An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45727 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- cloakbrowser (PyPI): affected all versions; fixed in 0.3.28\n- cloakbrowser (PyPI): affected all versions; fixed in 0.3.28\n- cloakbrowser (PyPI): affected all versions; fixed in 0.3.28\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-2026-45727/ (Markdown: https://insights.sbomify.com/CVE-2026-45727/index.md)","id":"CVE-2026-45727","markdown":"https://insights.sbomify.com/CVE-2026-45727/index.md","name":"CVE-2026-45727","record":{"aliases":["GHSA-mf33-gv72-w2h5","PYSEC-2026-2420"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"CloakBrowser CDP multiplexer","requires_auth":"none","summary":"Unauthenticated attackers can delete arbitrary directories via path traversal in the fingerprint parameter of CloakBrowser's cloakserve component.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"CloakBrowser is a tool to bypass bot detection tests. Prior to version 0.3.28, the cloakserve CDP multiplexer uses the user-supplied fingerprint query parameter directly as a filesystem path component when creating Chrome profile directories. An unauthenticated attacker who can reach the cloakserve port can supply a crafted fingerprint value containing path traversal sequences to resolve user_data_dir outside the configured data_dir. When Chrome fails to start or the process is cleaned up, shutil.rmtree() deletes the traversed path, resulting in arbitrary directory deletion. Additionally, cloakserve bound to 0.0.0.0 by default, making it network-exposed.
