An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-22523 and fix it if it is affected.\n\nWhat it is: CVE-2021-22523 is a high-severity vulnerability in Verastream Host Integrator., published on 22 Jul 2021. 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-2021-22523 in the wild and no public exploit code.\n\nAffected product: Verastream Host Integrator.. 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-2021-22523/ (Markdown: https://insights.sbomify.com/CVE-2021-22523/index.md)","id":"CVE-2021-22523","markdown":"https://insights.sbomify.com/CVE-2021-22523/index.md","name":"CVE-2021-22523","record":{"aliases":["GHSA-74g4-5hch-j7rm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Host Integration Server","requires_auth":"none","summary":"An XML External Entity vulnerability in Micro Focus Verastream Host Integrator allows attackers to hijack user sessions and control web browsers.","user_interaction":"required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microfocus","cpe":[{"product":"verastream_host_integrator","vendor":"microfocus"}],"cvss":{"score":7.6,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"XML External Entity vulnerability in Micro Focus Verastream Host Integrator, affecting version 7.8 Update 1 and earlier versions.
