CVE-2017-7295
HighSummary
A use-after-free vulnerability was discovered in Contiki Operating System 3.0 in httpd-simple.c within the cc26xx-web-demo httpd. Upon a connection close event, the http_state structure was not properly deallocated, leading to a NULL pointer dereference in the output processing function, resulting in a board crash.
Risk Assessment
This vulnerability can lead to system crashes, resulting in denial of service. It may affect the availability of applications running on this operating system.
Recommendation
It is recommended to update the Contiki operating system to the latest version to mitigate this vulnerability. Additionally, monitor system logs for potential attempts to exploit this flaw.

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.
