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-2026-40157 exists.\n\nAffected packages and fixed versions:\n- praisonai (PyPI): affected from 2.7.2; fixed in 4.5.128\n- praisonai (PyPI): affected from 2.7.2; fixed in 4.5.128\n- PraisonAI (PyPI): affected from 2.7.2; fixed in 4.5.128\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-2026-40157/ (Markdown: https://insights.sbomify.com/CVE-2026-40157/index.md)","id":"CVE-2026-40157","markdown":"https://insights.sbomify.com/CVE-2026-40157/index.md","name":"CVE-2026-40157","record":{"aliases":["GHSA-99g3-w8gr-x37c","PYSEC-2026-469"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python AI library","requires_auth":"none","summary":"Attackers can overwrite arbitrary files via path traversal in PraisonAI recipe unpack, potentially leading to code execution.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"praisonai","vendor":"praison"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"PraisonAI is a multi-agent teams system.
