CVE-2025-52464

26
FAUCET Score

CVE-2025-52464 is a high-severity vulnerability affecting Meshtastic firmware versions 2.5.0 through 2.6.10, stemming from duplicated public/private keys during flashing and insufficient randomness for key generation on some platforms. This flaw allows an attacker to decrypt Direct Messages if they have compiled a list of compromised keys, with a CVSS score of 8.3. While no active exploitation, public exploit code, or significant community discussion has been observed, the vulnerability has a FAUCET Risk Score of 80/100. Patches in versions 2.6.11 and 2.6.12 address this by delaying key generation, warning users of compromised keys, and automatically wiping them.
