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-2026-34581 exists.\n\nAffected packages and fixed versions:\n- github.com/patrickhener/goshs (Go): affected from 1.1.0; no fix listed\n- github.com/patrickhener/goshs (Go): affected from 1.1.0; no fix listed\n- github.com/patrickhener/goshs (Go): affected from 1.1.0; no fix listed\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-2026-34581/ (Markdown: https://insights.sbomify.com/CVE-2026-34581/index.md)","id":"CVE-2026-34581","markdown":"https://insights.sbomify.com/CVE-2026-34581/index.md","name":"CVE-2026-34581","record":{"aliases":["GHSA-jgfx-74g2-9r6g","GO-2026-5469"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Go HTTP server","requires_auth":"none","summary":"Attackers can bypass share token authentication in goshs to access restricted files and execute arbitrary code.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"goshs","vendor":"goshs"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"goshs is a SimpleHTTPServer written in Go.
