Detection Methods for CVE-2026-13292
Detection Strategies
- Inventory every instance of IBM MQ and compare the running version with the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Run an authenticated vulnerability scan once your scanner ships a check for this CVE.
Monitoring Recommendations
- Forward IBM MQ application, access and audit logs to your SIEM for retrospective hunting.
- Alert on new processes, configuration changes or outbound connections from the affected service.
- Track the vendor advisory and the CISA KEV catalog for changes in exploitation status.
How to Mitigate CVE-2026-13292
Immediate Actions Required
- Apply the fixed version of IBM MQ named in the vendor advisory.
- Prioritize internet facing and business critical instances first.
- Rescan after the change to confirm the exposure is closed.
Workarounds
- If patching must wait, restrict network access to the affected service and place it behind authentication or a web application firewall rule.

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. The RC endpoint `options/set` is exposed without `AuthRequired: true`, but it can mutate global runtime configuration, including the RC option block itself. Starting in version 1.45.0 and prior to version 1.73.5, an unauthenticated attacker can set `rc.NoAuth=true`, which disables the authorization gate for many RC methods registered with `AuthRequired: true` on reachable RC servers that are started without global HTTP authentication. This can lead to unauthorized access to sensitive administrative functionality, including configuration and operational RC methods. Version 1.73.5 patches the issue.
AzuraCast through 0.23.8 fails to remove frontend_config.custom_config in PUT /station/{id}/profile/edit for users lacking the Manage station broadcasting permission, and the stored JSON is written verbatim as key=value lines into the Shoutcast sc_serv.conf file. An authenticated user with only the Manage station profile permission can override adminpassword, password, and portbase, or inject arbitrary directives via newlines in keys, hijacking the station's Shoutcast frontend.
IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote attacker to obtain sensitive information due to external control of system configuration.
OpenClaw before 2026.3.22 contains an environment variable override handling vulnerability that allows attackers to bypass the shared host environment policy through inconsistent sanitization paths. Attackers can supply blocked or malformed override keys that slip through inconsistent validation to execute arbitrary code with unintended environment variables.
A privilege escalation vulnerability exists in the internal Command-Line Interface (CLI) authorization handling mechanism of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user or local process that can manipulate the process execution environment can bypass Role-Based Access Control (RBAC) validation checks. Successful exploitation allows an attacker to elevate privileges to root
Cursor is a code editor built for programming with AI. Prior to 2.3, hen the Cursor Agent is running in Auto-Run Mode with Allowlist mode enabled, certain shell built-ins can still be executed without appearing in the allowlist and without requiring user approval. This allows an attacker via indirect or direct prompt injection to poison the shell environment by setting, modifying, or removing environment variables that influence trusted commands. This vulnerability is fixed in 2.3.
