This allows attackers to cause a Denial of Service (DoS) via a crafted input to the 'RemoveUnnecessaryFirstRow', it will check the expression between 'Agg' and 'GroupBy', but does not check the return type. NOTE: PingCAP disputes this, arguing that reproduction did not cause the security impact of service interruption to other users. They maintain it is a complex query bug in the product but not a DoS.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-400"],"references":["https://gist.github.com/ycybfhb/4aa6809695b9e8a1cd1429e597c17517","https://github.com/pingcap/tidb/issues/53733"],"products":["pingcap:tidb"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-41434","score":0.00414,"percentile":0.357,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
