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-2021-28546 in the wild and no public exploit code.\n\nAffected product: Adobe Acrobat. 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-2021-28546/ (Markdown: https://insights.sbomify.com/CVE-2021-28546/index.md)","id":"CVE-2021-28546","markdown":"https://insights.sbomify.com/CVE-2021-28546/index.md","name":"CVE-2021-28546","record":{"aliases":["GHSA-v28v-fvcc-8q35"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PDF reader","requires_auth":"none","summary":"Attackers can modify certified PDF content without invalidating the certification, bypassing integrity checks in Adobe Acrobat Reader.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"acrobat","vendor":"adobe"},{"product":"acrobat_dc","vendor":"adobe"},{"product":"acrobat_reader","vendor":"adobe"},{"product":"acrobat_reader_dc","vendor":"adobe"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-353","name":"Missing Support for Integrity Check"}],"description":"Acrobat Reader DC versions versions 2020.013.20074 (and earlier), 2020.001.30018 (and earlier) and 2017.011.30188 (and earlier) are missing support for an integrity check.
