Technical description

The system accepts authentication requests without sufficient validation to enforce tenant isolation when using Email OTP, SMS OTP, or Magic Link as first-factor authenticators. This failure to adequately separate user data between tenants can lead to the exposure of personally identifiable information. Successful exploitation allows an attacker to disclose personally identifiable information of users in different tenants, resulting in privacy violations and potential regulatory non-compliance. This may include unauthorized access to user details such as mobile numbers.

———Dell Virtual Storage Integrator for VMware vSphere Client, versions prior to 10.11.1.0, contain(s) a Sensitive Information Disclosure vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability, leading to information disclosure and session hijacking. This vulnerability is considered critical as it allows an unauthenticated attacker to obtain active session credentials and fully impersonate authenticated users, including administrators. Dell recommends customers to upgrade at the earliest opportunity.8h CVE-2026-163164.3 MED

———OMICRON StationGuard 4.00 contains an improper input validation vulnerability in its IEC 61850 Sampled Values (SV) frame processing. A specially crafted SV frame can cause the affected process to terminate, disrupting alert processing for Sampled Values traffic. The vulnerability does not affect overall system availability or the processing of other traffic types, and the process is automatically restarted, and the failure is immediately reported to the user.7h CVE-2026-578179.8 CRI

——0The OpenID Connect Core 1.0 specification mandates that the RP MUST validate the `c_hash` parameter when operating in the Hybrid Flow. If an Apache CXF RP is integrated with a non-compliant or misconfigured Identity Provider (IdP) that omits the `c_hash`, the RP becomes vulnerable to Authorization Code Substitution/Injection attacks. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.7h CVE-2024-103024.0 MED

——0The user self-signup flow in multiple WSO2 products fails to adequately validate user-supplied input. This weakness allows arbitrary unvalidated data to be included within user claims, which are then used by downstream processes. Allowing unvalidated input into user claims can lead to various security risks. Malicious or malformed data injected during signup could be processed by other parts of the application, potentially enabling attacks such as content manipulation, redirection, user interface inconsistencies, unauthorized actions, and data exposure. The actual impact depends on how the compromised data is consumed and the privileges associated with the affected users.8h CVE-2026-180507.5 HIG

——0The Events Manager WordPress plugin before 7.4 does not perform any authorization check on a REST route that serves temporarily stored file uploads, allowing unauthenticated users to retrieve another user's in-progress upload when its temporary identifier is known. The identifier is high-entropy, is disclosed only to the uploader, and the file is removed on submission or by a scheduled cleanup, so a cross-user read is not achievable by guessing alone.8h CVE-2026-169546.5 MED

——0The AI Engine WordPress plugin before 3.6.4 does not redact secret configuration values before exposing them in an admin page's inline script data, allowing users with the Editor role to read the site's stored third-party API key and authentication tokens in cleartext, despite those secrets being restricted to administrators everywhere else.8h
