An attacker can leverage several vulnerabilities within the ILIAS e-learning platform to bypass security controls, disclose sensitive information, and execute Cross-Site Scripting (XSS) attacks, potentially leading to unauthorized access, data compromise, and client-side code execution.

A remote, unauthenticated attacker can exploit a low-severity vulnerability within the GStreamer webrtcbin component to bypass existing security measures, potentially allowing for the circumvention of protective mechanisms without further details on specific impact.

A remote, unauthenticated attacker can exploit a Cross-Site Scripting (XSS) vulnerability in the 'io.undertow.jastow' component of Red Hat JBoss Enterprise Application Platform, allowing injection of malicious scripts into web pages which can lead to session hijacking, data theft, or defacement.

CrowdStrike details the internal mechanisms of Microsoft's ClickOnce technology, a legitimate software deployment method that offers minimal user interaction and no administrative privilege requirements, making it a double-edged sword with significant potential for threat actor abuse in malware distribution and persistence.

The DoLogin Security plugin for WordPress, in all versions up to and including 4.3, is vulnerable to authentication bypass (CVE-2026-14495) due to insufficient randomness in magic-link token generation, allowing unauthenticated attackers to brute-force and reconstruct valid passwordless login tokens for any user, including administrators, and gain full control.

Authenticated attackers with Custom-level access or higher can exploit CVE-2026-14489, a missing file type validation vulnerability (CWE-434) in the `connect()` function of the WHMCS Bridge plugin for WordPress versions up to and including 6.9, to upload arbitrary files, potentially leading to remote code execution.

The WP Learn Manager plugin for WordPress, in versions up to and including 1.1.8, is vulnerable to an authorization bypass (CVE-2026-12153) allowing unauthenticated attackers to install and activate arbitrary plugins from the WordPress.org repository, potentially leading to full site compromise.

CrowdStrike has identified 18 new prompt injection techniques, expanding its taxonomy to over 200 methods, which enable adversaries to manipulate AI systems and agents through hidden context, delayed triggers, semantic constraints, boundary spoofing, and social engineering to bypass security measures, leading to modified behavior, data exfiltration, or malicious command execution in AI-driven applications and agents like chatbots or those running in Kubernetes.

CrowdStrike's AI security research team has identified 18 new prompt injection techniques, expanding its taxonomy to over 200 methods, which adversaries can use to manipulate AI systems and agents through hidden context, delayed triggers, semantic constraints, boundary spoofing, and social engineering, potentially leading to agent hijacking, data exfiltration, or system compromise by causing them to execute unintended commands like shell scripts or SQL queries.

Adversaries are leveraging sophisticated prompt injection techniques, including hidden rules, token suppression, payload decomposition, and special token injection, against AI agents to manipulate their behavior, bypass safety mechanisms, and achieve objectives such as data exfiltration or arbitrary command execution, posing a critical threat to AI-powered systems.

The legacy `oidcProvider` and `mcp` plugins in the `better-auth` library versions prior to 1.6.11 are vulnerable to CVE-2026-53512, an OAuth refresh-token replay attack where the plugins fail to verify the `client_secret` of confidential clients during the `refresh_token` grant, allowing an attacker who obtains a valid `refresh_token` and `client_id` to indefinitely mint new access tokens and impersonate the client for unauthorized resource access.
