2DescriptionGitHub Advisory
Meshtastic is an open source mesh networking solution. In versions from 2.5.0 to before 2.6.11, the flashing procedure of several hardware vendors was resulting in duplicated public/private keys. Additionally, the Meshtastic was failing to properly initialize the internal randomness pool on some platforms, leading to possible low-entropy key generation. When users with an affected key pair sent Direct Messages, those message could be captured and decrypted by an attacker that has compiled the list of compromised keys. This issue has been patched in version 2.6.11 where key generation is delayed til the first time the LoRa region is set, along with warning users when a compromised key is detected. Version 2.6.12 furthers this patch by automatically wiping known compromised keys when found. A workaround to this vulnerability involves users doing a complete device wipe to remove vendor-cloned keys.
Executive ViewAI
Meshtastic devices running versions 2.5.0 through 2.6.10 contain duplicated cryptographic keys due to manufacturing flaws and weak entropy initialization, potentially allowing attackers to decrypt direct messages if they obtain the compromised key list. Organizations deploying Meshtastic for sensitive communications must immediately assess their device inventory and prioritize upgrades to prevent unauthorized message interception.
Apply vendor patch. If immediate patching is unavailable: (1) perform complete device wipes to remove vendor-cloned keys; (2) restrict Meshtastic use to non-sensitive communications until patched; (3) monitor for detection of compromised keys using version 2.6.11 or later warning mechanisms; (4) implement network segmentation to limit Meshtastic mesh exposure to critical systems.
