An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-100373 exists.\n\nAffected product: open-metadata OpenMetadata. 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-2026-100373/ (Markdown: https://insights.sbomify.com/CVE-2026-100373/index.md)","id":"CVE-2026-100373","markdown":"https://insights.sbomify.com/CVE-2026-100373/index.md","name":"CVE-2026-100373","record":{"aliases":["GHSA-2qh3-cv3f-wh5h"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenMetadata","requires_auth":"high_privilege","summary":"Attackers with EventSubscription permissions can exploit SSRF to access internal networks and cloud metadata endpoints via webhook URL validation bypass.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"OpenMetadata through 2.0.2 contains a server-side request forgery vulnerability in the URLValidator.validateURL function that fails to properly resolve DNS hostnames and validate internal addresses.
