Hereta ETH-IMC408M, published on 16 Mar 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-29521 in the wild and no public exploit code.\n\nAffected product: Shenzhen Hereta Technology Co., Ltd. Hereta ETH-IMC408M. 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-2026-29521/ (Markdown: https://insights.sbomify.com/CVE-2026-29521/index.md)","id":"CVE-2026-29521","markdown":"https://insights.sbomify.com/CVE-2026-29521/index.md","name":"CVE-2026-29521","record":{"aliases":["GHSA-3cmm-8xw2-c67r"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Media Converter","requires_auth":"none","summary":"Attackers can modify device configuration, including network settings and RADIUS accounts, by tricking users into visiting malicious pages.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"eth-imc408m_firmware","vendor":"hereta"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Hereta ETH-IMC408M firmware version 1.0.15 and prior contain a cross-site request forgery vulnerability that allows attackers to modify device configuration by exploiting missing CSRF protections in setup.cgi.
