Description

Red Hat has issued a security advisory for dogtag-pki, an enterprise Public Key Infrastructure (PKI) management system. The update addresses three vulnerabilities: a decompression-bomb denial of service in RESTEasy's IIOImageProvider (CVE-2026-89059), a Cross-Origin Resource Sharing (CORS) filter misconfiguration allowing reflection of arbitrary origins with credentials under wildcard settings (CVE-2026-89058), and a denial of service via regular expression backtracking in Jackson-core (CVE-2026-89407). These issues affect components of the dogtag-pki system used in Red Hat Enterprise Linux 10 and related variants. The advisory rates the impact as Important and provides updated packages to remediate these vulnerabilities.
