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-2026-79660 exists.\n\nAffected packages and fixed versions:\n- github.com/lin-snow/Ech0 (Go): affected all versions; fixed in 1.4.8-0.20260503034700-cb8d7a997dd8\n- github.com/lin-snow/Ech0 (Go): affected all versions; fixed in 1.4.8-0.20260503034700-cb8d7a997dd8\n- github.com/lin-snow/ech0 (Go): affected all versions; fixed in 1.4.8-0.20260503034700-cb8d7a997dd8\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-2026-79660/ (Markdown: https://insights.sbomify.com/CVE-2026-79660/index.md)","id":"CVE-2026-79660","markdown":"https://insights.sbomify.com/CVE-2026-79660/index.md","name":"CVE-2026-79660","record":{"aliases":["GHSA-845p-52xj-2432","GHSA-rj4g-rqgh-rx9h","GO-2026-5626"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ech0 comment system","requires_auth":"none","summary":"Unauthenticated attackers can harvest guest commenter email addresses via public API endpoints in Ech0 due to improper JSON serialization.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Ech0 versions before 4.7.3 expose guest commenter email addresses through public API endpoints due to improper JSON serialization tags on the Comment model.
