An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-45559 exists.\n\nAffected product: Linecorp Line. 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-2023-45559/ (Markdown: https://insights.sbomify.com/CVE-2023-45559/index.md)","id":"CVE-2023-45559","markdown":"https://insights.sbomify.com/CVE-2023-45559/index.md","name":"CVE-2023-45559","record":{"aliases":["GHSA-wpvc-f948-8425"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Line messaging app","requires_auth":"none","summary":"Attackers can leak channel access tokens to send crafted notifications, potentially compromising user accounts in the Line messaging application.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"line","vendor":"linecorp"}],"cvss":{"score":8.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[],"description":"An issue in Tamaki_hamanoki Line v.13.6.1 allows attackers to send crafted notifications via leakage of the channel access token.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Information disclosure in n/a","id":"CVE-2023-45559","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linecorp:line","products":["linecorp:line"],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in n/a","id":"CVE-2023-45560"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2023-45558"},"products":["n/a"],"published":"2024-01-03","related":[{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43305","kev_date_added":null,"published":"2023-12-08"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43300","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Code injection in n/a","id":"CVE-2023-43301","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43302","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43303","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.2,"headline":"Information disclosure in n/a","id":"CVE-2023-43304","kev_date_added":null,"published":"2023-12-07"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Attackers can leak channel access tokens to send crafted notifications, potentially compromising user accounts in the Line messaging application.","url":"https://insights.sbomify.com/CVE-2023-45559/"}
