatesh
Thanks for using QandA platform
The libs you listyed arare indeed outdated and might contain known vulnerabilities.
Unfortunately, SSRS uses these libraries as part of its built-in UI, and Microsoft doesn’t provide an official way to update or patch them manually without breaking the SSRS functionality or supportability.
try to Host custom reports in an external app (e.g., ASP.NET with up-to-date libs) and connect to SSRS via API.
Use (CSP) headers or Web Application Firewall (WAF) to mitigate risks.
Restrict access to the SSRS web portal to trusted users/networks only.
If this helps kindly accept the answer thanks much.
