An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-70559 exists.\n\nAffected packages and fixed versions:\n- pdfminer-six (PyPI): affected all versions; fixed in 20251230\n- pdfminer-six (PyPI): affected all versions; fixed in 20251230\n- pdfminer.six (PyPI): affected all versions; fixed in 20251230\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-2025-70559/ (Markdown: https://insights.sbomify.com/CVE-2025-70559/index.md)","id":"CVE-2025-70559","markdown":"https://insights.sbomify.com/CVE-2025-70559/index.md","name":"CVE-2025-70559","record":{"aliases":["DEBIAN-CVE-2025-70559","DLA-4374-2","GHSA-f83h-ghpp-7wcc","OESA-2026-4210","OESA-2026-4211","PYSEC-2026-1761","UBUNTU-CVE-2025-70559"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Python PDF library","requires_auth":"none","summary":"An attacker can achieve arbitrary code execution or privilege escalation by placing a malicious pickle file in a location accessible to the pdfminer.six library.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"pdfminer.six before 20251230 contains an insecure deserialization vulnerability in the CMap loading mechanism.
