CVE-2017-2819
HighSummary
A heap-based buffer overflow vulnerability exists in the Hangul Word Processor component (version 9.6.1.4350) of Hancom Thinkfree Office NEO 9.6.1.4902. A specially crafted document stream can cause an integer underflow leading to a buffer overflow and potential code execution under the application's context.
Risk Assessment
An attacker can entice a user to open a malicious document, which may lead to unauthorized code execution on the system. This poses a serious threat to data security and system integrity.
Recommendation
It is recommended to update the software to the latest version to mitigate this vulnerability. Additionally, users should be warned against opening documents from unknown sources.

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.
