CVE-2022-26135Network attack vector

Authenticated full-read SSRF via batch endpoint

Published Jun 30, 2022 · Updated Oct 29, 2024

Authentication bypass in Atlassian Jira Server and Data Center Mobile Plugin before fixed releases allows remote authenticated users to read server-side resources via a batch endpoint. The batch request handler accepts attacker-controlled destinations and performs server-side requests without restricting internal targets, creating full-read SSRF. A Jira account, including a self-registered account when sign-up is enabled, is required; the documented impact is confidentiality loss without reported integrity or availability impact.
