The setting that formats the log message emitted for API 4XX errors\nis an administrator-controlled Python format-string template that is rendered\nwith a live user object as an argument. Because Python string formatting permits\nattribute and item traversal on its arguments, an administrator can craft a\ntemplate that walks from the user object into the application settings and reads\nthe Django secret key and the database password. The formatted message is written\nto a logger that can be forwarded to an external log aggregator, whose destination\nis also administrator-controlled, allowing the secrets to be sent off the host. An\nauthenticated administrator can thereby obtain the master encryption key used to\nprotect all stored credentials and the database service password, enabling offline\ndecryption of every stored credential, forgery of user sessions, and direct\naccess to the controller database.","published":"2026-09-23T20:17:17.537","modified":"2026-09-24T14:51:56.593","cvss":{"score":8.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:71113"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:71114"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:71177"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:71179"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-84691"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527151"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-24T14:51:56.593"}}
