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-2021-24041 in the wild and no public exploit code.\n\nAffected product: Facebook WhatsApp Business for Android. 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-2021-24041/ (Markdown: https://insights.sbomify.com/CVE-2021-24041/index.md)","id":"CVE-2021-24041","markdown":"https://insights.sbomify.com/CVE-2021-24041/index.md","name":"CVE-2021-24041","record":{"aliases":["GHSA-rwm6-qx2j-8fmr"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WhatsApp Android","requires_auth":"none","summary":"A missing bounds check in WhatsApp for Android allowed attackers to execute arbitrary code via a malicious image sent to a user.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"facebook","cpe":[{"product":"whatsapp","vendor":"whatsapp"},{"product":"whatsapp_business","vendor":"whatsapp"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A missing bounds check in image blurring code prior to WhatsApp for Android v2.21.22.7 and WhatsApp Business for Android v2.21.22.7 could have allowed an out-of-bounds write if a user sent a malicious image.","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":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24041","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24042"},"packages":[],"prev":{"headline":"Deserialization in ParlAI","id":"CVE-2021-24040"},"products":["WhatsApp Business for Android","WhatsApp for Android"],"published":"2021-12-07","related":[{"cvss_score":9.8,"headline":"WhatsApp VOIP Stack Buffer Overflow","id":"CVE-2019-3568","kev_date_added":"2022-04-19","published":"2019-05-14"},{"cvss_score":8.2,"headline":"WhatsApp Cross-Site Scripting","id":"CVE-2019-18426","kev_date_added":"2022-05-23","published":"2020-01-21"},{"cvss_score":5.4,"headline":"Meta Platforms WhatsApp Incorrect Authorization","id":"CVE-2025-55177","kev_date_added":"2025-09-02","published":"2025-08-29"},{"cvss_score":9.8,"headline":"Integer overflow in WhatsApp Business for Android","id":"CVE-2022-36934","kev_date_added":null,"published":"2022-09-22"},{"cvss_score":9.8,"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24042","kev_date_added":null,"published":"2022-01-04"},{"cvss_score":9.8,"headline":"Memory corruption in WhatsApp Business for Android","id":"CVE-2021-24026","kev_date_added":null,"published":"2021-04-06"}],"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":"2024-08-03","vendors":["Facebook"]},"summary":"A missing bounds check in WhatsApp for Android allowed attackers to execute arbitrary code via a malicious image sent to a user.","url":"https://insights.sbomify.com/CVE-2021-24041/"}
