Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-56771 in the wild and no public exploit code.\n\nAffected product: samuelclay NewsBlur. 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-2026-56771/ (Markdown: https://insights.sbomify.com/CVE-2026-56771/index.md)","id":"CVE-2026-56771","markdown":"https://insights.sbomify.com/CVE-2026-56771/index.md","name":"CVE-2026-56771","record":{"aliases":["GHSA-hggv-jxwf-w664"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"NewsBlur web application","requires_auth":"low_privilege","summary":"Authenticated users can exploit an SSRF flaw in NewsBlur to access internal networks and cloud metadata, leading to sensitive data exfiltration.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"NewsBlur before version 14.5.0 contains a server-side request forgery vulnerability in the add_url endpoint that allows authenticated users to make arbitrary server requests to internal networks by failing to filter private IP addresses.
