Overview This article details a security vulnerability, identified as CVE-2024-21635, affecting Memos, a privacy-first, lightweight note-taking service. The vulnerability resides in the handling of Access Tokens after a user changes their password. Specifically, existing Access Tokens remain valid even after a password change, potentially allowing malicious actors to maintain unauthorized access to a compromised account. Technical Details Memos relies on Access Tokens for authentication. When a user changes their password, the application *should* revoke all existing Access Tokens, forcing a re-authentication process. However, versions up to and including 0.18.1 fail to do so. This means that if an attacker has…

Overview A significant security vulnerability, identified as CVE-2025-9982, has been discovered in QuickCMS version 6.8. This flaw involves the storage of sensitive admin credentials in plaintext within a configuration file. An attacker who gains access to either the source code or the server’s file system can retrieve these credentials, potentially leading to privilege escalation and complete compromise of the affected QuickCMS installation. Technical Details The vulnerability stems from the inclusion of hardcoded administrator credentials directly within a configuration file. Instead of utilizing secure hashing and salting techniques, the username and password for the administrator account are stored in plaintext. This…

Overview CVE-2025-12149 describes a security vulnerability in Search Guard FLX versions 3.1.2 and earlier. This vulnerability allows for a Document-Level Security (DLS) bypass when searches are triggered from Signal’s watch functionality. While DLS is correctly enforced in other scenarios, queries initiated through Signal watches circumvent the DLS rules, potentially exposing sensitive data to unauthorized users. Technical Details The vulnerability stems from the way Search Guard FLX handles security contexts when a search is initiated from a Signal watch. Specifically, the DLS rules, designed to filter documents based on user roles and permissions, are not properly applied to searches originating from…

Overview A significant security vulnerability, identified as CVE-2025-11918, has been discovered in Rockwell Automation Arena®. This vulnerability involves a stack-based buffer overflow that could allow local attackers to execute arbitrary code on affected systems. The vulnerability is triggered by opening a specially crafted DOE file. Technical Details The vulnerability lies within the parsing logic of DOE files in Rockwell Automation Arena®. Specifically, the application fails to properly validate the size of data being written to a stack-allocated buffer. This lack of validation allows a malicious DOE file to write beyond the bounds of the buffer, potentially overwriting critical program data,…

Overview CVE-2025-8855 identifies a high-severity vulnerability affecting Optimus Software’s Brokerage Automation platform. This vulnerability allows for Authorization Bypass Through User-Controlled Key, Weak Password Recovery Mechanism for Forgotten Password, Authentication Bypass by Assumed-Immutable Data leading to Exploiting Trust in Client, Authentication Bypass, and the potential to Manipulate Registry Information. The affected versions are those before 1.1.71. Organizations using Optimus Brokerage Automation should immediately assess their exposure and apply the recommended mitigation steps. Technical Details CVE-2025-8855 encompasses several distinct but related security flaws: Authorization Bypass Through User-Controlled Key: The system allows unauthorized access to certain functionalities or data by improperly validating user-controlled…

Overview CVE-2025-11981 details a medium-severity SQL Injection vulnerability discovered in the School Management System – WPSchoolPress plugin for WordPress. This vulnerability affects all versions up to and including 2.2.23. The flaw allows authenticated attackers with administrator-level access or higher to inject arbitrary SQL commands into database queries. Exploitation could lead to the extraction of sensitive information, potentially compromising the entire WordPress installation. Technical Details The vulnerability stems from insufficient input sanitization on the ‘SCodes’ parameter used within the plugin’s code. Specifically, the plugin fails to properly escape user-supplied input and lacks sufficient preparation in its existing SQL queries. This allows…

Overview CVE-2025-55073 is a medium-severity vulnerability affecting Mattermost, a popular open-source collaboration platform. This flaw allows a remote attacker to edit arbitrary posts within the Mattermost environment by exploiting a weakness in the validation of the relationship between post updates and the MSTeams plugin OAuth flow. Technical Details The vulnerability lies in the improper validation of the association between a post being updated and the MSTeams plugin OAuth flow. Specifically, versions 10.11.x (

Overview CVE-2025-55070 is a medium severity security vulnerability affecting Mattermost versions prior to version 11. This vulnerability allows unauthenticated users to access sensitive information through WebSocket events due to a failure to enforce multi-factor authentication (MFA) on WebSocket connections. Technical Details The vulnerability arises because Mattermost versions before 11 do not properly enforce MFA requirements on WebSocket connections. WebSocket connections are persistent communication channels between the client and the server, used for real-time updates and event notifications. By bypassing MFA enforcement on these connections, an attacker can potentially subscribe to and receive sensitive data streamed through WebSocket events without authenticating.…

Overview CVE-2025-41436 describes a vulnerability in Mattermost versions prior to 11.0. This flaw allows regular users to bypass intended access controls and view content within archived channels, even if they should not have permission. The vulnerability stems from improper enforcement of the “Allow users to view archived channels” setting when accessing content via the “Open in Channel” functionality from followed threads. Technical Details The core issue resides in the insufficient validation of user permissions when accessing archived channel content through the “Open in Channel” feature linked from followed threads. While the “Allow users to view archived channels” setting is intended…

Overview CVE-2025-64444 details a critical OS Command Injection vulnerability affecting NCP-HG100 routers, specifically versions 1.4.48.16 and earlier. Successful exploitation of this vulnerability allows a remote attacker, with valid authentication credentials to the router’s management interface, to execute arbitrary operating system commands with root privileges. This represents a significant security risk, potentially allowing complete control over the affected device. Technical Details The vulnerability stems from improper neutralization of special elements within user-supplied input that is subsequently used in an OS command. This means that malicious code can be injected into a legitimate command, allowing the attacker to execute commands of their…
