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-2026-4503 in the wild and no public exploit code.\n\nAffected product: IBM Langflow Desktop. 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-2026-4503/ (Markdown: https://insights.sbomify.com/CVE-2026-4503/index.md)","id":"CVE-2026-4503","markdown":"https://insights.sbomify.com/CVE-2026-4503/index.md","name":"CVE-2026-4503","record":{"aliases":["GHSA-f8v3-8wm7-h9qr"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Langflow Desktop","requires_auth":"none","summary":"Unauthenticated attackers can view other users' images via an insecure direct object reference in the image download endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"langflow_desktop","vendor":"langflow"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"IBM Langflow Desktop 1.0.0 through 1.8.4 Langflow could allow an unauthenticated user to view other users' images due to an indirect object reference through a user-controlled key.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Unauthenticated Insecure Direct Object Reference (IDOR) Vulnerability in Langflow Desktop Image Download Endpoint","id":"CVE-2026-4503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"eosphoros-ai db-gpt Incomplete Fix editor sql injection","id":"CVE-2026-4504"},"packages":[],"prev":{"headline":"Arbitrary File Write and Remote Code Execution Vulnerability in Langflow v2 API","id":"CVE-2026-4502"},"products":["Langflow Desktop"],"published":"2026-04-30","related":[{"cvss_score":8.8,"headline":"Authenticated Remote Code Execution Vulnerability in Langflow Code Validation Endpoint","id":"CVE-2026-6543","kev_date_added":null,"published":"2026-04-30"},{"cvss_score":6.5,"headline":"Server-Side Request Forgery (SSRF) in Langflow URL Component","id":"CVE-2026-3340","kev_date_added":null,"published":"2026-04-30"},{"cvss_score":6.5,"headline":"Path Traversal and Arbitrary File Write Vulnerability in IBM Langflow Desktop API v2 File Upload Endpoint","id":"CVE-2026-3345","kev_date_added":null,"published":"2026-04-30"},{"cvss_score":6.5,"headline":"Arbitrary File Write and Remote Code Execution Vulnerability in Langflow v2 API","id":"CVE-2026-4502","kev_date_added":null,"published":"2026-04-30"},{"cvss_score":6.4,"headline":"Stored Cross-Site Scripting (XSS) in Langflow Markdown Rendering via rehypeRaw","id":"CVE-2026-3346","kev_date_added":null,"published":"2026-04-30"},{"cvss_score":5.4,"headline":"IBM Langflow Desktop 1.0.0 - 1.9.2 DNS Rebinding Bypasses SSRF Protection Allowing Access to Internal Services","id":"CVE-2026-3341","kev_date_added":null,"published":"2026-06-11"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-12","vendors":["IBM"]},"summary":"Unauthenticated attackers can view other users' images via an insecure direct object reference in the image download endpoint.","url":"https://insights.sbomify.com/CVE-2026-4503/"}
