Vulnerabilidades

Con el objetivo de informar, advertir y ayudar a los profesionales sobre las últimas vulnerabilidades de seguridad en sistemas tecnológicos, ponemos a disposición de los usuarios interesados en esta información una base de datos con información en castellano sobre cada una de las últimas vulnerabilidades documentadas y conocidas.

Este repositorio con más de 75.000 registros esta basado en la información de NVD (National Vulnerability Database) – en función de un acuerdo de colaboración – por el cual desde INCIBE realizamos la traducción al castellano de la información incluida. En ocasiones este listado mostrará vulnerabilidades que aún no han sido traducidas debido a que se recogen en el transcurso del tiempo en el que el equipo de INCIBE realiza el proceso de traducción.

Se emplea el estándar de nomenclatura de vulnerabilidades CVE (Common Vulnerabilities and Exposures), con el fin de facilitar el intercambio de información entre diferentes bases de datos y herramientas. Cada una de las vulnerabilidades recogidas enlaza a diversas fuentes de información así como a parches disponibles o soluciones aportadas por los fabricantes y desarrolladores. Es posible realizar búsquedas avanzadas teniendo la opción de seleccionar diferentes criterios como el tipo de vulnerabilidad, fabricante, tipo de impacto entre otros, con el fin de acortar los resultados.

Mediante suscripción RSS o Boletines podemos estar informados diariamente de las últimas vulnerabilidades incorporadas al repositorio.

CVE-2026-73312

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains a refresh token replay vulnerability that allows attackers to reuse a refresh token multiple times by exploiting the failure to mark tokens as consumed when the parent access token has expired. Attackers can repeatedly submit the same refresh token to generate additional independent token pairs, achieving persistent unauthorized access for the token&#39;s full lifetime.

CVE-2026-73313

Fecha de publicación:

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains a multi-factor authentication bypass vulnerability in the passkey TFA provider that allows an authenticated attacker to complete login as another user by submitting their own registered passkey credential during the WebAuthn assertion step. The passkey verification path performs a global credential lookup without validating that the matched credential belongs to the user whose login is pending, enabling an attacker who knows a target account&#39;s password to sign the challenge with their own passkey and bypass multi-factor authentication on both public forum and ACP login paths.

CVE-2026-73315

Fecha de publicación:

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains a server-side request forgery vulnerability in the PayPal REST webhook handler that allows unauthenticated attackers to cause the server to make outbound HTTP requests to arbitrary destinations by supplying a crafted certificate URL in webhook headers without scheme, hostname, or allowlist validation. Attackers can submit a crafted POST to the PayPal webhook callback endpoint to reach internal network resources including cloud instance metadata services, potentially disclosing IAM credentials or enabling secondary internal service exploitation.

CVE-2026-73311

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains an OAuth2 authorization code reuse vulnerability that allows attackers to obtain unauthorized token pairs by submitting a previously used authorization code. Attackers can exploit the failure to invalidate or mark authorization codes as consumed after initial token issuance to receive an independent token pair for the same user and scopes, bypassing the single-use guarantee of the OAuth2 authorization code flow.

CVE-2026-73314

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains a signature verification logic error in the PayPal REST webhook handler that allows unauthenticated attackers to bypass payment signature validation by submitting a webhook request with an unsupported auth_algo header value. When the algorithm cannot be mapped to a supported hash function, the verification function incorrectly returns true instead of failing, causing the caller to treat the fabricated request as verified and process the payment event without a valid PayPal signature.

CVE-2026-73316

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains a payment replay vulnerability in the PayPal REST payment provider that allows attackers to process the same webhook payload multiple times by exploiting a missing duplicate transaction ID check. Attackers can replay a valid webhook payload to trigger duplicate payment events, resulting in repeated subscription activations and unauthorized account upgrades.

CVE-2026-73309

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** XenForo before 2.3.13 contains an authentication bypass vulnerability in the OAuth2 token endpoint that allows unauthenticated attackers to obtain valid token pairs by submitting empty values for client_secret and code_verifier parameters. Attackers can exploit PHP truthy evaluation logic, which treats empty strings as false and skips client secret validation and PKCE code verifier validation, to exchange a valid authorization code for a token pair without proving client identity or holding the PKCE commitment.

CVE-2026-33387

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** A template injection vulnerability was discovered in the Dashboards functionality due to improper validation of an input parameter. An authenticated user with the required privileges can define a dashboard containing a malicious payload, or a victim can be socially engineered into importing a malicious dashboard. When the victim views or imports the dashboard, the payload executes in their browser context, allowing the attacker to modify application data or disrupt application availability.

CVE-2026-33388

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** An access control vulnerability was discovered in the Credentials Manager functionality due to insufficient validation of user privileges. A remote authenticated user with limited privileges can view a limited subset of the available entries in the Credentials Manager. The actual credential values are not directly visible, but the user can delete entries or edit their properties. An attacker who deletes or edits an entry can disrupt authentication for dependent devices, and one who manipulates an entry&#39;s configuration may be able to indirectly obtain the credentials.

CVE-2026-33389

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** An improper certificate/host key validation vulnerability was discovered in the Smart Polling functionality, which established encrypted connections to target devices without validating the remote host&#39;s identity, and no option was provided to enable it. A man-in-the-middle attacker positioned between a sensor and a polled device can, during a polling session, impersonate the device and intercept the communication, including the credentials used to access it. The captured credentials can then be replayed to authenticate against the device itself or against other devices sharing the same credentials, allowing the attacker to access and tamper with the device&#39;s data and to disrupt its operations.

CVE-2026-33391

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** An access control vulnerability was discovered in the Smart Polling configuration functionality due to insufficient validation of user privileges. An authenticated user with limited privileges can remotely bypass the intended access control of the web management interface and modify the Smart Polling discovery configuration. This allows the attacker to disrupt the visibility of assets in the monitored network.

CVE-2026-33920

Fecha de publicación:

08/09/2026

Idioma:

Inglés

*** Pendiente de traducción *** A cross-site request forgery vulnerability was discovered in the login functionality (both standard and SAML) due to missing validation of the anti-CSRF token. An attacker with a valid account can trick a victim into unknowingly authenticating with the attacker&#39;s credentials. Any operation performed by the victim in this state is attributed to the attacker&#39;s account, compromising the integrity of the audit trail.
