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-2024-23388 in the wild and no public exploit code.\n\nAffected product: Mercari, Inc. \"Mercari\" 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-2024-23388/ (Markdown: https://insights.sbomify.com/CVE-2024-23388/index.md)","id":"CVE-2024-23388","markdown":"https://insights.sbomify.com/CVE-2024-23388/index.md","name":"CVE-2024-23388","record":{"aliases":["GHSA-xx65-34vr-mqrj"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Mercari Android app","requires_auth":"none","summary":"A remote attacker can redirect users to arbitrary websites via a custom URL scheme, facilitating phishing attacks against Mercari Android app users.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"mercari","vendor":"mercari"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Improper authorization in handler for custom URL scheme issue in \"Mercari\" App for Android prior to version 5.78.0 allows a remote attacker to lead a user to access an arbitrary website via the vulnerable App. As a result, the user may become a victim of a phishing attack.","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 \"Mercari\" App for Android","id":"CVE-2024-23388","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"To maintain compliance with CNA rules, we have rejected this CVE record because it has not been used.","id":"CVE-2024-23389"},"packages":[],"prev":{"headline":"Cross-site scripting in FusionPBX","id":"CVE-2024-23387"},"products":["\"Mercari\" App for Android"],"published":"2024-01-26","related":[{"cvss_score":8.1,"headline":"Code injection in Android App 'Mercari' (Japan version)","id":"CVE-2020-5604","kev_date_added":null,"published":"2020-07-09"},{"cvss_score":7.5,"headline":"Missing authorization in Android App 'Mercari (Merpay) - Marketplace and Mobile Payments App' (Japan version)","id":"CVE-2021-20835","kev_date_added":null,"published":"2021-11-24"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-03","vendors":["Mercari, Inc."]},"summary":"A remote attacker can redirect users to arbitrary websites via a custom URL scheme, facilitating phishing attacks against Mercari Android app users.","url":"https://insights.sbomify.com/CVE-2024-23388/"}
