An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41872 in the wild and no public exploit code.\n\nAffected product: EPG, Inc. \"Kura Sushi Official App\" for Android. 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-2026-41872/ (Markdown: https://insights.sbomify.com/CVE-2026-41872/index.md)","id":"CVE-2026-41872","markdown":"https://insights.sbomify.com/CVE-2026-41872/index.md","name":"CVE-2026-41872","record":{"aliases":["GHSA-mcjh-pcfv-25rh"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Kura Sushi Official App","requires_auth":"none","summary":"Improper certificate validation in the Kura Sushi app allows man-in-the-middle attackers to intercept or alter push notification traffic.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"\"Kura Sushi Official App\" provided by EPG, Inc. is vulnerable to improper certificate validation.
