It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-15315 and fix it if it is affected.\n\nWhat it is: CVE-2026-15315 is a high-severity authentication bypass vulnerability in TP-Link Systems Inc Tapo C120 v1, published on 18 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-15315 in the wild and no public exploit code.\n\nAffected product: TP-Link Systems Inc Tapo C120 v1. 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-2026-15315/ (Markdown: https://insights.sbomify.com/CVE-2026-15315/index.md)","id":"CVE-2026-15315","markdown":"https://insights.sbomify.com/CVE-2026-15315/index.md","name":"CVE-2026-15315","record":{"aliases":["GHSA-xw5g-644p-8357"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TP-Link Tapo camera","requires_auth":"none","summary":"An attacker on the local network can bypass authentication to gain administrative access and cause denial of service on TP-Link Tapo cameras.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TPLink","cpe":[{"product":"tapo_c120_firmware","vendor":"tp-link"},{"product":"tapo_c200_firmware","vendor":"tp-link"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Tapo C120 v1 and C200 v5\ncontain an improper authentication vulnerability within the login\nauthentication verification module.
