CVE-2016-4977
HighSummary
In Spring Security OAuth versions 2.0.0 to 2.0.9 and 1.0.0 to 1.0.5, the response_type parameter in authorization requests was processed as Spring SpEL. This allowed a malicious user to trigger remote code execution by crafting the value of the response_type parameter.
Risk Assessment
A malicious user could exploit this vulnerability to execute remote code, posing a serious threat to the security of the application and the organization's data.
Recommendation
It is recommended to update Spring Security OAuth to a version that is not vulnerable to this issue to minimize the risk of remote code execution.

The WP OAuth Server (Login with WordPress) WordPress plugin before 6.4.0 does not bind the OpenID Connect identity assertion it issues to the authorization grant being exchanged, returning instead the assertion belonging to whichever user authenticated most recently. This allows users with the Subscriber role and above to obtain a validly signed identity assertion for another user, including an administrator, and authenticate as them at any application that uses the site for single sign-on.

- CVE-2026-19202Critical
A caching flaw in the toolbox-core package of the mcp-toolbox-sdk-python SDK causes the same Google ID token to be cached and reused across different audiences. If an application uses the SDK to authenticate to two or more different audiences within the same process, the module-level token cache fails to key its cached tokens by the requested audience. Consequently, a valid, unexpired token minted for a sensitive service (Service A) can be retrieved from the cache and sent to a secondary service (Service B). An attacker who operates, compromises, or monitors traffic to Service B can capture this token and replay it to impersonate the victim application against Service A.
