Hot Pepper Gourmet App, published on 27 Apr 2021. 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-2021-20715 in the wild and no public exploit code.\n\nAffected product: Recruit Co., Ltd. Hot Pepper Gourmet App. 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-2021-20715/ (Markdown: https://insights.sbomify.com/CVE-2021-20715/index.md)","id":"CVE-2021-20715","markdown":"https://insights.sbomify.com/CVE-2021-20715/index.md","name":"CVE-2021-20715","record":{"aliases":["GHSA-h9hq-cmw2-pxgh"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Hot Pepper Gourmet App","requires_auth":"none","summary":"A remote attacker can trick users into visiting arbitrary websites via the Hot Pepper Gourmet mobile app due to improper access control.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"hot_pepper_gourmet","vendor":"recruit-holdings"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Improper access control vulnerability in Hot Pepper Gourmet App for Android ver.4.111.0 and earlier, and for iOS ver.4.111.0 and earlier allows a remote attacker to lead a user to access an arbitrary website via the vulnerable App.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Open redirect in Hot Pepper Gourmet App","id":"CVE-2021-20715","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in Buffalo network devices","id":"CVE-2021-20716"},"packages":[],"prev":{"headline":"Path traversal in WP Fastest Cache","id":"CVE-2021-20714"},"products":["Hot Pepper Gourmet App"],"published":"2021-04-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Recruit Co., Ltd."]},"summary":"A remote attacker can trick users into visiting arbitrary websites via the Hot Pepper Gourmet mobile app due to improper access control.","url":"https://insights.sbomify.com/CVE-2021-20715/"}
