An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-52464 in the wild and no public exploit code.\n\nAffected product: meshtastic firmware. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-52464/ (Markdown: https://insights.sbomify.com/CVE-2025-52464/index.md)","id":"CVE-2025-52464","markdown":"https://insights.sbomify.com/CVE-2025-52464/index.md","name":"CVE-2025-52464","record":{"aliases":["CVE-2025-54797","GHSA-gq7v-jr8c-mfr7"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Meshtastic mesh firmware","requires_auth":"none","summary":"Attackers can decrypt private messages if devices use duplicated or low-entropy keys due to flawed initialization or vendor flashing.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"meshtastic_firmware","vendor":"meshtastic"}],"cvss":{"score":9.5,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:L/SI:L/SA:H","version":"4.0"},"cwes":[{"id":"CWE-331","name":"Insufficient Entropy"}],"description":"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-06","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-06T21:12:34Z","kind":"github_poc","ref":"https://github.com/msdmehdipour/meshtastic-cve-2025-52464-poc","stars":1,"title":"Software-only proof of concept for CVE-2025-52464 in Meshtastic Direct Messages"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Meshtastic Repeated Public and Private Keypairs","id":"CVE-2025-52464","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"GeoServer has an arbitrary file write vulnerability in its Master Password Dump Page","id":"CVE-2025-52465"},"packages":[],"prev":{"headline":"Cross-site request forgery in Active! mail 6","id":"CVE-2025-52463"},"products":["firmware"],"published":"2025-06-19","related":[{"cvss_score":9.4,"headline":"Meshtastic allows crafting of specific NodeInfo packets that overwrite any publicKey saved in the NodeDB","id":"CVE-2025-55293","kev_date_added":null,"published":"2025-08-18"},{"cvss_score":9.4,"headline":"Meshtastic incorrectly hands malformed packets leads to controlled buffer overflow","id":"CVE-2025-24797","kev_date_added":null,"published":"2025-04-14"},{"cvss_score":8.2,"headline":"In Meshtastic, an attacker can spoof licensed amateur flag for a node","id":"CVE-2025-55292","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":8.1,"headline":"Meshtastic firmware Authentication/Authorization Bypass via MQTT","id":"CVE-2024-47078","kev_date_added":null,"published":"2024-09-25"},{"cvss_score":7.5,"headline":"Meshtastic: Malformed UTF-8 in User.long_name broadcast over LoRa causes mesh-wide client decode failure","id":"CVE-2026-42566","kev_date_added":null,"published":"2026-07-19"},{"cvss_score":7.5,"headline":"Device crash via malformed MQTT packet when downlink is enabled in Meshtastic device firmware","id":"CVE-2024-45038","kev_date_added":null,"published":"2024-08-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-23","vendors":["meshtastic"]},"summary":"Attackers can decrypt private messages if devices use duplicated or low-entropy keys due to flawed initialization or vendor flashing.","url":"https://insights.sbomify.com/CVE-2025-52464/"}
