Technical description

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Desktop for Windows omits publisherName from packages/app-desktop/package.json, so the generated app-update.yml causes NsisUpdater.verifySignature() to skip comparison of a downloaded update's Authenticode signer with Joplin's signer. An attacker who controls the update delivery path can replace the update metadata and installer, and the client accepts an installer signed by another publisher or left unsigned after the user approves installation. Successful exploitation runs attacker-controlled code with the user's privileges and can compromise notes, credentials, and local data. This issue is fixed in version 3.7.2.

——3A vulnerability was identified in spatie Scotty up to 1.4.2. Affected is the function SelfUpdater::update of the file app/Updater/SelfUpdater.php of the component Self Update Handler. Such manipulation leads to download of code without integrity check. It is possible to launch the attack remotely. Upgrading to version 1.4.3 is able to address this issue. The name of the patch is 4b4e11bfc98e3a2159bb2b3d9b040293fcc44744. It is advisable to upgrade the affected component.4d CVE-2026-634055.9 MED

——2AnyCable is a realtime server for reliable two-way communication that supports any backend. Prior to 1.6.15, the Pusher-compatible REST API in pusher/http.go includes the caller-supplied body_md5 value in the HMAC input but does not calculate the digest of the received request body or compare it with the signed value. An attacker who obtains a legitimate signed POST request can retain its query parameters and auth_signature while replacing the body, causing Handler and handleEvents to accept and broadcast attacker-selected event content. The absence of an auth_timestamp freshness check also allows the captured signature to be replayed indefinitely. This can forge server-side events, modify application state, or deliver attacker-controlled messages to WebSocket clients within the signed request's application context. This issue is fixed in version 1.6.15.4d CVE-2026-70067.3 HIG

——0Sublime Text for Windows through Build 4192 (Sublime Text 4) and Build 3207 (Sublime Text 3) contains a local privilege escalation vulnerability that allows unprivileged local attackers to execute arbitrary code with elevated privileges by abusing the update staging mechanism. Attackers can place a malicious DLL in the user-writable staging directory under %LOCALAPPDATA%, mark it read-only to bypass cleanup, and have the elevated installer copy it into the protected installation directory, causing the DLL to execute in the context of any higher-privileged user who subsequently launches the application.4d CVE-2026-6287410.0 CRI
