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-2026-50134 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/gohugoio/hugo (Go): affected from 0.91.0; fixed in 0.162.0\n- github.com/gohugoio/hugo (Go): affected from 0.91.0; fixed in 0.162.0\n- github.com/gohugoio/hugo (Go): affected from 0.91.0; fixed in 0.162.0\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-2026-50134/ (Markdown: https://insights.sbomify.com/CVE-2026-50134/index.md)","id":"CVE-2026-50134","markdown":"https://insights.sbomify.com/CVE-2026-50134/index.md","name":"CVE-2026-50134","record":{"aliases":["DEBIAN-CVE-2026-50134","GHSA-vxgm-5rmg-5w8g","GO-2026-5681","JLSEC-2026-795","UBUNTU-CVE-2026-50134"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Hugo static site generator","requires_auth":"none","summary":"Attackers can bypass URL allow-lists in Hugo's remote resource fetching via HTTP redirects, accessing forbidden hosts and reading sensitive data.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"hugo","vendor":"gohugo"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Hugo is a static site generator. From 0.91.0 until 0.162.0, resources.GetRemote enforces security.http.urls on the URL it is called with, but it did not re-validate intermediate URLs on HTTP 3xx redirects. An allowed server (or an attacker controlling its DNS or response) could therefore redirect the request to a host that the policy was meant to forbid and Hugo would fetch from the redirected target.
