Details
A vulnerability was found in Eclipse KeyPont (the affected version unknown) and classified as critical. Affected by this issue is the function JwksTrustStore.Get of the component JWKS Cache. The manipulation of the argument kid with an unknown input leads to a return value vulnerability. Using CWE to declare the problem leads to CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions. Impacted is confidentiality, integrity, and availability. CVE summarizes:
`JwksTrustStore.Get` assigned each parsed key to the function's **named return value** while refreshing the JWKS cache. When the requested `kid` was not present, the trailing naked `return` handed the caller the last key in the JWKS document together with a `nil` error — a confidently wrong answer instead of "not found".
