An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-49396 exists.\n\nAffected packages and fixed versions:\n- github.com/nezhahq/nezha (Go): affected from 1.0.0; no fix listed\n- github.com/nezhahq/nezha (Go): affected from 1.0.0; fixed in 2.0.14\n- github.com/nezhahq/nezha (Go): affected from 1.0.0; fixed in 2.0.14\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-2026-49396/ (Markdown: https://insights.sbomify.com/CVE-2026-49396/index.md)","id":"CVE-2026-49396","markdown":"https://insights.sbomify.com/CVE-2026-49396/index.md","name":"CVE-2026-49396","record":{"aliases":["GHSA-8qhj-4f8c-j8qg","GO-2026-5261"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nezha Monitoring","requires_auth":"none","summary":"Cross-site request forgery allows attackers to trigger stored cron commands on victim agents, leading to potential code execution.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O\u0026M tool.
