Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19745 in the wild and no public exploit code.\n\nAffected product: Calix GigaSpire. 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-2026-19745/ (Markdown: https://insights.sbomify.com/CVE-2026-19745/index.md)","id":"CVE-2026-19745","markdown":"https://insights.sbomify.com/CVE-2026-19745/index.md","name":"CVE-2026-19745","record":{"aliases":["GHSA-693x-w4h4-3ppc"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Calix GigaSpire router","requires_auth":"low_privilege","summary":"Remote attackers may cause denial of service in Calix GigaSpire web management via sessionKey manipulation, though vendor disputes impact.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"A flaw has been found in Calix GigaSpire 26.1.0.

The existence of this vulnerability is still disputed at present. The vendor explains: \"We reproduced the reported request pattern.
