CVE-2026-12938

*** Pendiente de traducción *** The Newsletters Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;target&#39; attribute of the [newsletters_post] shortcode in versions up to and including 4.15. This is due to insufficient input sanitization and output escaping in the posts_single() function which propagates the attacker-controlled &#39;target&#39; attribute into the global $wpml_target, and in the shortcode_posts() &#39;post_thumbnail&#39; handler which concatenates $wpml_target into a target="..." HTML attribute without esc_attr(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

*** Pendiente de traducción *** The Wholesale for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.0.5. This is due to the `save_requests_meta()` function applying only `sanitize_text_field()` to the `user_role_set` POST parameter before passing it directly to `WP_User::add_role()`, with no allowlist validation against permitted wholesale roles and no capability check such as `current_user_can(&#39;promote_users&#39;)` or `current_user_can(&#39;manage_options&#39;)`. This makes it possible for authenticated attackers with author-level access and above to escalate their privileges to administrator by supplying `administrator` as the `user_role_set` value in a crafted request. The function is gated only by a nonce (`request_user_role_nonce`) that is rendered in the meta box on the `wwp_requests` post edit screen; because the post type is registered with `capability_type => &#39;post&#39;`, any author-level user who has authored a `wwp_requests` post — such as one created via the wholesale registration form — can access this nonce and submit the role-assignment request.

CVE-2026-56822

Fecha de publicación:

29/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the OcspServerCertificateValidator forwards the SslHandshakeCompletionEvent before the asynchronous OCSP validation completes. This allows the client&#39;s downstream handlers to send sensitive application data (e.g., HTTP requests) to a revoked server before the channel is closed by the OCSP check. n io.netty.handler.ssl.ocsp.OcspServerCertificateValidator#userEventTriggered, when an SslHandshakeCompletionEvent is received, the validator immediately calls ctx.fireUserEventTriggered(evt). It then initiates an asynchronous OCSP query using OcspClient.query. Because the handshake completion event is forwarded immediately, downstream handlers in the client&#39;s pipeline are notified that the TLS handshake is successful. They may then begin reading and processing incoming application data or sending outgoing data. If the OCSP response later indicates the server&#39;s certificate is REVOKED, the validator closes the channel, but by this time, the client may have already leaked sensitive data to a revoked server or processed malicious responses from it. This issue has been fixed in versions 4.1.136.Final and 4.2.16.Final.

*** Pendiente de traducción *** Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the OcspServerCertificateValidator flags an out-of-date OCSP response but does not stop processing it, so an expired GOOD response is still reported as VALID, letting an on-path attacker replay a stale GOOD response to bypass revocation of a since-revoked certificate. Exploitation can lead to certificate revocation bypass via replay of an expired OCSP response. Any application using OcspServerCertificateValidator is affected; a revoked certificate can be accepted. This issue has been fixed in versions 4.1.136.Final and 4.2.16.Final.

*** Pendiente de traducción *** goshs is a feature-rich single-binary file server for red teamers and developers. From 2.1.3 until 2.1.4, the sftpserver/sftpserver.go password handler used Username != "" && Password != "", so running goshs with -b &#39;admin:&#39; -sftp and no -fkf left both SFTP authentication handlers unset and allowed unauthenticated file access. This issue is fixed in version 2.1.4.

*** Pendiente de traducción *** goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.4, the httpserver/server.go wdGuard handled WebDAV MOVE as a write-only method and did not enforce --no-delete, allowing WebDAV clients to delete or overwrite files via MOVE with Overwrite: T. This issue is fixed in version 2.1.4.

*** Pendiente de traducción *** goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.5, the httpserver/handler.go sendFile handler opened files using a cleaned path but derived the authorization filename from raw req.URL.Path, so a trailing slash could bypass .goshs ACL-file protection and block-list checks. This issue is fixed in version 2.1.5.

*** Pendiente de traducción *** goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.5, the httpserver/updown.go multipart upload handler split part.FileName() on / but did not reject .., allowing an unauthenticated upload with filename .. to create a file outside the served tree. This issue is fixed in version 2.1.5.

*** Pendiente de traducción *** Pagy is agnostic pagination in plain Ruby. From 43.0.0 until 43.5.6, Pagy::I18n.locale= in gem/lib/pagy/modules/i18n/i18n.rb stored locale values verbatim and later used them as .yml path components, allowing untrusted params[:locale] values with absolute paths or ../ sequences to create a file existence and readability oracle for YAML files. This issue is fixed in version 43.5.6.

*** Pendiente de traducción *** goshs is a feature-rich single-binary file server for red teamers and developers. Prior to 2.1.1, the httpserver/updown.go bulkDownload handler for ?bulk&file= ZIP downloads did not call findEffectiveACL or applyCustomAuth, allowing unauthenticated reads of files protected only by .goshs folder ACLs and block lists. This issue is fixed in version 2.1.1. This vulnerability exists due to an incomplete fix for CVE-2026-40189.

CVE-2026-59921

Fecha de publicación:

28/07/2026

Idioma:

Inglés

*** Pendiente de traducción *** Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, HttpPostRequestEncoder constructs multipart HTTP request bodies by directly concatenating user-supplied filenames and field names into Content-Disposition MIME headers without validating or sanitizing CRLF characters (\r\n). Since MIME headers are delimited by CRLF, an attacker who controls the filename can inject arbitrary MIME headers into the multipart body part. The root cause is that neither the encoder nor the FileUpload implementations&#39; setFilename() methods, which only check for null, neutralize CRLF characters before the filename is embedded into the header. This issue has been fixed in versions 4.1.136.Final and 4.2.16.Final.

*** Pendiente de traducción *** gotd/td is a T Telegram MTProto API client in Go. Prior to 0.145.1, proto.UnencryptedMessage.Decode in proto/unencrypted_message.go read attacker controlled dataLen from an unauthenticated MTProto unencrypted packet and allocated make([]byte, dataLen) before checking the remaining buffer, allowing remote unauthenticated denial of service through excessive memory allocation and CPU or garbage collection pressure. This issue is fixed in version 0.145.1.
