CVE-2026-72588
A user enumeration vulnerability in bluewave-labs/Checkmate through 2.1.0 allows an unauthenticated remote attacker to determine whether a given email address is registered. The POST /api/v1/auth/recovery/request endpoint returns HTTP 200 for registered email addresses and a different status code for unregistered ones, enabling attackers to enumerate valid user accounts.

CVE-2026-72587
A cache poisoning vulnerability in CoreBunch/Instatic through 0.0.14 allows an unauthenticated remote attacker to poison the shared process-wide render cache by manipulating the u query parameter of the GET /_instatic/hole/<nodeId> server island endpoint. The originating-page URL supplied in u seeds the route template frame used for rendering, and the result is stored in a shared cache keyed only on nodeId, enabling an attacker to inject a crafted route that causes all subsequent visitors to receive malformed or attacker-controlled fragment content.

CVE-2026-72585
An authorization bypass vulnerability in Grafana through 13.2.0 allows an Editor-role user to delete protected contact points (receivers) without the required alert.notifications.receivers.protected:write permission. The fix for CVE-2026-21724 addressed only the UPDATE code path in both pkg/services/ngalert/provisioning/contactpoints.go and pkg/services/ngalert/notifier/receiver_svc.go, but the DELETE path in both receiver services was not updated with the protected-field check, leaving deletion operations unguarded.

CVE-2026-72583
A 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.

CVE-2026-72576
A 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.
