An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86419 in the wild and no public exploit code.\n\nAffected product: Misp-Project Misp. 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-2026-86419/ (Markdown: https://insights.sbomify.com/CVE-2026-86419/index.md)","id":"CVE-2026-86419","markdown":"https://insights.sbomify.com/CVE-2026-86419/index.md","name":"CVE-2026-86419","record":{"aliases":["GHSA-qp9m-r348-236g"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing platform","requires_auth":"high_privilege","summary":"Attackers can exploit insufficient URL validation in MISP feeds and TAXII discovery to perform SSRF and leak credentials via redirects.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[{"product":"misp","vendor":"misp-project"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:L/VA:H/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Affected versions of MISP contain insufficient validation of server-side outbound HTTP destinations in feed retrieval and TAXII discovery functionality.\n\nIn feed processing, redirects were followed without validating the redirect scheme or destination. The original request headers were reused across redirect hops, meaning authentication headers or API credentials configured for a feed could be forwarded to a different host. Redirects could also target internal network resources, resulting in SSRF. The fix adds redirect validation, blocks internal destinations for cross-host redirects, strips configured feed credentials before following redirects to another host, and pins validated DNS results to prevent re-resolution after validation.\n\nThe TAXII discovery endpoint had a related incomplete SSRF defense. It used gethostbyname() and compared the result against only a few literal addresses. This missed cases including IPv6 loopback (::1), numeric host encodings such as 0x7f000001, and potentially multiple DNS records. The fix moves TAXII discovery to the shared URL egress validator.\n\nTogether, these commits harden MISP's outbound URL handling against alternate-address representations, DNS-related bypasses, unsafe redirects, internal-host access, and cross-host credential forwarding.\n\nVersion affected: ≤2.5.45","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"MISP Insufficient Outbound URL Validation Allows SSRF and Credential Disclosure via Feed Redirects and TAXII Discovery","id":"CVE-2026-86419","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"misp-project:misp","products":["misp-project:misp"],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"ImageMagick before 7.1.2-30 Denial of Service Memory Budget","id":"CVE-2026-86420"},"packages":[],"prev":{"headline":"MISP Dashboard Organisation Picker Exposes Hidden Organisation Metadata to Unauthorized Users","id":"CVE-2026-86418"},"products":["MISP"],"published":"2026-09-07","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-46918","kev_date_added":null,"published":"2024-09-15"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-45509","kev_date_added":null,"published":"2024-09-01"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29858","kev_date_added":null,"published":"2024-03-21"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29859","kev_date_added":null,"published":"2024-03-21"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-25674","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-25675","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2023-50918","kev_date_added":null,"published":"2023-12-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-08","vendors":["MISP"]},"summary":"Attackers can exploit insufficient URL validation in MISP feeds and TAXII discovery to perform SSRF and leak credentials via redirects.","url":"https://insights.sbomify.com/CVE-2026-86419/"}
