WooThemes Diarise through 1.5.9 contains a file read vulnerability that allows unauthenticated attackers to read arbitrary files through the calendar parameter of download.php. Attackers can send GET requests with file:// scheme paths to the calendar parameter to disclose sensitive files like /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.

SeaCMS through 8.7 contains an unauthenticated SQL injection vulnerability that allows remote attackers to manipulate database queries by injecting SQL through the rlist[] array parameter. Attackers can send GET requests to /comment/api/index.php with crafted rlist[] values using backtick-quoted variables and extractvalue to extract database information via error messages. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.

MetInfo CMS 6.0.0 before 6.1.1 contains a path traversal vulnerability in /include/thumb.php that allows unauthenticated attackers to read arbitrary files via the dir parameter. Attackers can send crafted requests with backslash sequences bypassing the str_replace filter to read files like config_db.php on Windows. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.

Intermesh Group-Office 3.3.0 before 3.5.5 contains an unauthenticated path traversal vulnerability in compress.php that allows remote attackers to read arbitrary files by manipulating the 'file' parameter. Attackers can send GET requests to /compress.php with '../' sequences in the 'file' parameter, which is appended to the cache path and passed to readfile(), to read files such as /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-21.

Discourse 1.9.0.beta2 before 1.9.0.beta13 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject scripts through the email parameter of /email/unsubscribed. Attackers can craft GET requests with SVG onload payloads, which unsubscribed.html.erb renders unescaped via html_safe, executing JavaScript in victims' browsers. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.

Broadstreet Ad Widget plugin for WordPress 2.2.0 before 2.12.0 contains a local file inclusion vulnerability that allows authenticated users to execute attacker-chosen PHP files by passing unsanitized input to require in views/modal/index.php. Attackers can supply directory traversal sequences in the 'step' parameter, optionally with a null byte, to include local files and execute PHP code. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.

QCubed 2.2.0 through 3.1.1 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject scripts through the installation_path parameter. Attackers can craft GET requests to /assets/php/_devtools/installer/step_2.php with malicious installation_path values echoed unescaped, executing JavaScript in victims' browsers. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-20.

Javo Spot theme for WordPress before 3.0.0 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files via the fn parameter of the jvfrm_spot_get_json AJAX action. Attackers can send GET requests to /wp-admin/admin-ajax.php with fn set to ../../wp-config.php to retrieve database credentials and secret keys. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.

webpack-dev-server is a development server that provides live reloading for webpack projects. In versions from 5.1.0 before 5.2.7 and in version 6.0.0, the unauthenticated open-editor endpoint validates the Host header with a regular expression meant for browser Origin schemes, so a Host value beginning with file: or with an extension scheme short-circuits the hostname and allowedHosts checks. A network peer that can reach the dev server can send a request with a malformed Host that passes validation and then causes the endpoint's URL construction to throw, and in the default non-production mode the server returns an HTTP 500 body containing the full exception stack trace, which discloses absolute filesystem paths, installed module locations, and internal source line numbers. The server keeps running, so there is no denial of service. The issue is fixed in webpack-dev-server 5.2.7 and 6.1.0, and users should upgrade to one of those versions or later.

webpack-dev-server is a development server that provides live reloading for webpack projects. In versions before 5.2.7 and in version 6.0.0, when a proxy entry is configured to forward WebSockets, the server forwards non-HMR WebSocket upgrade requests to the proxy target without validating the Host or Origin headers, so the allowedHosts protection does not apply to those proxied upgrades. A malicious web page visited by a developer can open a cross-origin WebSocket through the dev server and read from and write to the proxied backend, even when the server is bound to loopback. The issue is fixed in webpack-dev-server 5.2.7 and 6.1.0, where proxied WebSocket upgrades pass the same Host and Origin validation as the HMR WebSocket, and users should upgrade to one of those versions or later. As a workaround, omit WebSocket forwarding from proxy entries that do not need it and scope the proxy to specific paths.
