CityPLus: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2025-11151 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in CityPLus from Beyaz Bilgisayar Software Design Industry and Trade Ltd. Co., with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version V24.29500.1.0 as the first without the flaw, so updating CityPLus to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.28% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update CityPLus to V24.29500.1.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
