A path composed with that operator discards the left operand when the right one is absolute and follows parent references otherwise, so a filename such as ../../../tmp/x or /tmp/x resolves outside the intended directory; nothing canonicalises the result, checks that it remains under the upload root, or prevents a .py suffix. The route's only dependency is get_user_from_headers in dbgpt_serve/utils/auth.py, which returns a request carrying the admin role whether or not a user_id header is supplied, so the endpoint is reachable without credentials. A remote attacker holding no account can therefore write attacker-controlled bytes to any path the server process can write, place a new Python module inside the application package or replace one the application already imports, and obtain code execution in the server process when that module is next imported." } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "cweId": "CWE-22", "description": "Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')", "type": "CWE" } ] } ], "affected": [ { "vendor": "eosphoros-ai", "product": "DB-GPT", "collectionURL": "https://github.com/eosphoros-ai/DB-GPT", "repo": "https://github.com/eosphoros-ai/DB-GPT", "packageURL": "pkg:pypi/dbgpt-app", "defaultStatus": "unaffected", "versions": [ { "version": "0.8.0", "lessThan": "0.8.1", "status": "affected", "versionType": "semver" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:dbgpt:db-gpt:*:*:*:*:*:*:*:*", "versionStartIncluding": "0.8.0", "versionEndExcluding": "0.8.1" } ] } ] } ], "metrics": [ { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV4_0": { "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "HIGH", "subConfidentialityImpact": "NONE", "vulnIntegrityImpact": "HIGH", "subIntegrityImpact": "NONE", "vulnAvailabilityImpact": "HIGH", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "CRITICAL", "baseScore": 9.3, "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N" } }, { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV3_1": { "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "version": "3.1", "baseSeverity": "CRITICAL", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H" } } ], "references": [ { "url": "https://github.com/eosphoros-ai/DB-GPT", "tags": [ "product" ] }, { "url": "https://github.com/eosphoros-ai/DB-GPT/blob/v0.8.0/packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/agentic_data_api.py", "tags": [ "technical-description" ] }, { "url": "https://github.com/eosphoros-ai/DB-GPT/releases/tag/v0.8.1", "name": "DB-GPT v0.8.1 Release Notes", "tags": [ "release-notes" ] }, { "url": "https://pypi.org/project/dbgpt-app/", "tags": [ "product" ] }, { "name": "VulnCheck Advisory: DB-GPT 0.8.0 Path Traversal Arbitrary File Write via Skill Upload Filename", "tags": [ "third-party-advisory" ], "url": "https://www.vulncheck.com/advisories/db-gpt-0.8.0-path-traversal-arbitrary-file-write-via-skill-upload-filename" } ], "credits": [ { "lang": "en", "value": "Abhinav Jaswal", "type": "finder" } ], "x_generator": { "engine": "vulncheck-endgame" }, "source": { "discovery": "UNKNOWN" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-08-28T22:36:32.611124Z", "id": "CVE-2026-80104", "options": [ { "Exploitation": "none" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-08-28T22:36:49.668Z" } } ] } }
