CVE-2026-71269

CVE-2026-71269 affects Node-RED’s local-filesystem library storage module (getLibraryEntry() and saveLibraryEntry() in packages/node_modules/@node-red/runtime/lib/storage/localfilesystem/library.js). The vulnerability arises because GET/POST requests to /library/:lib/:type/*path join the user-sup...

CVE-2026-71268

OpenPLC Runtime v3 is affected by a path traversal in compile_program() (webserver/openplc.py): it processes directives of the form (FILE:path content ) and writes to os.path.join('./core', file_path) without validating that file_path stays under ./core. A crafted ST file like (FILE:../../../etc/...

CVE-2026-71264 WLED Unauthenticated Configuration Disclosure via /json/cfg and Global Settings-PIN Lock State

WLED's GET /json/cfg endpoint registered in wled00/wledserver.cpp calls serveJson with no settings-PIN check, unlike the /edit endpoint which explicitly checks correctPIN, disclosing the device's general configuration network, hardware, LED setup to any unauthenticated client on the network...

tar: tar: --one-top-level hardlink targets not confined to top-level directory enabling arbitrary file overwrite

A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary...
