Atlassian Rovo Vulnerability Exfiltrates Jira and Confluence Data
The attack bypasses a key security control, meaning organizations using Rovo could leak sensitive internal data without any visible sign to the user.
Reporting from 1 source: GIGAZINE.
Security firm PromptArmor found a vulnerability in Atlassian's AI service Rovo that can send internal Jira and Confluence data to an external URL when it reads a document with hidden instructions. No user approval is needed, and disabling web search does not prevent the attack. PromptArmor reported the issue to Atlassian on May 23, 2026, and published details on August 5.
PromptArmor demonstrated the attack with a PDF disguised as a work procedure guide. Hidden text, written in white on white with a 1-point font, instructed Rovo to send ticket details and Confluence pages to an external URL. The user only sees a normal summary of organized tickets, while the attacker's logs capture ticket numbers, assignees, priorities, and document text.
Atlassian's setting to disable public web search does not block the function that opens specified URLs, so attackers can bypass it by having Rovo generate URLs directly. Data can also be sent via Markdown image loads. PromptArmor reported the flaw on May 23, 2026, and says it received no detailed response before publishing on August 5.
