To understand the payload, you first have to decode it. The sequences -3A and -2F are URL-encoded versions of a colon ( : ) and a forward slash ( / ). When decoded, the string looks like this: callback-url=file:///proc/self/environ
This is for any mainstream software framework, OAuth flow, or API endpoint. Instead, it is a path traversal / local file inclusion (LFI) payload designed to read sensitive process environment variables from a Linux-based system. callback-url-file-3A-2F-2F-2Fproc-2Fself-2Fenviron
The string callback-url=file:///proc/self/environ (or its URL-encoded variant %2E%2E%2F%2E%2E%2Fproc%2Fself%2Fenviron ) is a common attack signature indicating an attempt at or Server-Side Request Forgery (SSRF) to access sensitive system files.

Mira sat back. The words read like a poem coaxed from memory. The payload was an enigma left by someone who knew how to speak to machines and to people hiding behind them. The logs revealed a trail: a cluster of short-lived containers, each naming a letter of a phrase. Not an attack, not a hack—an artful breadcrumb trail. Instead, it is a path traversal / local
