Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The /irmdata/api/ endpoints exposed by the IRM Next Generation booking engine authenticates requests using HMAC tokens. These tokens are however exposed in a JavaScript file loaded on the client side, thus rendering this extra safety mechanism useless.
