Published Sep 15, 2026 CVSS 3.1 · 2.7 Low EPSS < 1% KEV · Not listed
Description
An issue was discovered in Keyfactor SignServer before 7.6.0. The output file to which SignerStatusReportWorker logs the report can be set to any path, even one that points to a file that already exists. This gives a user (with admin access) the possibility to write files in arbitrary directories in the server filesystem and potentially overwrite files accessible by the local user JBoss.
