This could allow network masks to accept larger networks.\n\nLeading zeros were also accepted, but treated as decimal instead of octal.  This could lead to confusion about what networks are acceptable.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":7.3},"cwes":["CWE-1289"],"references":["https://metacpan.org/release/RRWO/Net-CIDR-Set-0.21/changes","https://nvd.nist.gov/vuln/detail/CVE-2025-40911","https://nvd.nist.gov/vuln/detail/CVE-2026-45191"],"products":["rrwo:net\\"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-49942","score":0.003,"percentile":0.2278,"date":"2026-10-31"},"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).
