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-2010-2766 in the wild and no public exploit code.\n\nAffected product: Mozilla Firefox. 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-2010-2766/ (Markdown: https://insights.sbomify.com/CVE-2010-2766/index.md)","id":"CVE-2010-2766","markdown":"https://insights.sbomify.com/CVE-2010-2766/index.md","name":"CVE-2010-2766","record":{"aliases":["GHSA-hhc2-ffw9-rjr6"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by exploiting a use-after-free vulnerability in the normalizeDocument function when visiting a malicious webpage.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"firefox","vendor":"mozilla"},{"product":"seamonkey","vendor":"mozilla"},{"product":"thunderbird","vendor":"mozilla"}],"cvss":{"score":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"The normalizeDocument function in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 does not properly handle the removal of DOM nodes during normalization, which might allow remote attackers to execute arbitrary code via vectors involving access to a deleted object.","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":"Use after free in n/a","id":"CVE-2010-2766","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mozilla:firefox","products":["mozilla:firefox","mozilla:seamonkey","mozilla:thunderbird"],"type":"use_after_free","year":"2010"},"n_packages":0,"n_references":14,"next":{"headline":"Use after free in n/a","id":"CVE-2010-2767"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2010-2765"},"products":["n/a"],"published":"2010-09-09","related":[{"cvss_score":10,"headline":"Mozilla Firefox and Thunderbird Sandbox Escape","id":"CVE-2019-11708","kev_date_added":"2022-05-23","published":"2019-07-23"},{"cvss_score":9.8,"headline":"Mozilla Multiple Products Remote Code Execution","id":"CVE-2010-3765","kev_date_added":"2025-10-06","published":"2010-10-27"},{"cvss_score":9.6,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2022-26486","kev_date_added":"2022-03-07","published":"2022-12-22"},{"cvss_score":8.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2022-26485","kev_date_added":"2022-03-07","published":"2022-12-22"},{"cvss_score":8.8,"headline":"Mozilla Firefox and Thunderbird Type Confusion","id":"CVE-2019-11707","kev_date_added":"2022-05-23","published":"2019-07-23"},{"cvss_score":8.1,"headline":"Mozilla Firefox And Thunderbird Use-After-Free","id":"CVE-2020-6819","kev_date_added":"2021-11-03","published":"2020-04-24"},{"cvss_score":8.1,"headline":"Mozilla Firefox And Thunderbird Use-After-Free","id":"CVE-2020-6820","kev_date_added":"2021-11-03","published":"2020-04-24"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by exploiting a use-after-free vulnerability in the normalizeDocument function when visiting a malicious webpage.","url":"https://insights.sbomify.com/CVE-2010-2766/"}
