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-2026-53536

*** Pendiente de traducción *** Activepieces is an open source AI workflow automation platform. Prior to 0.83.0, the /v1/step-files/signed download endpoint verified the supplied JWT against the shared signing secret but did not check the token's audience, and combined with a missing null-check on the decoded fileId, this allowed any caller holding any valid Activepieces JWT (including a freshly created user's own access token) to receive a step-file belonging to another tenant. The file returned was whatever PostgreSQL happened to scan first for type = FLOW_STEP_FILE, varying over time as the database changed, so an authenticated user could obtain step-file attachments belonging to other tenants on the same instance; the attacker could not target a specific victim or file, and the access was read-only with no integrity or availability impact. This issue is fixed in version 0.83.0.

CVE-2026-47085

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. URLAUTH token forgery can occur via a missing mboxkey. If an attacker knew a folder name on the victim's account for which the victim had never issued an auth URL, they could forge a working URLAUTH token by computing an HMAC-SHA1 value with a predictable key, giving them read access to the mailbox. (URLAUTH is an obscure feature, meaning that the odds of any user actually being susceptible to this attack are very low. Perhaps no public clients use URLAUTH.)

CVE-2026-47086

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. GENURLAUTH-issued tokens can bypass ACLs. Any authenticated user could mint a URLAUTH token (via the GENURLAUTH command) for any mailbox they could name, even without read access on it. This would allow reading mail from mailboxes despite having no granted permissions.

*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. URLAUTH does not honor revoked authorizer access. A URLAUTH URL minted while the authorizer had access continued to work after that access was revoked.

Idioma:
Inglés
*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is heap exposure in nested MIME comment parsing. An authenticated IMAP user could craft an email message containing an RFC 822 comment ending with a backslash. When parsing the message, the server would read past the message's end in memory, and read into the heap, returning the read content to the user.

*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. LISTRIGHTS os not limited to users with admin access. An authenticated user could call IMAP LISTRIGHTS against any mailbox they could name and learn what principals had what access to it. (This action should have been restricted to users with admin access on the target mailbox.)

CVE-2026-47081

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is an XAPPLEPUSHSERVICE folder existence oracle and push hijack. An authenticated IMAP user could probe for the existence of arbitrary mailboxes on other users' accounts via the XAPPLEPUSHSERVICE command and then create Apple Push Notification Service notifications for new mail in those mailboxes to their own APNS device. This did not leak any data about the content of mailboxes. Instead, a "mailbox has changed" notice would be pushed when the mailbox modseq changed.

*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. The vacation "fcc" feature skips the destination-mailbox ACL. A user whose vacation Sieve script used :fcc (to save a copy of the sent message) could deliver vacation auto-reply copies into any mailbox the script could name, regardless of whether the script owner had insert permissions on the destination mailbox.

Idioma:

*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. There is an ESEARCH cross-user content oracle. By using the ESEARCH command, an authenticated IMAP user could enumerate folder names under any account they could name. Search would return UIDs of messages matching the search, creating a content oracle (without allowing arbitrary reads of the target's content).

*** Pendiente de traducción *** An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. The LOCALDELETE command bypassed ACL checks. An authenticated but non-admin user could invoke the admin-only LOCALDELETE IMAP command and delete mailboxes for which they had no permissions.

CVE-2026-46513

Fecha de publicación:

Idioma:
Inglés
*** Pendiente de traducción *** Frogman provides headless PBX control through MCP and HTTP API. Prior to 1.6.2, Frogman stored API tokens generated by Tools/CreateApiToken.php:33-36 as raw bin2hex(random_bytes(32)) strings in oc_api_tokens, and Frogman.class.php:78 authenticated the X-Frogman-Token header by comparing it with the stored raw value, allowing database read access to recover reusable active tokens at their assigned permission level, including admin. This issue is fixed in version 1.6.2.

Idioma:

*** Pendiente de traducción *** Frogman provides headless PBX control through MCP and HTTP API. Prior to 1.6.2, fm_reset_password in Tools/ResetPassword.php:48-53 returned a plaintext password and fm_add_extension in Tools/AddExtension.php:172 returned a plaintext secret; Frogman.class.php:2207-2211 used auditOutcome to JSON-encode those responses into oc_audit_log.detail, allowing any PERM_READ caller with access to fm_audit_search to recover the stored credentials. This issue is fixed in version 1.6.2.
