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-2016-8503 in the wild and no public exploit code.\n\nAffected product: Yandex Browser for desktop. 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-2016-8503/ (Markdown: https://insights.sbomify.com/CVE-2016-8503/index.md)","id":"CVE-2016-8503","markdown":"https://insights.sbomify.com/CVE-2016-8503/index.md","name":"CVE-2016-8503","record":{"aliases":["GHSA-mrv4-rm2c-4pcm"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Yandex Browser","requires_auth":"none","summary":"Remote attackers can bypass anti-phishing warnings in Yandex Browser to brute-force passwords for important web resources using special JavaScript.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"yandex","cpe":[{"product":"yandex_browser","vendor":"yandex"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-254","name":null}],"description":"Yandex Protect Anti-phishing warning in Yandex Browser for desktop from version 16.7 to 16.9 could be used by remote attacker for brute-forcing passwords from important web-resource with special JavaScript.","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":"Security feature bypass in Yandex Browser for desktop","id":"CVE-2016-8503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site request forgery in Yandex Browser for desktop","id":"CVE-2016-8504"},"packages":[],"prev":{"headline":"Security feature bypass in Yandex Browser for desktop","id":"CVE-2016-8502"},"products":["Yandex Browser for desktop"],"published":"2016-10-26","related":[{"cvss_score":8.4,"headline":"DLL Hijacking in Yandex Browser","id":"CVE-2024-6473","kev_date_added":null,"published":"2024-09-03"},{"cvss_score":8.3,"headline":"Yandex Browser Lite for Android prior to version 21.1.0 allows remote attackers to cause a denial of service.","id":"CVE-2021-25255","kev_date_added":null,"published":"2025-05-21"},{"cvss_score":8.2,"headline":"Yandex Browser Lite for Android before 21.1.0 allows remote attackers to spoof the address bar.","id":"CVE-2021-25254","kev_date_added":null,"published":"2025-05-21"},{"cvss_score":7.8,"headline":"Privilege escalation in Yandex Browser (Desktop)","id":"CVE-2021-25261","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.8,"headline":"Privilege escalation in Yandex Browser (Desktop)","id":"CVE-2022-28225","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.8,"headline":"Privilege escalation in Yandex Browser (Desktop)","id":"CVE-2022-28226","kev_date_added":null,"published":"2022-06-15"},{"cvss_score":7.8,"headline":"Privilege escalation in Yandex Browser (Desktop)","id":"CVE-2021-25263","kev_date_added":null,"published":"2021-08-17"}],"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":"2024-08-06","vendors":["Yandex N.V."]},"summary":"Remote attackers can bypass anti-phishing warnings in Yandex Browser to brute-force passwords for important web resources using special JavaScript.","url":"https://insights.sbomify.com/CVE-2016-8503/"}
