When the SECURITY_SCANNER_V4_PSK (pre-shared key) is not set, a remote unauthenticated attacker can send POST requests to the security scanner notification endpoint. This allows the attacker to flood the notification queue and inject path traversal characters into Clair API URL paths. The primary consequence is worker resource exhaustion and blind path manipulation on the configured Clair host, potentially leading to a denial of service.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","score":8.2},"cwes":["CWE-306"],"references":["https://access.redhat.com/security/cve/CVE-2026-74243","https://bugzilla.redhat.com/show_bug.cgi?id=2516142"],"products":["redhat:openshift_update_service","redhat:quay"],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74243","score":0.00463,"percentile":0.40182,"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).
