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-2025-54140 exists.\n\nAffected packages and fixed versions:\n- pyload-ng (PyPI): affected from 0.5.0b3.dev89; fixed in 0.5.0b3.dev90\n- pyload-ng (PyPI): affected from 0.5.0b3.dev89; fixed in 0.5.0b3.dev90\n- pyload-ng (PyPI): affected from 0.5.0b3.dev89; fixed in 0.5.0b3.dev90\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-2025-54140/ (Markdown: https://insights.sbomify.com/CVE-2025-54140/index.md)","id":"CVE-2025-54140","markdown":"https://insights.sbomify.com/CVE-2025-54140/index.md","name":"CVE-2025-54140","record":{"aliases":["GHSA-xqpg-92fq-grfg","PYSEC-2026-1823"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"pyLoad download manager","requires_auth":"none","summary":"Authenticated attackers can write arbitrary files via path traversal in pyLoad, potentially leading to remote code execution and privilege escalation.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"pyLoad is a free and open-source Download Manager written in pure Python. In version 0.5.0b3.dev89, an authenticated path traversal vulnerability exists in the /json/upload endpoint of pyLoad.
