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-2021-25254 in the wild and no public exploit code.\n\nAffected product: Yandex Browser Lite. 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-2021-25254/ (Markdown: https://insights.sbomify.com/CVE-2021-25254/index.md)","id":"CVE-2021-25254","markdown":"https://insights.sbomify.com/CVE-2021-25254/index.md","name":"CVE-2021-25254","record":{"aliases":["GHSA-mjcq-3whq-7xjh"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Android web browser","requires_auth":"none","summary":"Remote attackers can spoof the address bar in Yandex Browser Lite for Android, potentially misleading users about the current site.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"yandex","cpe":[{"product":"yandex_browser","vendor":"yandex"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"Yandex Browser Lite for Android before 21.1.0 allows remote attackers to spoof the address bar.","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":"Yandex Browser Lite for Android before 21.1.0 allows remote attackers to spoof the address bar.","id":"CVE-2021-25254","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":0,"n_references":1,"next":{"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"},"packages":[],"prev":{"headline":"Privilege escalation in Trend Micro Apex One","id":"CVE-2021-25253"},"products":["Browser Lite"],"published":"2025-05-21","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":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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-21","vendors":["Yandex"]},"summary":"Remote attackers can spoof the address bar in Yandex Browser Lite for Android, potentially misleading users about the current site.","url":"https://insights.sbomify.com/CVE-2021-25254/"}
