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-2025-5399 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-2025-5399/ (Markdown: https://insights.sbomify.com/CVE-2025-5399/index.md)","id":"CVE-2025-5399","markdown":"https://insights.sbomify.com/CVE-2025-5399/index.md","name":"CVE-2025-5399","record":{"aliases":["ALPINE-CVE-2025-5399","BELL-CVE-2025-5399","CLEANSTART-2026-YU63094","CURL-CVE-2025-5399","DEBIAN-CVE-2025-5399","ECHO-0bd5-994d-5bb9","GHSA-8h93-38hx-vv92","JLSEC-2026-434","MINI-ppm5-3j96-36r2","openSUSE-SU-2025:15213-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libcurl library","requires_auth":"none","summary":"A malicious server can trigger an endless busy-loop in libcurl's WebSocket code, causing a denial of service in applications using the library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"Due to a mistake in libcurl's WebSocket code, a malicious server can send a\nparticularly crafted packet which makes libcurl get trapped in an endless\nbusy-loop.\n\nThere is no other way for the application to escape or exit this loop other\nthan killing the thread/process.\n\nThis might be used to DoS libcurl-using application.","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"WebSocket endless loop","id":"CVE-2025-5399","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"haxx:curl","products":["haxx:curl"],"type":"denial_of_service","year":"2025"},"n_packages":1,"n_references":3,"next":{"headline":"chaitak-gorai Blogbook GET Parameter user.php sql injection","id":"CVE-2025-5400"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["8.14.1-4.1"],"introduced":["0"],"last_affected":[],"package":"curl","purl":"pkg:rpm/opensuse/curl\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2025:15213-1"}],"prev":{"headline":"Ninja Forms \u003c= 3.10.2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via CSTI","id":"CVE-2025-5398"},"products":["curl"],"published":"2025-06-07","related":[{"cvss_score":9.8,"headline":"Negotiate ambient user conn reuse","id":"CVE-2026-19931","kev_date_added":null,"published":"2026-09-06"},{"cvss_score":9.8,"headline":"HTTP/2 stream-dependency tree UAF","id":"CVE-2026-10536","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"cross-origin Digest auth state leak","id":"CVE-2026-11856","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"SASL double-free","id":"CVE-2026-8925","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"stale proxy password leak","id":"CVE-2026-9079","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":9.8,"headline":"Code injection in curl","id":"CVE-2016-4606","kev_date_added":null,"published":"2020-02-21"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2016-9953","kev_date_added":null,"published":"2018-03-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-09","vendors":["curl"]},"summary":"A malicious server can trigger an endless busy-loop in libcurl's WebSocket code, causing a denial of service in applications using the library.","url":"https://insights.sbomify.com/CVE-2025-5399/"}
