> Rovo's URL retrieval tool is insecure: there are no protections against opening a URL that has been dynamically created by the agent. Here, Rovo is manipulated to append sensitive data to an attacker's URL. When Rovo calls the insecure tool to open the URL, the attacker's site logs the request, including the appended sensitive data.
Atlassian has gone from a trusted enterprise-partner to a complete shit-show in just 18 months. This surprises nobody. There will be classes taught in how to fuck up a good business and Atlassian will be the prime example.

I can’t get over how bad “Rovo” is. Somehow more aggressive and useless than Microsoft putting “Copilot” everywhere.
It’s objectively worse than using something like Cowork + MCP, AND they injected it into every single page on JIRA and Confluent which has made web browsing way slower while all the junk is loading.
I hate it, they've just gone and smooshed a bunch more AI crap into Jira too in the last few days.
Useless buttons to "suggest subtasks" and "improve issue" and offer to write the description. Absolutely useless nonsense, I wish I could turn it all off and there is an issue on their bug tracker with that request (turning it off as an individual user), and it has many votes, but at the moment you can only disable it globally as admin.
I just asked it to do a summary or a status page for my staff so I can share the high level details. Somehow it retrieved a version of the page from two weeks ago and summarised that. When I said, this is old, it happily said, yep, I'll do a summary of the current page. I kinda feel there may be people in between the box and some lame LLM.
Our PM trialed it for writing user stories and most of it was “ticket description but as gherkin stories” which is good, but it made like 2-3 stories referencing a data structure and fields we were not planning on whatsoever - idek where it got the idea from, none of what it wanted to do was covered _anywhere_
Rovo makes for an INCREDIBLE time reading jira tickets and confluence pages. Someone wrote YES in all caps in a page ? Rovo will helpfully tell you (after loading for 5 seconds) that YES stands for Yassified Entertainment Setting, a new option added to the app in January 2024.
Whenever I feel like I'm bad at software development, I look at Atlassian and I feel good.
I feel like prompt armor writes the exact same blog post for every agentic tool because they all suffer from the ignore previous instructions prompt injections.
Rovo is funny. It downloads everything it can do Atlassian servers for "analysis". And you're pretty much screwed if you link it to Google Docs or Sharepoint. How do I know this? "Why is an AWS IP downloading all our docs?" question I got about a month ago.
> Note: This attack succeeds even if an organization has disabled web search for Rovo. This is because the web search setting fails to remove the tool for opening the search results.
Wow, great work Atlassian. The web search setting does not disable web search.
It's kind of sad because in a shitty Jira setup, Rovo is usually the only way to make any sense of tickets. Don't ask me how I know this. Sadly I think many teams have become dependent on the tool to make sense of their dumpster fire of an Atlassian environment (usually by their own doing but anyway).

I think it was Anthropic that first introduced a pattern that completely locks this down: your URL retrieval tool should only work for URLs that have previously been typed into the conversation by a user or have been returned from a trusted tool.
If the agent itself concatenates a new URL together - with leaked data after a ? - you should block that from being fetched.
The great thing about this solution is it's deterministic. You don't need any extra AI in the max - you implement a URL fetching system that knows which sources it should check for a direct match on the URL before it makes that GET request.
> If the agent itself concatenates a new URL together - with leaked data after a ? - you should block that from being fetched.
You're correct of course, I just want to note that the exfiltrated data could be in any part of the URL, so the absence of a query string doesn't indicate that no payload has been encoded into the URL. Arbitrary example, you can include credentials in a URL, so you could encode the exfiltrated data into a password.
One of the latest mitigations is to make sure that a URL an agent visits has been indexed by a search engine crawler. At least that is what OpenAI does now in ChatGPT.
That makes sure that not a large amount of private data is leaked in one request. Assuming that if a URL is indexed, it is public data. However, there are still bypasses with using many requests to leak information, like a request per character of pre-indexed URLs.
I have some demos of doing that on my blog, but it makes it more involved for an attacker. And that could also be detected. Still not perfect, but a solid improvement, for a generic agent like ChatGPT.
It's not a 100% bullet proof approach either, but pretty good.
Regarding the point on using URLs returned from trusted tool calls. That is similar to using pre-indexed URLs: If a "trusted tool" includes things like read a document, read an email,... an attacker can return a large list of afterwards "safe" urls, like 26 to cover A-Z. And then an attack can render many requests, e.g. character by character. But, again, similar to the pre-indexing, things are getting more a lot more expensive for an attacker that way. However, still not impossible.
For agents that have a specific purpose simple domain allow-listing is also a pretty effective idea in to prevent attacker controlled endpoints.
Rovo is one of those intrusive AI buttons that suddenly appeared everywhere without any warning. Its so annoying having already shitty UI get borked with features I never use. Almost as annoying as Whatsapp suddenly getting the same FOMO AI button. Its not like I need an AI agent to talk to friends and family. And a summary is something I can always generate via copy&paste into CLI chat session.
I'm still on the edge about security as an afterthought in LLMs. Given its now so easy to generate a ton of slop - why not focus on nonfunctional stuff making LLMs operate faster than thinking for X minutes and limiting exfiltration of local env secrets?
I find it difficult to be impressed by "prompt injection" attacks that require the victim to enter the malicious prompt themselves --- like, really? If you tell Rovo to exfiltrate your data, it'll do it?
Obviously, there should be URL protection rules to control what it can access, but this requires a very specific and unlikely set of circumstances to exploit.
The writing is rather low quality, but seems to be consistent with their other posts.
Maybe to give credit they are being purposefully vague about details to avoid giving away the bait but still seem like you could give me details without literally copy and pasting the attack.
It's incredibly hard to block all rovo on Atlassian pages. I tried adblock, it failed, I settled for the custom chrome plugin. And yet, every once a while a new way to disturb my peace shows it ugly head.
So why intentional, again? Because it's impossible to disable it until you have a very certain, very expensive plan.
I hate working with Atlassian, years and years ago moved to youtrack instead of Jira mainly because it handles teams who work on multiple projects way better. But confluence remains, just need to spend some time re-evaluating other wikis (there's always been some blocking reason why the alternatives aren't a good fit, but they've all improved a lot)

I've been looking at switching to Notion and Linear, but just haven't had the time to complete evaluation.

Yeah this attack is possible on all modern agentic systems.
* Access to your private data
* Exposure to untrusted content
* The ability to externally communicate in a way that could be used to steal your data

And blocking it wholesale reduces usefulness of the agent so it is a tradeoff.

There is paper OpenAI wrote a few months ago that explains how they do it: https://embracethered.com/blog/posts/2026/data-exfiltration-...
