An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-27533 exists.\n\nAffected product: Fedoraproject Fedora. 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-2023-27533/ (Markdown: https://insights.sbomify.com/CVE-2023-27533/index.md)","id":"CVE-2023-27533","markdown":"https://insights.sbomify.com/CVE-2023-27533/index.md","name":"CVE-2023-27533","record":{"aliases":["ALPINE-CVE-2023-27533","AZL-25783","AZL-25804","AZL-25812","AZL-25894","AZL-34608","AZL-37878","CLEANSTART-2026-RI66182","CLSA-2026-1777463367","CLSA-2026-1777463593","CURL-CVE-2023-27533","DEBIAN-CVE-2023-27533","ECHO-2cba-07b8-6862","GHSA-xvw3-6q4f-2gcv","JLSEC-2026-405","UBUNTU-CVE-2023-27533"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"curl library","requires_auth":"none","summary":"Attackers can execute arbitrary code via malicious TELNET input in curl due to insufficient input validation during server negotiation.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"curl","vendor":"haxx"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"clustered_data_ontap","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"},{"product":"universal_forwarder","vendor":"splunk"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-75","name":"Failure to Sanitize Special Elements into a Different Plane"}],"description":"A vulnerability in input validation exists in curl \u003c8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and \"telnet options\" during server negotiation.
