Descripción técnica

The Webpushr Push Notifications plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'webpushr_notification_title' and 'webpushr_notification_body' parameters in versions up to, and including, 4.39.0. This is due to insufficient input sanitization in the save_send_notification_flag() function and missing output escaping in the wpp_notification_box() function, which concatenates raw post meta values directly into HTML attribute and textarea contexts. 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.

——0A stored cross-site scripting (XSS) vulnerability in lobehub/lobe-chat through v2.2.13 allows a low-privileged authenticated user to inject arbitrary JavaScript into the application by uploading a crafted SVG file as a user avatar. The avatar upload handler derives the stored file extension and S3 content type from the original filename rather than inspecting file content, enabling an attacker to store an SVG containing a script element that executes in the browser of any user who views the attacker's profile or avatar.2h CVE-2026-725835.4 MED

——0A stored cross-site scripting (XSS) vulnerability in fastschema through v0.15.1 allows a low-privileged authenticated user to upload an SVG file containing malicious JavaScript by bypassing the MIME type allow-list check. The pkg/rclonefs/base.go PutMultipart function validates the Content-Type header supplied by the client rather than inspecting the actual file content, enabling an attacker to rename a file to .jpg while specifying image/svg+xml to bypass the filter and store a script-bearing SVG in the web root.2h CVE-2026-725765.4 MED

——0A stored cross-site scripting (XSS) vulnerability in Bludit 4.0.0-beta allows a low-privileged authenticated user (Author role) to inject arbitrary JavaScript by uploading a crafted SVG file as the site logo. The /admin/ajax/logo-upload endpoint in bl-kernel/ajax/logo-upload.php moves the uploaded file directly to the web root via Filesystem::mv() without invoking sanitizeSVG() or transformImage(), while SVG is present in the ALLOWED_IMG_EXTENSION and ALLOWED_IMG_MIMETYPES allow-lists. A stored script tag in the SVG executes in the browser of any user who loads the logo.2h CVE-2026-725705.4 MED

——0A stored cross-site scripting (XSS) vulnerability in cube-root/directory-serve through 1.3.7 allows an attacker to inject arbitrary JavaScript into the web interface by uploading a file with a crafted filename containing HTML attribute-breaking characters. The lib/helper/html.js file does not sanitize filenames before embedding them in HTML templates at line 28, enabling script execution in other users' browsers when they view the file listing.2h CVE-2026-572796.8 MED
