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-2026-6559 in the wild and no public exploit code.\n\nAffected product: Wavlink WL-WN579A3. 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-2026-6559/ (Markdown: https://insights.sbomify.com/CVE-2026-6559/index.md)","id":"CVE-2026-6559","markdown":"https://insights.sbomify.com/CVE-2026-6559/index.md","name":"CVE-2026-6559","record":{"aliases":["GHSA-x8cm-r99c-gv26"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Wavlink router","requires_auth":"none","summary":"Remote attackers can execute arbitrary scripts via the Hostname parameter in the login interface of Wavlink WL-WN579A3 routers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A weakness has been identified in Wavlink WL-WN579A3 220323.
