Archer C7 v5, published on 27 Oct 2026. \nExploitation: There is no known exploitation of CVE-2026-102812 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc. Archer C7 v5. 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-2026-102812/ (Markdown: https://insights.sbomify.com/CVE-2026-102812/index.md)","id":"CVE-2026-102812","markdown":"https://insights.sbomify.com/CVE-2026-102812/index.md","name":"CVE-2026-102812","record":{"aliases":["GHSA-xgv8-3vj8-53q7"],"analysis":null,"analysis_generated_by":null,"assigner":"TPLink","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"A hard-coded\ncryptographic key vulnerability exists in the user-configuration backup\nmechanism of TP-Link RE305 V3 and Archer C7 V5.
