CVE-2016-3403
HighSummary
Multiple cross-site request forgery (CSRF) vulnerabilities in the Admin Console in Zimbra Collaboration before 8.6.0 Patch 8 allow remote attackers to hijack the authentication of administrators for requests that (1) add, (2) modify, or (3) remove accounts. The issue arises from the failure to use a CSRF token and perform referer header checks.
Risk Assessment
Attackers can exploit these vulnerabilities to gain unauthorized control over administrator accounts, potentially leading to serious security breaches within the organization.
Recommendation
It is recommended to update Zimbra Collaboration to version 8.6.0 Patch 8 or later to mitigate these vulnerabilities and implement additional security measures such as CSRF token verification.

- 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.

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.

Multiple cross-site request forgery (CSRF) vulnerabilities in the Admin Console in Zimbra Collaboration before 8.6.0 Patch 8 allow remote attackers to hijack the authentication of administrators for requests that (1) add, (2) modify, or (3) remove accounts by leveraging failure to use of a CSRF token and perform referer header checks, aka bugs 100885 and 100899.
