## 2.15.1 (2025-10-16)
This version includes bug fixes regarding config deployments and improvements
to allow for better debugging of problems related to JSON-RPC cluster
communication.
This release fixes multiple security issues. Two of them allow authenticated
API users to learn restricted information or crash Icinga 2. A third issue
affects the scripts provided with Icinga 2 and allows a limited privilege
escalation where the Icinga 2 daemon user can trick root into sending signals to
arbitrary processes.
In addition, this version also includes bug fixes regarding config deployments
and improvements to allow for better debugging of problems related to JSON-RPC
cluster communication.
Note that one fix affects the logrotate configuration. If it was modified
locally, it might not be updated automatically by the package manager and
applying the changes manually is necessary. For details, please check the
[upgrading docs](https://icinga.com/docs/icinga-2/latest/doc/16-upgrading-icinga-2/#upgrading-to-2-15-1).
* Don't send signals as root in safe-reload script and logrotate config. #10590
### Security
* CVE-2025-61907: Prevent API users from accessing variables and objects they
don't have access to within filter expressions. This allowed authenticated
API users to learn information they aren't allowed to access directly.
* CVE-2025-61908: Add a missing null pointer check while evaluating
expressions. This allowed authenticated API users to crash the Icinga 2
daemon by supplying a crafted filter expression.
* CVE-2025-61909: Don't send signals as root in safe-reload script and
logrotate config. This allowed a limited privilege escalation from the Icinga
2 service user to root. The scope is limited to sending SIGHUP or SIGUSR1 to
an arbitrary process. #10590
* Windows: Update to OpenSSL 3.0.18. #10591
### Bugfixes
* When a reload triggered from Icinga Director (or the /v1/config API) fails,
the corresponding state is cleared, allowing to deploy a new config without
having to restart Icinga 2 manually first. #10584
### Enhancements
* Add JSON-RPC utilization metrics and troubleshooting docs. #10586
* When sending cluster messages to other zones, prefer endpoints in the order
as specified in the zone configuration. #10587
* Track the number of JSON-RPC messages received for each message type per
endpoint. #10585
* Add support for building with Boost v1.89 and use it on Windows. #10578
* Windows: Update to OpenSSL 3.0.18. #10591
