Summary

CVE-2025-7186 is a low-severity Injection (CWE-74) vulnerability in Fabian Chat System. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 41.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).

Deeper analysis

CVE-2025-7186 is a SQL injection vulnerability in code-projects Chat System 1.0, published on 2025-07-08. The issue affects unknown processing in the file /user/fetch_chat.php, where manipulation of the ID argument enables the injection. Rated as critical with a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), it maps to CWE-74 and CWE-89.

A remote attacker can exploit this vulnerability by manipulating the ID parameter in /user/fetch_chat.php. Exploitation requires low privileges (PR:L), low attack complexity, and no user interaction, allowing network-based initiation. Successful attacks result in low impacts to confidentiality, integrity, and availability.

Advisories referenced on VulDB (ctiid.315125, id.315125, submit.607195) and a GitHub repository (LamentXU123/cve/sql_fetch_chat.md) provide further details, while the project site is at code-projects.org. The exploit has been disclosed publicly and may be used, with no specific patch or mitigation steps detailed in the available information.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of the ID parameter in fetch_chat.php to block SQL injection payloads before they reach the database.

AC-6 Least Privilege partial match
prevent

Enforces least privilege so that only the minimal database permissions are granted to the chat-system account, limiting the impact of a successful ID-based injection.

SI-4 System Monitoring partial match
detect

Enables monitoring of database query patterns and anomalies originating from /user/fetch_chat.php to identify exploitation attempts in progress.
