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-2021-40721 in the wild and no public exploit code.\n\nAffected product: Adobe Connect. 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-2021-40721/ (Markdown: https://insights.sbomify.com/CVE-2021-40721/index.md)","id":"CVE-2021-40721","markdown":"https://insights.sbomify.com/CVE-2021-40721/index.md","name":"CVE-2021-40721","record":{"aliases":["GHSA-fwq9-fc5m-x5cc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Adobe Connect","requires_auth":"none","summary":"An attacker can execute malicious JavaScript in a victim's browser by tricking them into visiting a crafted URL in Adobe Connect.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"connect","vendor":"adobe"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Adobe Connect version 11.2.3 (and earlier) is affected by a reflected Cross-Site Scripting (XSS) vulnerability.
