The issue arises from an incorrect SUID (Set User ID) bit configuration in the binary, combined with the ability to control the input binary, allowing an attacker to execute an arbitrary binary with elevated privileges.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","score":6.7},"cwes":["CWE-269"],"references":["https://github.com/projectcalico/calico/issues/7981","https://github.com/projectcalico/calico/pull/8447","https://github.com/projectcalico/calico/pull/8517","https://www.tigera.io/security-bulletins-tta-2024-001/","https://github.com/projectcalico/calico/issues/7981"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-33522","score":0.0022,"percentile":0.12504,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6362-gv4m-53ww","url":"https://osv.dev/vulnerability/GHSA-6362-gv4m-53ww","summary":"Calico privilege escalation vulnerability","modified":"2026-09-10T03:49:18.745390132Z","packages":[{"ecosystem":"Go","name":"github.com/projectcalico/calico","purl":"pkg:golang/github.com/projectcalico/calico","ranges":["<3.26.5"],"fixed":["3.26.5"]},{"ecosystem":"Go","name":"github.com/projectcalico/calico","purl":"pkg:golang/github.com/projectcalico/calico","ranges":[">=3.27.0 <3.27.3"],"fixed":["3.27.3"]}]},{"id":"GO-2024-2801","url":"https://osv.dev/vulnerability/GO-2024-2801","summary":"Calico privilege escalation vulnerability in github.com/projectcalico/calico","modified":"2026-02-04T02:20:00.821558Z","packages":[{"ecosystem":"Go","name":"github.com/projectcalico/calico","purl":"pkg:golang/github.com/projectcalico/calico","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/projectcalico/calico/v3","purl":"pkg:golang/github.com/projectcalico/calico/v3","ranges":["all versions"],"fixed":[]}]}],"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).
