Deeper analysis
CVE-2026-2058 is a SQL injection vulnerability in the mathurvishal CloudClassroom-PHP-Project up to commit 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The flaw affects an unknown function within the file /postquerypublic.php of the Post Query Details Page component. It arises from improper handling of the 'gnamex' argument, enabling SQL injection attacks. The product follows a rolling release strategy, so specific affected or patched versions cannot be identified.
The vulnerability has a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating it can be exploited remotely by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption via injected SQL payloads.
Advisories from VulDB (ctiid.344618, id.344618) and related GitHub repositories detail the issue, noting that an exploit has been published and is available for use. The vendor was contacted early for disclosure but provided no response. No official patches or mitigations are specified due to the rolling release model; practitioners should review the project repositories for any community updates and implement input validation or web application firewalls to block SQL injection attempts on the affected endpoint.
