CVE-2026-44828
CriticalCVSS 9.3Summary
Qexo versions 4.0.0 through 4.2.0 expose /api/init_step/ without authentication, authorization, or a setup-completion guard. An unauthenticated requester with a valid CSRF token can reset the INIT setting and re-enter the setup flow, potentially exposing stored PROVIDER configuration including credentials.
Risk Assessment
An attacker can access sensitive configuration data, including service credentials, potentially leading to security breaches and account takeover.
Recommendation
Upgrade Qexo to version 4.2.0 or later. Additionally, restrict access to the /api/init_step/ endpoint and monitor logs for unauthorized attempts.

Rapyd Admin versions 9.0.0 before 9.20.0 contain hard-coded credentials that allow remote unauthenticated attackers to gain super-admin access through an admin@laravel account with password admin. The account is seeded by the installer and silently re-created on every rpd:make run, bypassing authorization and tenant scoping.

IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 are vulnerable to privilege escalation. An authenticated attacker could craft a malicious request that bypasses additional authorization and input validation checks to execute malicious code and gain elevated privileges.
- CVE-2026-109575Critical
HAProxy Data Plane API versions 2.2.0 through 3.4.3 (and corresponding Enterprise Edition releases) have process-global authentication logic that improperly drops security controls across multiple transport types. When a TLS CA is configured and a numeric TLS port is specified, the application globally disables Basic authentication on its shared internal request handler, allowing unauthenticated attackers to reach affected HTTP or UNIX endpoints and completely bypass credentials to gain full API administrative access.
- CVE-2026-108362Critical
In Privasys Remote Attestation TLS Clients prior to 0.11.0, TEE attestation evidence is accepted without requiring an explicitly authorized platform identity. A network attacker can forge evidence or extract attestation secrets from a compromised unrevoked platform, causing the verifier to accept valid measurements from a different unrevoked TEE platform as though they came from the intended Attester. This allows impersonation of the attested TLS endpoint.
Original NVD description (English source)
Qexo is an open source online editor for static blogs. From 4.0.0 until 4.2.0, Qexo exposes /api/init_step/ through init_step_api without authentication, authorization, or a setup-completion guard. An unauthenticated requester with a valid CSRF token obtained from a public page can submit the first initialization step and reset the INIT setting, causing the instance to re-enter the setup flow. The setup response and /init/ page can expose stored PROVIDER configuration, including service credentials, in frontend content. This issue is fixed in version 4.2.0.
