Security Vulnerabilities - CVEs Published In April 2026
A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure.

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.

Synway SMG Gateway Management Software contains an OS command injection vulnerability in the RADIUS configuration endpoint at /en/9-2radius.php where the radius_address POST parameter is split and interpolated directly into a sed command without sanitization. An unauthenticated remote attacker can inject arbitrary shell commands by submitting a POST request with crafted radius_address, radius_address2, shared_secret2, source_ip, timeout, or retry parameters along with save=1 and enable_radius=1 to achieve remote code execution. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-07-11 (UTC).

U-SPEED N300 router V1.0.0 does not implement rate limiting or account lockout protections on the /api/login endpoint. This allows an attacker on the local network to perform unlimited authentication attempts, enabling brute-force attacks against the administrator account and potential unauthorized access to the router management interface.

When Keycloak is started with `--features-disabled=account,account-api`, the Account REST API is only partially disabled. Five endpoints under the versioned path `/account/v1alpha1` remain fully functional — including both read and write operations — because they lack the `checkAccountApiEnabled()` gate that correctly blocks four other endpoints in the same REST service class. The user needs to have permissions to use the API.

A Cross-Site Request Forgery (CSRF) vulnerability exists in the web management interface of the Dbit N300 T1 Pro wireless router V1.0.0. The router fails to implement proper CSRF protection mechanisms such as anti-CSRF tokens or strict Origin/Referer validation for administrative API endpoints. An attacker can craft a malicious webpage that sends forged HTTP requests to configuration endpoints such as /api/setWlan. If an authenticated administrator visits the malicious webpage, the victim's browser automatically includes the valid session cookie in the request, allowing the router to process the request as a legitimate administrative action.
