An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-72590 in the wild and no public exploit code.\n\nAffected product: alseambusher crontab-ui. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-72590/ (Markdown: https://insights.sbomify.com/CVE-2026-72590/index.md)","id":"CVE-2026-72590","markdown":"https://insights.sbomify.com/CVE-2026-72590/index.md","name":"CVE-2026-72590","record":{"aliases":["GHSA-25qx-69jj-jfcj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"crontab web UI","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary OS commands by injecting newlines into the env_vars parameter of the crontab-ui web interface.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"An OS command injection vulnerability in alseambusher/crontab-ui through 0.4.2 allows an unauthenticated remote attacker to inject arbitrary cron job entries by sending a crafted GET request to /crontab with URL-encoded newlines in the env_vars parameter.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"alseambusher crontab-ui - Unauthenticated RCE via Newline Injection in env_vars Parameter","id":"CVE-2026-72590","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Koito - Authenticated Server-Side Request Forgery via Album Image URL Parameter","id":"CVE-2026-72591"},"packages":[],"prev":{"headline":"alseambusher crontab-ui - Unauthenticated RCE via Shell Injection in Imported Database hook Field","id":"CVE-2026-72589"},"products":["crontab-ui"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["alseambusher"]},"summary":"Unauthenticated attackers can execute arbitrary OS commands by injecting newlines into the env_vars parameter of the crontab-ui web interface.","url":"https://insights.sbomify.com/CVE-2026-72590/"}
