Researchers have reported a worrying class of issues around Rovo data theft: with attacker-controlled instructions, Atlassian’s AI assistant can be pushed to collect Jira or Confluence information that an authenticated user can access, then send it to an attacker-controlled endpoint. Importantly, the scenarios do not claim a full authorization bypass across a whole tenant—rather, they demonstrate how the assistant can turn permitted access into unintended data exfiltration.
Two separate security firms independently described ways to trigger the behavior. While one of the routes has a confirmed fix, the status of the other route was still uncertain at the time the related report was published.
What “Rovo data theft” looks like in practice
Both reports share a core theme: attacker-controlled content or parameters can influence what Rovo decides to fetch and where it sends the results. In each case, the attacker aims to get Rovo to output or retrieve data and then route it outward via a request controlled by the attacker.
Because Rovo operates within the permissions of the signed-in user, the risk is strongest for data that user can already access. That makes the problem less about breaking authorization and more about preventing the assistant from being used as a data “bridge” across products and connectors.
Two independent attack routes were found
Route 1: instructions hidden in content Rovo reads
PromptArmor, an AI security firm, described a chain where the attacker hides instructions inside content that Rovo is asked to use. The firm reported that uploading a file containing the concealed instructions was enough to make the assistant gather internal Jira or Confluence data and send it out via an attacker-controlled URL request, without a separate approval step.
In the example described by PromptArmor, a user uploads a document designed to carry a concealed injection and asks Rovo to organize Jira tickets. Rovo then searches Jira and Confluence as prompted, appends gathered information into a URL controlled by the attacker, and fetches it—allowing the attacker to retrieve the ticket and page contents from their own server logs.
PromptArmor also stated that when the victim later returns to the chat, the conversation may show suggested ticket updates but not obvious signs of exfiltration. However, the scenario was not presented as a true zero-click issue; the user still needs to expose Rovo to the poisoned content and make a normal request. PromptArmor’s narrower claim is that exfiltration does not require an additional human-in-the-loop approval step.
Further detail matters for orgs that rely on “web search” as a control. PromptArmor said its chain still worked when Rovo’s web-search option was switched off. The bypass was attributed to the use of a separate URL-retrieval capability rather than the web-search feature itself.
Route 2: attacker instructions preloaded through a Rovo link parameter
Varonis Threat Labs described a different path, which it called RovoBlast. Here, the attacker places instructions into a link by using a rovoChatPrompt URL parameter. The parameter is said to preload attacker instructions into the Rovo chat experience so that one click from an authenticated user can trigger Rovo to execute those instructions with the user’s privileges and then send results to an attacker-controlled server.
Varonis described a proof of concept that could lead Rovo to locate victim-accessible data, place the results into the path of an attacker-controlled image URL, and fetch that image—delivering data to the attacker’s server.
According to the disclosure record, the reporter demonstrated exfiltration of a private API key from Confluence. Bugcrowd further states that the one-click technique was tested against Jira and against data reachable through SharePoint and Outlook connectors.
What’s confirmed fixed—and what isn’t
Bugcrowd’s disclosure provides the clearer record of closure. The issue tied to the link-based technique was fixed server-side by Atlassian on July 8, 2026. The reporter validated the fix, and the Bugcrowd entry marks the problem resolved.
Two additional important details appear in the reporting:
- No CVE identifiers were assigned for either issue, and searches of major public vulnerability catalogs did not show entries as of August 8, 2026.
- No patching action is described for customers in the usual sense. The link route is already closed on Atlassian’s side, while the content-borne route depends heavily on scoping and configuration—such as which apps and groups can use Rovo.
For the PromptArmor content-borne path, the firm published its findings on August 5, 2026. It indicated the chain was still working at that time, including when web search was turned off. The report also notes that later remediation was not confirmed in the material provided. As a result, the status of that route after August 5 remains uncertain based on the information cited.
Why the web-search toggle isn’t a complete safety boundary
Atlassian offers web search for Rovo as an organization-level setting that can expand the assistant’s sources to public websites. PromptArmor argued that simply disabling that web-search option did not stop its demonstrated chain, because the outbound request relied on a different URL-retrieval capability.
This distinction raises an operational question for administrators: if the control only governs “web search,” it may not cover other fetch behavior the assistant can perform. The reporting also suggests an additional potential leakage method: Rovo can render Markdown images from model output, which could create other routes for data to leave. That said, the source material does not demonstrate a full chain exclusively through that rendering path for Rovo.
In short, treating the web-search setting as a standalone security boundary could create a false sense of protection.
Permissions matter: the risk is about what the assistant can reach
Rovo’s access is tied to the permissions configured in Jira, Confluence, and connected third-party apps. That means the demonstrations focus on information the signed-in victim already can access. The issue therefore behaves like an “assistant-to-exfiltration” problem: permitted data becomes reachable to an attacker through the assistant’s actions.
This framing matters for risk scoping. Instead of assuming the assistant bypasses authorization, organizations should treat the assistant as a powerful workflow tool that can move data along paths it was not intended to send externally—especially when prompts are attacker-controlled and when connected sources are in scope.
What admins can do now
Even with the link-based route reportedly fixed server-side, organizations still need to reduce the likelihood that attacker instructions can trigger unwanted data movement through Rovo. Based on the disclosures, the practical emphasis is on scoping and permissions.
Review which apps and groups can use Rovo
Atlassian documentation indicates that Rovo is enabled by default for supported plans (Standard, Premium, and Enterprise) and that organizations can manage access. Administrators can block Rovo features for supported apps, which disables current and upcoming AI features for that app, including Agents and Chat. In newer enterprise access experiences, Rovo can also be managed by app and user group.
One caveat is called out in Atlassian’s notes: on sites running multiple Jira-family apps, blocking one app does not necessarily remove shared capabilities. Features like Rovo Search, Chat, and Create with Rovo may remain available as long as any Jira app on the site still has Rovo enabled.
Tighten underlying permissions and connector scope
Because the assistant can only access data the user can reach, reducing what users can access—especially in connected systems—reduces the potential blast radius. Organizations should review connector availability and the permission model across Jira, Confluence, and third-party integrations such as those mentioned in the disclosures.
Additionally, do not assume that turning off web search alone closes the door. The reporting indicates that outbound requests can be driven by mechanisms beyond web search.
Has this been seen in the wild?
The source material states that neither disclosure reports evidence of either technique being used against a real organization. That is not the same as concluding no activity exists; it reflects what was contained in the two reports at the time they were published and validated.
Conclusion
The reports show how Rovo data theft can happen when attacker-controlled prompts or link parameters guide Atlassian Rovo to collect Jira/Confluence information and send it to an external destination. Fortunately, the link-based route has a confirmed server-side fix from July 8, 2026, and Bugcrowd marks it resolved. At the same time, the content-borne route described by PromptArmor was still reported as working when it was published on August 5, 2026, with remediation status not confirmed in the cited material.
For administrators, the clearest next step is to tighten scoping: review which apps and groups can access Rovo, reduce permissions and connector reach, and treat the web-search toggle as an incomplete safeguard rather than a comprehensive security boundary.
