CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-26199 is a critical-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Vishalmathur Cloudclassroom-Php Project. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 40th 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 map to SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CloudClassroom-PHP-Project v1.0 contains an insecure credential transmission vulnerability tracked as CVE-2025-26199 and assigned CWE-319. The application sends user passwords in plaintext over unencrypted HTTP during login, leaving credentials exposed on the network. The flaw carries a CVSS 3.1 base score of 9.8 reflecting network attack vector, low complexity, and no required authentication or user interaction.
A remote attacker positioned on the same network segment, such as a public Wi-Fi network or a compromised router, can perform a man-in-the-middle interception to capture valid login credentials. Once obtained, the attacker may authenticate and abuse administrative functions including file-upload capabilities, potentially resulting in remote code execution depending on the deployment environment.
The two provided references consist of a technical gist and a GitHub repository that document the issue but contain no official advisories, vendor patches, or mitigation guidance. The associated EPSS score remains flat at 0.0303 with no material increase since disclosure.

Vulnerability Data
CloudClassroom-PHP-Project v1.0 is affected by an insecure credential transmission vulnerability. The application transmits passwords over unencrypted HTTP during the login process, exposing sensitive credentials to potential interception by network-based attackers. A remote attacker with access to the same network (e.g.,…

public Wi-Fi or compromised router) can capture login credentials via Man-in-the-Middle (MitM) techniques. If the attacker subsequently uses the credentials to log in and exploit administrative functions (e.g., file upload), this may lead to remote code execution depending on the environment.

Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.
Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.
Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.
Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
