CVE-2026-11979
Description détaillée
libxml2 is vulnerable to multiple stack-based buffer overflows in the xmlcatalog utility when running in --shell mode. The usershell() function processes user input using fixed-size stack buffers without proper bounds checking. By supplying an overly long input line, an attacker can overflow internal buffers (command, arg, and argv) during input parsing. This results in memory corruption within the stack frame. Successful exploitation may cause a crash or potentially allow arbitrary code execution in the context of the xmlcatalog process. This issue has been fixed in the commit c2e233fc. NOTE: The maintainers of this project did not agree that this issue is a vulnerability and considered it a bug.

CVE-2026-13752
Improper neutralization of parameters in Snowflake CLI versions prior to 3.19 allowed unintended SQL execution. An attacker could exploit this by supplying crafted values to vulnerable command paths, causing Snowflake CLI to execute unintended SQL in the context of the user’s Snowflake session. Successful exploitation required crafted values to reach vulnerable parameters, including through socially engineered input, malicious repository configuration, or compromised automation feeding external values into the CLI, and impact is limited by the privileges assigned to the active session. The fix is available in Snowflake CLI version 3.19, and users must manually upgrade.
CVE-2026-13751
Improper handling of untrusted remote references in Snowflake CLI versions prior to 3.19 allowed server-side request forgery. The SQL statement reader's !source/!load directives could reference remote URLs that were retrieved at runtime without sufficient restriction on the request destination. By supplying crafted SQL content processed through a vulnerable command path, an attacker could cause the victim's environment to issue unintended outbound requests to internal or otherwise non-public network locations, and could cause remote SQL content to be retrieved and executed in the context of the victim user's session. Successful exploitation requires the victim to process attacker-controlled content through a vulnerable command path and is limited by the privileges available to that session and environment. The fix is available in Snowflake CLI version 3.19, which adds an option to disable remote URL retrieval.
CVE-2026-13591
A weakness has been identified in DeepMyst Mysti 0.4.0. Affected is the function _isTrackedConversation of the file src/managers/ChannelBridge.ts of the component Contact Tracking. This manipulation of the argument _channelType causes improper authorization. The attack may be initiated remotely. A high degree of complexity is needed for the attack. The exploitability is told to be difficult. The exploit has been made available to the public and could be used for attacks. Patch name: 9b4aff0f106db424aa45a35aa89dd0b8f2eb9a48. It is suggested to install a patch to address this issue.
