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-2013-6634 in the wild and no public exploit code.\n\nAffected product: Google Chrome. 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-2013-6634/ (Markdown: https://insights.sbomify.com/CVE-2013-6634/index.md)","id":"CVE-2013-6634","markdown":"https://insights.sbomify.com/CVE-2013-6634/index.md","name":"CVE-2013-6634","record":{"aliases":["GHSA-74gf-43jg-q6vr"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Chrome browser","requires_auth":"none","summary":"Remote attackers can hijack web sessions via session fixation in Chrome's one-click sign-in helper, requiring user interaction to trigger improper sync.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"chrome","vendor":"google"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The OneClickSigninHelper::ShowInfoBarIfPossible function in browser/ui/sync/one_click_signin_helper.cc in Google Chrome before 31.0.1650.63 uses an incorrect URL during realm validation, which allows remote attackers to conduct session fixation attacks and hijack web sessions by triggering improper sync after a 302 (aka Found) HTTP status code.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Auth bypass in n/a","id":"CVE-2013-6634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:chrome","products":["google:chrome"],"type":"auth_bypass","year":"2013"},"n_packages":0,"n_references":9,"next":{"headline":"Use after free in n/a","id":"CVE-2013-6635"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2013-6632"},"products":["n/a"],"published":"2013-12-07","related":[{"cvss_score":9.6,"headline":"Google Chromium GPU Heap Buffer Overflow","id":"CVE-2022-4135","kev_date_added":"2022-11-28","published":"2022-11-25"},{"cvss_score":9.6,"headline":"Google Chrome Use-After-Free","id":"CVE-2020-16017","kev_date_added":"2021-11-03","published":"2021-01-08"},{"cvss_score":9.6,"headline":"Google Chrome for Android UI Heap Buffer Overflow","id":"CVE-2020-16010","kev_date_added":"2021-11-03","published":"2020-11-03"},{"cvss_score":8.8,"headline":"Google Chromium V8 Out of Bounds Write","id":"CVE-2026-87491","kev_date_added":"2026-09-09","published":"2026-09-09"},{"cvss_score":8.8,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2026-85046","kev_date_added":"2026-09-04","published":"2026-09-03"},{"cvss_score":8.8,"headline":"Google Chromium V8 Out-of-Bounds Read and Write","id":"CVE-2026-11645","kev_date_added":"2026-06-09","published":"2026-06-08"},{"cvss_score":8.8,"headline":"Google Dawn Use-After-Free","id":"CVE-2026-5281","kev_date_added":"2026-04-01","published":"2026-04-01"}],"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":["n/a"]},"summary":"Remote attackers can hijack web sessions via session fixation in Chrome's one-click sign-in helper, requiring user interaction to trigger improper sync.","url":"https://insights.sbomify.com/CVE-2013-6634/"}
