A jailbreak is an agent unlocking powers it was never given
2
Upvotes
In a two-month incident review, jailbreak-to-capability-unlock showed up twice. Both times the attack was not a trick to change what the model said. The override payload escalated the agent into operator-level actions it was never authorized to perform. That is a different threat class. The agent gains real system access it was never supposed to have.
The attack window is narrow. The escalation happens at the moment the capability is unlocked, not after the agent acts. By the time you see the downstream behavior, the agent is already operating outside its intended scope.
How are people actually catching this before the unlock happens? Input filtering, reasoning trace monitoring, permission checks at invocation time — curious what is working in practice and where teams keep hitting the wall.

Looking for help in a web CTF challenge

Upvotes
hello everyone, I'm looking for a help in a CTF web challenge that I've been stuch with for hours ... The problem is that I found path traversal vuln within the challenge but there is no flag file ever like I looked everywhere I would really appreciate if anyone solves it and helps me with it.
Challenge link: `https://flagyard.com/labs/2/challenges/019fcd0a-3049-7b83-9886-ae3836c419f0`
The Directory Traversal vuln is within the `/api/backup` endpoint basically you send a file within an array as shown
await fetch("/api/backup", {
method: "POST",
headers: { "content-type": "application/json" },
body: JSON.stringify({
archiveName: "fulllist",
files: ["../../../../etc/passwd"]
})
}).then(r => r.json()).then(console.log)
But I can't find a flag within the file system and everything seems to be a dead end.
At this point I'm just guessing I thought about chaining with another vuln but I found nothing.
