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 HSEC-2024-0001 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- keter (Hackage): affected from 0.3.4; fixed in 1.8.4\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/HSEC-2024-0001/ (Markdown: https://insights.sbomify.com/HSEC-2024-0001/index.md)","id":"HSEC-2024-0001","markdown":"https://insights.sbomify.com/HSEC-2024-0001/index.md","name":"HSEC-2024-0001","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Yesod app server","requires_auth":"none","summary":"Reflected XSS in Keter allows attackers to inject scripts via Host header, potentially leading to session hijacking or data theft.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"# Reflected XSS vulnerability in keter\n\nKeter is an app-server/reverse-proxy often used with webapps build on Yesod web-framework.\n\nIn the logic handling VHost dispatch, Keter was echoing back `Host` header value, unescaped,\nas part of an HTML error page.
