Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-27534 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-2023-27534/ (Markdown: https://insights.sbomify.com/CVE-2023-27534/index.md)","id":"CVE-2023-27534","markdown":"https://insights.sbomify.com/CVE-2023-27534/index.md","name":"CVE-2023-27534","record":{"aliases":["ALPINE-CVE-2023-27534","AZL-25784","AZL-25806","AZL-25810","AZL-25847","AZL-34607","AZL-38611","CLEANSTART-2026-OG84654","CLSA-2023-1682347721","CLSA-2023-1682348435","CLSA-2023-1682348615","CLSA-2023-1682348848","CURL-CVE-2023-27534","DEBIAN-CVE-2023-27534","DLA-3763-1","ECHO-1eee-ac31-e743","GHSA-4j25-c9rf-fp5f","JLSEC-2026-406","SUSE-SU-2024:2009-1","SUSE-SU-2026:0494-1","UBUNTU-CVE-2023-27534"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"curl library","requires_auth":"low_privilege","summary":"Attackers can exploit a path traversal flaw in curl's SFTP implementation to bypass filters or execute arbitrary code via crafted paths.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"brocade_fabric_operating_system_firmware","vendor":"broadcom"},{"product":"fedora","vendor":"fedoraproject"},{"product":"curl","vendor":"haxx"},{"product":"active_iq_unified_manager","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":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A path traversal vulnerability exists in curl \u003c8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory.
