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-2026-25722 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @anthropic-ai/claude-code (npm): affected all versions; fixed in 2.0.57\n- @anthropic-ai/claude-code (npm): affected all versions; fixed in 2.0.57\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-2026-25722/ (Markdown: https://insights.sbomify.com/CVE-2026-25722/index.md)","id":"CVE-2026-25722","markdown":"https://insights.sbomify.com/CVE-2026-25722/index.md","name":"CVE-2026-25722","record":{"aliases":["GHSA-66q4-vfjg-2qhh"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Claude Code CLI","requires_auth":"none","summary":"Attackers can bypass write protections in Claude Code to modify sensitive files or execute commands by manipulating directory changes within the context window.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"claude_code","vendor":"anthropic"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Claude Code is an agentic coding tool. Prior to version 2.0.57, Claude Code failed to properly validate directory changes when combined with write operations to protected folders. By using the cd command to navigate into sensitive directories like .claude, it was possible to bypass write protection and create or modify files without user confirmation. Reliably exploiting this required the ability to add untrusted content into a Claude Code context window.
