CVE-2026-96257
CriticalCVSS 10.0Summary
A flaw has been found in Fast FAC1203R Gigabit Edition 2.0.4 in the copy_msg_element function of the Device Discovery Service component. Input manipulation can lead to a stack-based buffer overflow, and the attack can be executed remotely. The exploit has been published and may be used; the vendor did not respond to the disclosure.
Risk Assessment
A remote attacker can use the publicly available exploit to trigger a stack-based buffer overflow, potentially causing device crashes or arbitrary code execution.
Recommendation
Isolate the device from untrusted networks as soon as possible, restrict access to the Device Discovery Service, and contact the vendor for a fix.

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.

A server-side request forgery (SSRF) vulnerability was identified in the notebook viewer of GitHub Enterprise Server. The notebook viewer validated the scheme and host of a user-supplied URL but did not validate the port, allowing requests to be directed to internal services listening on other ports of the same appliance. Response bodies were not returned to the requester, but response timing acted as an oracle that allowed instance secrets to be extracted character by character. An extracted secret could then be used in a separate interaction with an internal service to obtain remote code execution on the appliance. Exploitation required network access to the instance and was unauthenticated when private mode was disabled, or required any authenticated user when private mode was enabled. This vulnerability affected GitHub Enterprise Server versions 3.17 through 3.22 and was fixed in versions 3.22.1, 3.21.6, 3.20.8, 3.19.12, 3.18.15, and 3.17.21. This vulnerability was reported through the GitHub Bug Bounty program.
