An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-61704 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- link-preview-js (npm): affected all versions; fixed in 4.0.4\n- link-preview-js (npm): affected all versions; fixed in 4.0.4\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-2026-61704/ (Markdown: https://insights.sbomify.com/CVE-2026-61704/index.md)","id":"CVE-2026-61704","markdown":"https://insights.sbomify.com/CVE-2026-61704/index.md","name":"CVE-2026-61704","record":{"aliases":["GHSA-cpjf-6666-r8fx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript link preview library","requires_auth":"none","summary":"An attacker can bypass SSRF protections via DNS rebinding to access internal network resources using the link-preview-js library.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","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"}],"description":"Link Preview JS extracts web links information. Prior to 4.0.4, the resolveDNSHost mitigation in index.ts validates one resolved IP address but fetches the original hostname, allowing an attacker-controlled DNS server to return a public address during validation and a loopback or internal address during the final connection. This DNS rebinding condition bypasses the SSRF protection and can cause the server-side preview fetch to reach internal HTTP resources. Redirect handling is affected by the same validation-to-fetch mismatch. This issue is fixed in version 4.0.4.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"link-preview-js DNS Rebinding SSRF Bypass / Incomplete Fix for CVE-2026-43897","id":"CVE-2026-61704","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":2,"n_references":5,"next":{"headline":"SOCFortress CoPilot: Stored case-report template injection permits backend code execution","id":"CVE-2026-61707"},"packages":[{"ecosystem":"npm","fixed":["4.0.4"],"introduced":["0"],"last_affected":[],"package":"link-preview-js","purl":null,"source":"GHSA-cpjf-6666-r8fx"},{"ecosystem":"npm","fixed":["4.0.4"],"introduced":["0"],"last_affected":[],"package":"link-preview-js","purl":"pkg:npm/link-preview-js","source":"GHSA-cpjf-6666-r8fx"}],"prev":{"headline":"OpenPrinting CUPS: root-side banner file disclosure","id":"CVE-2026-61702"},"products":["link-preview-js"],"published":"2026-08-20","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-25","vendors":["OP-Engineering"]},"summary":"An attacker can bypass SSRF protections via DNS rebinding to access internal network resources using the link-preview-js library.","url":"https://insights.sbomify.com/CVE-2026-61704/"}
