Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The ForgotLoginDetails resource in Atlassian Jira before version 7.6.6, from version 7.7.0 before version 7.7.4, from version 7.8.0 before version 7.8.4 and from version 7.9.0 before version 7.9.2 allows remote attackers to perform a denial of service attack via sending requests to it.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The ForgotLoginDetails resource in Atlassian Jira versions 7.6.5 and earlier, 7.7.0-7.7.3, 7.8.0-7.8.3, and 7.9.0-7.9.1 contains a vulnerability that allows remote attackers to cause denial of service by sending crafted requests to this endpoint, likely due to insufficient request handling or rate limiting.

MitigationUpgrade Jira to version 7.6.6, 7.7.4, 7.8.4, 7.9.2 or later. If immediate patching is not possible, consider temporarily restricting or rate-limiting access to the ForgotLoginDetails endpoint at the network level.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine installed Jira version
    Log into Jira as an administrator and navigate to the Administration > System > System Info page, or access /secure/AdminHome.jspa and locate the Jira version number displayed there.
    Affected if The displayed version is lower than 7.6.6, or falls within 7.7.0-7.7.3, 7.8.0-7.8.3, or 7.9.0-7.9.1.
  2. Identify ForgotLoginDetails endpoint availability
    Attempt to access the ForgotLoginDetails endpoint via a web request to a path such as /ForgotLoginDetails.jspa, /ForgotLoginDetails.jsp, or /plugins/servlet/forgotlogin (exact path varies by Jira deployment).
    Affected if The endpoint responds and is reachable from the network without authentication.
  3. Verify if the instance is exposed externally
    Review network configuration and firewall rules to determine whether the Jira web interface is accessible from untrusted networks or the public internet.
    Affected if Jira is exposed externally and the ForgotLoginDetails endpoint is reachable without authentication.
  4. Confirm vulnerability applicability
    Cross-reference the exact version identified in step 1 against the affected version ranges: < 7.6.6, 7.7.0-7.7.3, 7.8.0-7.8.3, or 7.9.0-7.9.1.
    Affected if The installed version matches any of these vulnerable ranges and the ForgotLoginDetails endpoint is accessible.

A user is affected if their Jira version falls within the vulnerable ranges AND the ForgotLoginDetails endpoint is accessible, allowing potential remote attackers to send crafted requests causing denial of service.
