A recently discovered vulnerability in Atlassian's Rovo assistant allows attackers to trick the tool into sending sensitive Jira and Confluence data to attacker-controlled servers. Organizations must review their settings and tighten permissions to mitigate this risk.
A recent discovery has revealed a previously unknown vulnerability in Atlassian's Rovo assistant, allowing attackers to send sensitive data from Jira and Confluence platforms to attacker-controlled servers. The vulnerability, dubbed "RovoBlast," was discovered by two security firms independently through different routes, with only one confirmed closed. The vulnerability can be triggered by hiding instructions in content that the assistant reads, leading to an indirect prompt-injection attack. Another route of exploitation involves manipulating the rovoChatPrompt parameter to exfiltrate sensitive data. The discovery highlights the importance of carefully reviewing permissions and configuring data access within Atlassian products. Organizations can take steps to mitigate this risk by reviewing app and group permissions, tightening underlying permissions, and avoiding treating web-search toggle as a complete security boundary.
A recent discovery has shed light on a previously unknown vulnerability affecting Atlassian's Rovo assistant, a tool designed to provide users with enhanced productivity and collaboration features within their Atlassian products. In an article published by The Hacker News, it was revealed that attackers can trick the Rovo assistant into sending sensitive data from Jira and Confluence platforms to attacker-controlled servers.
The vulnerability, dubbed "RovoBlast," was discovered independently by two security firms, PromptArmor and Varonis Threat Labs, through different routes. However, only one of these findings has been confirmed closed, with Atlassian having deployed a server-side fix on July 8, 2026. The other path is still unresolved, leaving organizations vulnerable to potential exploitation.
PromptArmor discovered that the RovoBlast vulnerability could be triggered by hiding instructions in content that the assistant reads. This led to the creation of an indirect prompt-injection attack, where attacker-controlled text was placed inside the content and treated as instructions. In this scenario, when a user uploaded a document carrying concealed injections and asked the Rovo assistant to organize their Jira tickets, it would search for the requested information, append what it found to an attacker's URL, open it, and deliver the data to the server.
Another route of exploitation was discovered by Varonis Threat Labs. According to their findings, the rovoChatPrompt parameter could carry a full prompt in a Rovo URL. This allowed attackers to put the path of an attacker-controlled image URL into the request and fetch the image, thereby exfiltrating sensitive data.
The discovery highlights the importance of carefully reviewing permissions and configuring data access within Atlassian products. The risk shown is not limited to data that a signed-in user can directly reach but also includes data that they can access through connected third-party apps.
PromptArmor noted that disabling web-search capabilities did not prevent its chain, as the assistant used separate URL-retrieval capabilities. This vulnerability has significant implications for organizations using Rovo, especially those with public websites enabled.
Atlassian's documentation allows administrators to block Rovo features for supported apps, thereby disabling current and upcoming AI features, including agents and chat. However, this may not provide adequate protection against the newly discovered vulnerability.
Organizations can take several steps to mitigate this risk. Firstly, they should review which apps and groups have access to Rovo's features and tighten underlying permissions. Secondly, they need to avoid treating the web-search toggle as a complete security boundary.
It is worth noting that neither disclosure reported evidence of the attacks being carried out against real organizations, but rather serves as an alert about potential vulnerabilities in the system. Given the nature of this vulnerability, it would be wise for affected parties to take immediate action to review and adjust their settings accordingly.
The RovoBlast vulnerability underscores the importance of continuous monitoring and awareness of emerging security threats within software applications. The discovery also highlights the need for organizations to stay informed about such vulnerabilities and take proactive measures to protect their systems from exploitation.
In conclusion, this recent vulnerability in Atlassian's Rovo assistant has significant implications for organizations using its features. While a server-side fix has been deployed by Atlassian, further vigilance is needed to ensure that this vulnerability does not become a source of exploited data for attackers.
