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-2025-71375 exists.\n\nAffected packages and fixed versions:\n- picklescan (PyPI): affected all versions; fixed in 0.0.34\n- picklescan (PyPI): affected all versions; fixed in 0.0.34\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-2025-71375/ (Markdown: https://insights.sbomify.com/CVE-2025-71375/index.md)","id":"CVE-2025-71375","markdown":"https://insights.sbomify.com/CVE-2025-71375/index.md","name":"CVE-2025-71375","record":{"aliases":["GHSA-955r-x9j8-7rhh","GHSA-xgj3-g5r2-m8rf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python pickle scanner","requires_auth":"none","summary":"Attackers can bypass picklescan detection using _operator.methodcaller to execute arbitrary code via malicious pickle files.","user_interaction":"required","vuln_class":"deserialization"},"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:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"picklescan before 0.0.34 fails to detect the _operator.methodcaller built-in function when scanning pickle files for malicious code.
