Parameter Value
CVSS 7.1 (HIGH)
Type CWE-862 (Missing Authorization)
Vendor Cisa
Public PoC No

A deployment mode intended to expose only read access to stored data proxies a set of application programming interface routes without restricting which request methods are allowed. One such route accepts a request that creates or overwrites a stored record, including an attacker-chosen identifier, using the application's own elevated backend credentials. This allows an authenticated user on a deployment intended to be read-only to forge or overwrite stored records that should not be modifiable in that deployment mode.
