An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-9621 and fix it if it is affected.\n\nWhat it is: CVE-2019-9621 is a high-severity server-side request forgery vulnerability in Synacor Zimbra Collaboration Suite, published on 30 Apr 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-9621 in the wild since at least 7 Jul 2025.\n\nAffected product: Synacor Zimbra Collaboration Suite. 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-2019-9621/ (Markdown: https://insights.sbomify.com/CVE-2019-9621/index.md)","id":"CVE-2019-9621","markdown":"https://insights.sbomify.com/CVE-2019-9621/index.md","name":"CVE-2019-9621","record":{"aliases":["GHSA-gf2h-5qx6-v9fr"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Zimbra Collaboration Suite","requires_auth":"none","summary":"Attackers can exploit a Server-Side Request Forgery vulnerability in the ProxyServlet component to access internal resources or bypass security controls.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zimbra_collaboration_suite","vendor":"synacor"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Zimbra Collaboration Suite before 8.6 patch 13, 8.7.x before 8.7.11 patch 10, and 8.8.x before 8.8.10 patch 7 or 8.8.x before 8.8.11 patch 3 allows SSRF via the ProxyServlet component.","ecosystems":[],"exploits":{"exploitdb":6,"first_seen":"2019-03-13","github_poc":1,"max_poc_stars":78,"metasploit":1,"nuclei":1,"refs":[{"date":"2019-05-06T15:47:20Z","kind":"github_poc","ref":"https://github.com/k8gege/ZimbraExploit","stars":78,"title":"Zimbra邮件系统漏洞 XXE/RCE/SSRF/Upload GetShell Exploit  1.
