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-2026-36609 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2026-36609/ (Markdown: https://insights.sbomify.com/CVE-2026-36609/index.md)","id":"CVE-2026-36609","markdown":"https://insights.sbomify.com/CVE-2026-36609/index.md","name":"CVE-2026-36609","record":{"aliases":["GHSA-wmgq-9q82-422r"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Mercusys AC12G router","requires_auth":"none","summary":"An attacker can recover plaintext passwords by exploiting static nonces and weak XOR encoding in Mercusys AC12G routers.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-341","name":"Predictable from Observable State"},{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Mercusys AC12G (EU) V1 router with firmware AC12G(EU)_V1_200909 uses a static authentication nonce that does not change between requests from the same source IP.
