An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-47712 in the wild and no public exploit code.\n\nAffected product: Kentico Xperience. 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-2021-47712/ (Markdown: https://insights.sbomify.com/CVE-2021-47712/index.md)","id":"CVE-2021-47712","markdown":"https://insights.sbomify.com/CVE-2021-47712/index.md","name":"CVE-2021-47712","record":{"aliases":["GHSA-9jrm-mcr7-5p6m"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kentico Xperience CMS","requires_auth":"none","summary":"Attackers can manipulate URL hash values due to weak cryptography, potentially bypassing security controls in Kentico Xperience.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"xperience","vendor":"kentico"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"A cryptography vulnerability in Kentico Xperience allows attackers to potentially manipulate URL hash values through existing hashing mechanisms.
