Core-Bot: Exposure of Sensitive Information to an Unauthorized Actor
CVE-2025-65957 is a high-severity exposure of sensitive information to an unauthorized actor vulnerability in Core-Bot from Intercore-Productions, with a CVSS 4.0 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected Core-Bot versions: < dffe050d565a580edfcd0242efa45da88ab31260. The record does not name a fixed version, so check the vendor advisory. 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
- Check which version of Core-Bot you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Intercore-Productions | Core-Bot | < dffe050d565a580edfcd0242efa45da88ab31260 | Not stated |

Official description
Core Bot Is an Open Source discord bot made for maple hospital servers. Prior to commit dffe050, the API keys (SUPABASE_API_KEY, TOKEN) are loaded using environment variables, but there are cases in code (error handling, summaries, webhooks) where configuration summaries may inadvertently leak sensitive data (e.g., by failing to redact data in summary embeds or logs). This issue has been patched via commit dffe050.

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.
