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-2026-8661 in the wild and no public exploit code.\n\nAffected product: Rapid7 InsightConnect Markdown Plugin. 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-2026-8661/ (Markdown: https://insights.sbomify.com/CVE-2026-8661/index.md)","id":"CVE-2026-8661","markdown":"https://insights.sbomify.com/CVE-2026-8661/index.md","name":"CVE-2026-8661","record":{"aliases":["GHSA-6r62-qf74-xpgg"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Rapid7 InsightConnect plugin","requires_auth":"none","summary":"Remote attackers can trigger Server-Side Request Forgery and XSS via unsanitized Markdown input in the Rapid7 InsightConnect Markdown to PDF plugin.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"rapid7","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Server-Side Request Forgery in the markdown_to_pdf action of Rapid7 InsightConnect Markdown Plugin on Linux in versions prior to 4.0.2 allows remote attackers to make arbitrary outbound HTTP requests via unsanitized resource-loading HTML elements (img/src, CSS url(), @import) embedded in Markdown input.
