An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-82020 in the wild and no public exploit code.\n\nAffected product: NousResearch hermes-agent. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-82020/ (Markdown: https://insights.sbomify.com/CVE-2026-82020/index.md)","id":"CVE-2026-82020","markdown":"https://insights.sbomify.com/CVE-2026-82020/index.md","name":"CVE-2026-82020","record":{"aliases":["GHSA-rrm3-x23q-98qc"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"AI agent library","requires_auth":"none","summary":"Attackers can overwrite credential stores via file-write tools by bypassing path restrictions, leading to credential tampering or unauthorized access.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-552","name":"Files or Directories Accessible to External Parties"}],"description":"Hermes Agent 0.16.0 prior to 0.17.0 contains an improper path restriction vulnerability that allows attackers who can influence ingested message content to overwrite the credential store by bypassing sensitive-path guards that excluded the auth.json file.
