Description

Leantime 3.6.2 contains an open redirect vulnerability in the Login controller that allows unauthenticated attackers to redirect authenticated users to arbitrary external sites by manipulating the redirectUrl POST parameter. Attackers can craft a malicious login URL with a tampered redirectUrl value that bypasses FILTER_SANITIZE_URL validation to redirect victims to attacker-controlled sites for phishing or credential theft.

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.
