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-2023-26104 exists.\n\nAffected packages and fixed versions:\n- lite-web-server (npm): affected all versions up to 1.2.2; no fix listed\n- lite-web-server (npm): affected all versions up to 1.2.2; no fix listed\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-2023-26104/ (Markdown: https://insights.sbomify.com/CVE-2023-26104/index.md)","id":"CVE-2023-26104","markdown":"https://insights.sbomify.com/CVE-2023-26104/index.md","name":"CVE-2023-26104","record":{"aliases":["GHSA-8237-3q5g-99fv"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js web server library","requires_auth":"none","summary":"Attackers can cause a denial of service in lite-web-server by sending HTTP requests with unparseable control characters.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"lite-web-server","vendor":"lite-web-server_project"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"All versions of the package lite-web-server are vulnerable to Denial of Service (DoS) when an attacker sends an HTTP request and includes control characters that the decodeURI() function is unable to parse.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Denial of Service vulnerability in lite-web-server","id":"CVE-2023-26104","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":2,"n_references":3,"next":{"headline":"mde utilities contains Prototype Pollution","id":"CVE-2023-26105"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.2"],"package":"lite-web-server","purl":null,"source":"GHSA-8237-3q5g-99fv"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["1.2.2"],"package":"lite-web-server","purl":"pkg:npm/lite-web-server","source":"GHSA-8237-3q5g-99fv"}],"prev":{"headline":"Regular Expression Denial of Service in Deno.upgradeWebSocket API","id":"CVE-2023-26103"},"products":["lite-web-server"],"published":"2023-02-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2025-03-11","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in lite-web-server by sending HTTP requests with unparseable control characters.","url":"https://insights.sbomify.com/CVE-2023-26104/"}
