CVE-2026-76406

Information Disclosure through REST API Authentication in Splunk SOAR

In Splunk SOAR versions below 8.7.0, an unauthenticated user with access to encrypted credential data from an affected Splunk SOAR instance could submit Basic authentication data to the Representational State Transfer (REST) API to expose and decrypt that encrypted credential data. The vulnerability is possible because Splunk SOAR decrypts encrypted Basic authentication values before completing authentication checks. The attack requires the unauthenticated user to have encrypted credential data from an affected Splunk SOAR instance. The unauthenticated user should not be able to exploit the vulnerability at will. For more information see Using the REST API reference for Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/8.5.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises) in the Splunk documentation.

CVE-2026-96512

Sudo: sudo: tz environment variable allows bypass of notbefore/notafter time-based authorization

A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Because sudo is a setuid-root program, an unprivileged local user can set TZ to an extreme timezone offset to shift the authorization window by up to approximately 25 hours, causing expired rules to be treated as valid. This allows the user to execute commands outside the intended time window. Authentication is not bypassed; only the time-based authorization check is affected.
