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-2026-19503 in the wild and no public exploit code.\n\nAffected product: MongoDB Atlas SQL ODBC Driver. 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-2026-19503/ (Markdown: https://insights.sbomify.com/CVE-2026-19503/index.md)","id":"CVE-2026-19503","markdown":"https://insights.sbomify.com/CVE-2026-19503/index.md","name":"CVE-2026-19503","record":{"aliases":["GHSA-gxxm-9rmv-h4mp","UBUNTU-CVE-2026-19503"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"MongoDB ODBC Driver","requires_auth":"none","summary":"Attackers can trigger local protocol handlers via malicious OIDC endpoints, potentially exposing credentials or executing code in the user's context.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[{"product":"odbc_driver","vendor":"mongodb"},{"product":"sql_schema_builder_cli","vendor":"mongodb"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"MongoDB Schema Manager and MongoDB Atlas SQL ODBC Driver do not validate the scheme of the authorization and token endpoints returned by an OIDC issuer's discovery document.
