Network-reachable API, low complexity, but PR:L because attacker needs an authenticated log:view account; replayed session tokens grant full account control, so C/I/A all High with no scope change.

admin3 through 3.0.0 persists user session tokens in the audit log event body when publishing UserLoggedIn domain events. Attackers with log:view permission can read the JSON response from the GET /logs endpoint to harvest session tokens and replay them as bearer credentials for full user access.
AnalysisAI
Session token harvesting in cjbi admin3 through version 3.0.0 lets any authenticated account holding the log:view permission read bearer credentials out of the audit-log event body returned by GET /logs. Because the UserLoggedIn domain-event handler writes the user's live session token into the logged event JSON, an attacker who opens the log-viewing screen can extract tokens belonging to other users - including administrators - and replay them as bearer credentials for full account takeover, yielding high confidentiality, integrity, and availability impact (CVSS 8.7). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated account holding the log:view permission on an admin3 instance at version 3.0.0 or earlier; that account calls the GET /logs endpoint and reads session tokens that the UserLoggedIn domain-event handler writes into the audit-log event body, then replays them as bearer credentials. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine, above-average priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch was identified in the provided intelligence, so remediation must initially be configuration- and code-level. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all cjbi admin3 deployments and confirm whether any instance is running version 3.0.0 or earlier; immediately revoke the log:view permission from every account that does not have an absolute operational need for it, restrict the permission to a small named set of trusted administrators, and block or blackhole external and non-administrative network access to the GET /logs endpoint at the reverse proxy, WAF, or load balancer. …
