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-2026-15925 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- snowflake-connector-python (PyPI): affected all versions; fixed in 3.18.1, 4.7.1\n- snowflake-connector-python (PyPI): affected all versions; fixed in 3.18.1\n- snowflake-connector-python (PyPI): affected all versions; fixed in 3.18.1\n- snowflake-connector-python (PyPI): affected from 4.0.0; fixed in 4.7.1\n- snowflake-connector-python (PyPI): affected from 4.0.0; fixed in 4.7.1\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-2026-15925/ (Markdown: https://insights.sbomify.com/CVE-2026-15925/index.md)","id":"CVE-2026-15925","markdown":"https://insights.sbomify.com/CVE-2026-15925/index.md","name":"CVE-2026-15925","record":{"aliases":["ECHO-5d7e-7246-3bf5","GHSA-5cc2-282f-jjq2","MINI-3jv6-9prf-r77c","MINI-68wg-3982-cwc2","MINI-9639-6749-3cr8","MINI-jpgj-j4cq-c62x","PYSEC-2026-3920"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Snowflake Python connector","requires_auth":"none","summary":"An on-path attacker can bypass TLS hostname verification to intercept credentials and data or execute SQL via the Snowflake Python connector.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SNOWFLAKE","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"}],"description":"Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this by intercepting or redirecting network traffic and presenting a certificate signed by any trusted CA for any domain, causing the connector to accept connections without validating that the certificate matched the requested hostname. Successful exploitation requires an on-path traffic interception capability (e.g. ARP/DNS poisoning, rogue access point, BGP hijacking, or malicious proxy/exit node). This vulnerability may have exposed credentials, query data, and staged file contents to interception and tampering, and may have enabled the attacker to issue arbitrary SQL within the context of the victim's connector session. Impact is limited by the privileges of the affected Snowflake role. The fix is available in Snowflake Connector for Python versions 4.7.1 and 3.18.1.
