An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-50180 exists.\n\nAffected packages and fixed versions:\n- github.com/esm-dev/esm.sh (Go): affected all versions; fixed in 0.0.0-20250616164159-0593516c4cfa\n- github.com/esm-dev/esm.sh (Go): affected all versions; fixed in 0.0.0-20250616164159-0593516c4cfa\n- github.com/esm-dev/esm.sh (Go): affected all versions; fixed in 0.0.0-20250616164159-0593516c4cfa\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-2025-50180/ (Markdown: https://insights.sbomify.com/CVE-2025-50180/index.md)","id":"CVE-2025-50180","markdown":"https://insights.sbomify.com/CVE-2025-50180/index.md","name":"CVE-2025-50180","record":{"aliases":["GHSA-3c9r-837r-qqm4","GO-2026-4545"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"esm.sh CDN","requires_auth":"none","summary":"Attackers can exploit a full-response SSRF in esm.sh to retrieve sensitive information from internal websites.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"esm.sh","vendor":"esm"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"esm.sh is a no-build content delivery network (CDN) for web development.
