- Exploitation

ANSSI-CERT-FR issued an advisory covering a large batch of vulnerabilities affecting Atlassian's Data Center product line, including Confluence Data Center, Jira Software Data Center, and Jira Service Management Data Center. The disclosed flaws span a wide range of impact types including remote code execution, privilege escalation, denial of service, data integrity and confidentiality breaches, security policy bypass, and server-side request forgery (SSRF). The advisory references over 40 individual CVEs tied to more than 50 separate Atlassian security bulletins published on 21 July 2026.
No evidence of active exploitation is mentioned in the advisory, and no threat actor, malware, or campaign is associated with this disclosure. Organizations running affected versions of Confluence Data Center (prior to 10.2.14 or 9.2.22) or Jira Software/Service Management Data Center (prior to the respective patched versions) should apply vendor-supplied patches referenced in the accompanying Atlassian bulletins to mitigate risk, particularly given the presence of remote code execution vectors among the disclosed issues.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
