An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-55292 exists.\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-2025-55292/ (Markdown: https://insights.sbomify.com/CVE-2025-55292/index.md)","id":"CVE-2025-55292","markdown":"https://insights.sbomify.com/CVE-2025-55292/index.md","name":"CVE-2025-55292","record":{"aliases":["GHSA-45vg-3f35-7ch2"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Meshtastic mesh firmware","requires_auth":"none","summary":"Attackers can spoof HAM mode to bypass encryption and modify node details in Meshtastic mesh networks, requiring firmware updates.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"meshtastic_firmware","vendor":"meshtastic"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-348","name":"Use of Less Trusted Source"}],"description":"Meshtastic is an open source mesh networking solution. In the current Meshtastic architecture, a Node is identified by their NodeID, generated from the MAC address, rather than their public key. This aspect downgrades the security, specifically by abusing the HAM mode which doesn't use encryption. An attacker can, as such, forge a NodeInfo on behalf of a victim node advertising that the HAM mode is enabled. This, in turn, will allow the other nodes on the mesh to accept the new information and overwriting the NodeDB. The other nodes will then only be able to send direct messages to the victim by using the shared channel key instead of the PKC. Additionally, because HAM mode by design doesn't provide any confidentiality or authentication of information, the attacker could potentially also be able to change the Node details, like the full name, short code, etc. To keep the attack persistent, it is enough to regularly resend the forged NodeInfo, in particular right after the victim sends their own. A patch is available in version 2.7.6.834c3c5.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"In Meshtastic, an attacker can spoof licensed amateur flag for a node","id":"CVE-2025-55292","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Meshtastic allows crafting of specific NodeInfo packets that overwrite any publicKey saved in the NodeDB","id":"CVE-2025-55293"},"packages":[],"prev":{"headline":"Shaarli allows reflected XSS via searchtags parameter","id":"CVE-2025-55291"},"products":["firmware"],"published":"2026-01-27","related":[{"cvss_score":9.5,"headline":"Meshtastic Repeated Public and Private Keypairs","id":"CVE-2025-52464","kev_date_added":null,"published":"2025-06-19"},{"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":8.1,"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)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-28","vendors":["meshtastic"]},"summary":"Attackers can spoof HAM mode to bypass encryption and modify node details in Meshtastic mesh networks, requiring firmware updates.","url":"https://insights.sbomify.com/CVE-2025-55292/"}
