Technical description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to 2.3.2, the terminal WebSocket accepts a user-controlled hostConfig.id and src/backend/ssh/host-resolver.ts resolves that host without requiring ownership or explicit access. When no credential is shared with the requester, resolveHostById performs an owner credential fallback, and src/backend/ssh/terminal.ts combines that credential with attacker-controlled ip, port, and username values. An authenticated low-privileged user can therefore make Termix authenticate to an attacker-controlled SSH server and disclose another user's stored SSH password or private-key material while the victim user's data key is unlocked. This issue is fixed in version 2.3.2.

———OpenProject is open-source, web-based project management software. In version 17.5.1 and earlier, an authenticated non-admin project member can request the inplace-edit dialog for a raw custom_field_ project attribute. The dialog path resolves the project custom field by its raw identifier without enforcing the normal admin_only visibility scope and renders the stored custom-field comment in read-only mode. This discloses hidden comment text but does not disclose the custom-field value or permit writes or mutation. This issue is reported as fixed in version 17.6.0.7h CVE-2026-766346.5 MED

———WeGIA before 3.9.2 contains an insecure direct object reference vulnerability in the employee profile page that allows authenticated attackers to access arbitrary employee records by injecting an id_pessoa parameter through a request extraction function that overwrites the session-derived identifier. Attackers can enumerate all user identifiers to retrieve full profile data for any employee account, including name, CPF, address, contact details, and administrative flags.9h CVE-2026-766338.1 HIG

———WeGIA before 3.9.2 contains an authorization bypass vulnerability in the password change flow that allows any authenticated user to change their account password without providing existing credentials by exploiting the unconditional exclusion of the alterarSenha method from permission checks in controle/control.php. Attackers can manipulate the redir parameter to point to alterar_senha.php, routing through verificarSenhaConfig() instead of verificarSenha() to bypass current password verification and convert temporary session access into permanent account takeover.8h CVE-2026-64969—

———ATutor is vulnerable to Insecure Direct Object Reference (IDOR) attack in profile picture related endpoints. Any authenticated user, including a student, can supply another user's member_id in a POST request to the profile album endpoint and permanently delete that user's profile picture, including those of instructors and administrators. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.8h CVE-2026-64965—

———ATutor is vulnerable to Missing Authorization Check on Test and Question Import endpoints. A low-privileged authenticated user (e.g. a student) enrolled in a course can bypass authorization checks by sending requests directly to the backend import endpoints, allowing the unauthorized import of tests and questions within a course. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.8h CVE-2026-64961—

———ATutor is vulnerable to authentication bypass . Although a token validation check is present in the auto-login functionality, the values required for token validation remain uninitialized in certain code paths. An unauthenticated attacker who can determine a user's identifier and registration timestamp can generate a valid token and authenticate as an existing user, including administrator, without knowing the password. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.8h
