Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45807 exists.\n\nAffected product: kestra-io kestra. 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-2026-45807/ (Markdown: https://insights.sbomify.com/CVE-2026-45807/index.md)","id":"CVE-2026-45807","markdown":"https://insights.sbomify.com/CVE-2026-45807/index.md","name":"CVE-2026-45807","record":{"aliases":["GHSA-3529-p4wf-xp79"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Kestra orchestration platform","requires_auth":"low_privilege","summary":"An authenticated user can read arbitrary files on the host filesystem via URL-encoded path traversal in Kestra API endpoints.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kestra","vendor":"kestra"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Kestra is an open-source, event-driven orchestration platform. Prior to 1.0.43 and 1.3.19, several Kestra API endpoints accept a kestra:// URI from the client and pass it through StorageInterface.parentTraversalGuard before reading the underlying file from the local storage backend. The guard only inspects the literal URI.toString(), so a URL-encoded .. written as %2E%2E slips through. The downstream code then calls URI.getPath(), which decodes %2E%2E back to .., and the resulting path is handed to Paths.get(...) without normalization. The OS resolves the .. segments at open(2) time, so an authenticated user with a single execution can read any file the Kestra process has access to on the host filesystem (/etc/passwd, mounted secrets, other tenants' execution outputs, etc.). This vulnerability is fixed in 1.0.43 and 1.3.19.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Kestra: Path traversal via URL-encoded \"%2E%2E\" in execution and namespace file endpoints allows arbitrary file read","id":"CVE-2026-45807","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"OpenBao's cross-namespace lease revocation via legacy sys/revoke path bypasses ACL","id":"CVE-2026-45808"},"packages":[],"prev":{"headline":"Penpot: Authenticated SSRF in remote image import via create-file-media-object-from-url","id":"CVE-2026-45806"},"products":["kestra"],"published":"2026-06-26","related":[{"cvss_score":10,"headline":"Kestra OSS OS Command Injection","id":"CVE-2026-49869","kev_date_added":"2026-09-02","published":"2026-06-26"},{"cvss_score":10,"headline":"Kestra: Unauthenticated RCE via /configs path-suffix auth-filter bypass","id":"CVE-2026-53576","kev_date_added":null,"published":"2026-06-26"},{"cvss_score":10,"headline":"Kestra: Remote Code Execution via SQL Injection","id":"CVE-2026-34612","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2026-38428","kev_date_added":null,"published":"2026-05-05"},{"cvss_score":8.7,"headline":"Kestra BasicAuth Password Stored as SHA-512 Enables Offline Brute-Force Attack","id":"CVE-2026-55069","kev_date_added":null,"published":"2026-06-26"},{"cvss_score":7.7,"headline":"Path traversal in kestra","id":"CVE-2026-49984","kev_date_added":null,"published":"2026-06-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-06-29","vendors":["kestra-io"]},"summary":"An authenticated user can read arbitrary files on the host filesystem via URL-encoded path traversal in Kestra API endpoints.","url":"https://insights.sbomify.com/CVE-2026-45807/"}
