Subsequent reuse of this handle triggers an immediate crash, and\ncloning it via `curl_easy_duphandle()` copies this corrupted state into the\nduplicate. If the original handle is subsequently freed, executing a transfer\non the cloned handle causes a heap use-after-free read against the dangling\nhandle reference; alternatively, reusing the original or cloned handle while\nchanging only  `CURLOPT_WRITEDATA` (and omitting `CURLOPT_WRITEFUNCTION`)\nresults in type confusion, forcing the internal parser to interpret incoming\nserver response bytes into memory at the application-supplied write data\npointer.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://curl.se/docs/CVE-2026-92388.html","https://curl.se/docs/CVE-2026-92388.json","https://hackerone.com/reports/4022070"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-92388","score":0.00212,"percentile":0.11347,"date":"2026-10-25"},"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).
