CVE-2023-40660 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2025-08-30 6.6 Medium
A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.

CVE-2024-24830 1 Openobserve 1 Openobserve 2025-08-27 10 Critical
OpenObserve is a observability platform built specifically for logs, metrics, traces, analytics, designed to work at petabyte scale. A vulnerability has been identified in the "/api/{org_id}/users" endpoint. This vulnerability allows any authenticated regular user ('member') to add new users with elevated privileges, including the 'root' role, to an organization. This issue circumvents the intended security controls for role assignments. The vulnerability resides in the user creation process, where the payload does not validate the user roles. A regular user can manipulate the payload to assign root-level privileges. This vulnerability leads to Unauthorized Privilege Escalation and significantly compromises the application's role-based access control system. It allows unauthorized control over application resources and poses a risk to data security. All users, particularly those in administrative roles, are impacted. This issue has been addressed in release version 0.8.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
