Reported on

Oct 7th 2021

✍️ Description

HTTPOnly attribute is not set for session cookies "OJSSID" in the application.

Proof of Concept

Check this for POC: Image


When a cookie doesn’t have an HttpOnly flag, it can be accessed through JavaScript, which means that an XSS could lead to cookies being stolen. These include session cookies that can make it easier to achieve account/session takeover.

Not necessarily a comment on this specific issue, but a heads-up that I'm going to be intentionally slow to confirm and resolve trivial reports. It looks like there's a bit of a gold rush on this platform and I don't want to encourage a flood of low-value entries.
