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-2021-22958 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- concrete5/concrete5 (Packagist): affected all versions; fixed in 8.5.5\n- concrete5/concrete5 (Packagist): affected all versions; fixed in 8.5.5\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-2021-22958/ (Markdown: https://insights.sbomify.com/CVE-2021-22958/index.md)","id":"CVE-2021-22958","markdown":"https://insights.sbomify.com/CVE-2021-22958/index.md","name":"CVE-2021-22958","record":{"aliases":["GHSA-284f-f2hw-j2gx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"concrete5 CMS","requires_auth":"none","summary":"Attackers can bypass localhost restrictions using decimal IP encoding to access internal services in concrete5.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"concrete_cms","vendor":"concretecms"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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-918","name":"Server-Side Request Forgery"}],"description":"A Server-Side Request Forgery vulnerability was found in concrete5 \u003c 8.5.5 that allowed a decimal notation encoded IP address to bypass the limitations in place for localhost allowing interaction with local services.
