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-2021-29448 in the wild and no public exploit code.\n\nAffected product: pi-hole AdminLTE. 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-2021-29448/ (Markdown: https://insights.sbomify.com/CVE-2021-29448/index.md)","id":"CVE-2021-29448","markdown":"https://insights.sbomify.com/CVE-2021-29448/index.md","name":"CVE-2021-29448","record":{"aliases":["GHSA-cwwf-93p7-73j9"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Pi-hole Admin Interface","requires_auth":"none","summary":"An attacker with network access to the DNS server can inject malicious scripts into the Pi-hole Admin portal, potentially compromising administrator sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ftldns","vendor":"pi-hole"},{"product":"pi-hole","vendor":"pi-hole"},{"product":"web_interface","vendor":"pi-hole"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Pi-hole is a Linux network-level advertisement and Internet tracker blocking application.
