An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-76443 exists.\n\nAffected product: Cisco Secure Email. 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-2026-76443/ (Markdown: https://insights.sbomify.com/CVE-2026-76443/index.md)","id":"CVE-2026-76443","markdown":"https://insights.sbomify.com/CVE-2026-76443/index.md","name":"CVE-2026-76443","record":{"aliases":["GHSA-7r4m-5539-57x5"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Secure Email Gateway","requires_auth":"none","summary":"Cisco Secure Email Gateway received security hardening updates to address internally discovered vulnerabilities related to improper neutralization.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-707","name":"Improper Neutralization"}],"description":"As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Secure Email Gateway and Cisco Secure Email and Web Manager engineering team has conducted a comprehensive internal security review.
