It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-40111 exists.\n\nAffected packages and fixed versions:\n- praisonaiagents (PyPI): affected all versions; fixed in 1.5.128\n- praisonaiagents (PyPI): affected all versions; fixed in 1.5.128\n- praisonaiagents (PyPI): affected all versions; fixed in 1.5.128\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-2026-40111/ (Markdown: https://insights.sbomify.com/CVE-2026-40111/index.md)","id":"CVE-2026-40111","markdown":"https://insights.sbomify.com/CVE-2026-40111/index.md","name":"CVE-2026-40111","record":{"aliases":["GHSA-v7px-3835-7gjx","PYSEC-2026-487"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Python AI agent library","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands via unsanitized input in memory hooks, potentially gaining full control of the host system.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"praisonaiagents","vendor":"praison"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, he memory hooks executor in praisonaiagents passes a user-controlled command string directly to subprocess.run() with shell=True at src/praisonai-agents/praisonaiagents/memory/hooks.py. No sanitization is performed and shell metacharacters are interpreted by /bin/sh before the intended command executes. Two independent attack surfaces exist. The first is via pre_run_command and post_run_command hook event types registered through the hooks configuration. The second and more severe surface is the .praisonai/hooks.json lifecycle configuration, where hooks registered for events such as BEFORE_TOOL and AFTER_TOOL fire automatically during agent operation. An agent that gains file-write access through prompt injection can overwrite .praisonai/hooks.json and have its payload execute silently at every subsequent lifecycle event without further user interaction. This vulnerability is fixed in 1.5.128.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"PraisonAIAgents has an OS Command Injection via shell=True in Memory Hooks Executor (memory/hooks.py)","id":"CVE-2026-40111","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"PraisonAI has Stored XSS via Unsanitized Agent Output in HTML Rendering (nh3 Not a Required Dependency)","id":"CVE-2026-40112"},"packages":[{"ecosystem":"PyPI","fixed":["1.5.128"],"introduced":["0"],"last_affected":[],"package":"praisonaiagents","purl":null,"source":"GHSA-v7px-3835-7gjx"},{"ecosystem":"PyPI","fixed":["1.5.128"],"introduced":["0"],"last_affected":[],"package":"praisonaiagents","purl":"pkg:pypi/praisonaiagents","source":"GHSA-v7px-3835-7gjx"},{"ecosystem":"PyPI","fixed":["1.5.128"],"introduced":["0"],"last_affected":[],"package":"praisonaiagents","purl":"pkg:pypi/praisonaiagents","source":"PYSEC-2026-487"}],"prev":{"headline":"jupyter-server CORS origin validation bypass via unanchored regex in allow_origin_pat","id":"CVE-2026-40110"},"products":["PraisonAIAgents"],"published":"2026-04-09","related":[{"cvss_score":10,"headline":"PraisonAI: Python Sandbox Escape via str Subclass startswith() Override in execute_code","id":"CVE-2026-34938","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":8.6,"headline":"PraisonAI: SSRF in FileTools.download_file() via Unvalidated URL","id":"CVE-2026-34954","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":7.8,"headline":"PraisonAI: Shell Injection in run_python() via Unescaped $() Substitution","id":"CVE-2026-34937","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":7.7,"headline":"SSRF bypass in PraisonAI","id":"CVE-2026-44335","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":7.7,"headline":"PraisonAIAgents has SSRF and Local File Read via Unvalidated URLs in web_crawl Tool","id":"CVE-2026-40150","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":7.4,"headline":"PraisonAIAgents: Environment Variable Secret Exfiltration via os.path.expandvars() Bypassing shell=False in Shell Tool","id":"CVE-2026-40153","kev_date_added":null,"published":"2026-04-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-13","vendors":["MervinPraison"]},"summary":"Attackers can execute arbitrary OS commands via unsanitized input in memory hooks, potentially gaining full control of the host system.","url":"https://insights.sbomify.com/CVE-2026-40111/"}
