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-2026-5773 exists.\n\nAffected product: Haxx Curl. 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-2026-5773/ (Markdown: https://insights.sbomify.com/CVE-2026-5773/index.md)","id":"CVE-2026-5773","markdown":"https://insights.sbomify.com/CVE-2026-5773/index.md","name":"CVE-2026-5773","record":{"aliases":["ALPINE-CVE-2026-5773","BELL-CVE-2026-5773","CLSA-2026-1779098432","CLSA-2026-1779357116","CLSA-2026-1779357393","CLSA-2026-1779357606","CLSA-2026-1779357791","CLSA-2026-1779358008","CLSA-2026-1779358120","CURL-CVE-2026-5773","DEBIAN-CVE-2026-5773","ECHO-73da-59b1-befa","GHSA-rp9q-8q5w-ch44","JLSEC-2026-1205","MINI-h4jq-xcr6-grr6","MINI-rpcf-hgm3-fwch","ROOT-OS-ALPINE-315-CVE-2026-5773","ROOT-OS-ALPINE-320-CVE-2026-5773","ROOT-OS-ALPINE-321-CVE-2026-5773","ROOT-OS-ALPINE-322-CVE-2026-5773","ROOT-OS-DEBIAN-11-CVE-2026-5773","ROOT-OS-DEBIAN-12-CVE-2026-5773","UBUNTU-CVE-2026-5773"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"libcurl SMB library","requires_auth":"none","summary":"libcurl may reuse incorrect SMB connections, causing downloads of wrong files or uploads to wrong locations due to logical errors in connection pooling.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"curl","cpe":[{"product":"curl","vendor":"haxx"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-488","name":"Exposure of Data Element to Wrong Session"}],"description":"libcurl might in some circumstances reuse the wrong connection for SMB(S)\ntransfers.\n\nlibcurl features a pool of recent connections so that subsequent requests can\nreuse an existing connection to avoid overhead.\n\nWhen reusing a connection a range of criteria must be met.
