In affected versions this vulnerability allows an authenticated but unprivileged user to use the REST API to capture and download packets with no capture filter and without adequate permissions. This is important because the capture filters can effectively limit the scope of information that a user can see in the data captures. If no filter is present, then all data on the local network segment where the program is running can be captured and downloaded. v3.12 fixes this problem. There is no workaround, you must upgrade to v3.12 or greater.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-754","CWE-287"],"references":["https://github.com/jdhwpgmbca/pcapture/commit/0f74f431e0970a2e5784dbd955cfa4760e3b1ef7","https://github.com/jdhwpgmbca/pcapture/issues/7","https://github.com/jdhwpgmbca/pcapture/security/advisories/GHSA-3r67-fxpr-p2qx","https://github.com/jdhwpgmbca/pcapture/commit/0f74f431e0970a2e5784dbd955cfa4760e3b1ef7","https://github.com/jdhwpgmbca/pcapture/issues/7"],"products":["pcapture_project:pcapture"],"source":"nvd","synced_at":"2026-10-19T21:21:57.125947417+00:00"},"epss":{"cve":"CVE-2021-39196","score":0.01252,"percentile":0.69443,"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).
