It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-21036 in the wild and no public exploit code.\n\nAffected product: Google 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-2023-21036/ (Markdown: https://insights.sbomify.com/CVE-2023-21036/index.md)","id":"CVE-2023-21036","markdown":"https://insights.sbomify.com/CVE-2023-21036/index.md","name":"CVE-2023-21036","record":{"aliases":["A-264261868","GHSA-c4q4-j9gc-fpq4","PUB-A-264261868"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Android OS","requires_auth":"low_privilege","summary":"A logic error in Android's BitmapExport.java fails to truncate images, potentially allowing unauthorized data access.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"google_android","cpe":[{"product":"android","vendor":"google"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-703","name":"Improper Check or Handling of Exceptional Conditions"}],"description":"In BitmapExport.java, there is a possible failure to truncate images due to a logic error in the code.Product: AndroidVersions: Android kernelAndroid ID: A-264261868References: N/A","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-03-19","github_poc":6,"max_poc_stars":81,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-03-22T14:59:42Z","kind":"github_poc","ref":"https://github.com/infobyte/CVE-2023-21036","stars":81,"title":"Detection and sanitization for Acropalypse Now - CVE-2023-21036"},{"date":"2023-03-19T02:15:23Z","kind":"github_poc","ref":"https://github.com/qixils/AntiCropalypse","stars":22,"title":"Discord bot for mitigating the aCropalypse vulnerability (CVE-2023-21036, CVE-2023-28303) by retroactively deleting vulnerable images"},{"date":"2023-04-01T00:08:15Z","kind":"github_poc","ref":"https://github.com/lordofpipes/acropadetect","stars":3,"title":"Web tool for detecting Acropalypse (CVE-2023-21036) https://lordofpipes.github.io/acropadetect/"},{"date":"2023-03-25T21:30:57Z","kind":"github_poc","ref":"https://github.com/notaSWE/gocropalypse","stars":1,"title":"CVE-2023-21036 detection in Go"},{"date":"2026-06-15T07:29:41Z","kind":"github_poc","ref":"https://github.com/iqbaalilmii/acropalypse-reconstructor","stars":1,"title":"A lightweight CLI tool to detect and reconstruct cropped images vulnerable to Acropalypse (CVE-2023-21036 and CVE-2023-28303) written in Python."},{"date":"2026-04-17T01:46:46Z","kind":"github_poc","ref":"https://github.com/PolitoInc/XWFAcropalypse","stars":0,"title":"X-Ways Acropalypse extension detects CVE-2023-21036 in common images "}],"tier":"poc_unverified"},"has_fix":true,"headline":"Other in Android","id":"CVE-2023-21036","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"google:android","products":["google:android"],"type":"other","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Android","id":"CVE-2023-21038"},"packages":[],"prev":{"headline":"Privilege escalation in Android","id":"CVE-2023-21035"},"products":["Android"],"published":"2023-03-24","related":[{"cvss_score":8.8,"headline":"Google Pixel Improper Authorization","id":"CVE-2026-58704","kev_date_added":"2026-09-16","published":"2026-09-15"},{"cvss_score":8.8,"headline":"Android Runtime Use-After-Free","id":"CVE-2025-48543","kev_date_added":"2025-09-04","published":"2025-09-04"},{"cvss_score":8.8,"headline":"Android Framework Privilege Escalation","id":"CVE-2023-35674","kev_date_added":"2023-09-13","published":"2023-09-11"},{"cvss_score":8.4,"headline":"Android Framework Integer Overflow","id":"CVE-2025-48595","kev_date_added":"2026-06-02","published":"2026-06-01"},{"cvss_score":8.1,"headline":"Android Pixel Privilege Escalation","id":"CVE-2024-32896","kev_date_added":"2024-06-13","published":"2024-06-13"},{"cvss_score":7.8,"headline":"Android Framework Privilege Escalation","id":"CVE-2025-48572","kev_date_added":"2025-12-02","published":"2025-12-08"},{"cvss_score":7.8,"headline":"Android Pixel Privilege Escalation","id":"CVE-2024-29748","kev_date_added":"2024-04-04","published":"2024-04-05"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-25","vendors":["n/a"]},"summary":"A logic error in Android's BitmapExport.java fails to truncate images, potentially allowing unauthorized data access.","url":"https://insights.sbomify.com/CVE-2023-21036/"}
