DescriptionCVE.org

JimuReport contains an authentication bypass vulnerability in the report folder template listing endpoint that allows unauthenticated attackers to enumerate all reports and retrieve share tokens. Attackers can use disclosed share tokens to access protected report endpoints and retrieve full report definitions including embedded SQL statements and live query data.

AnalysisAI

Unauthenticated access to JimuReport's report folder template listing endpoint exposes all report definitions, share tokens, embedded SQL statements, and live query data to any remote attacker. The CWE-306 root cause - missing authentication for a critical function - means the disclosure requires no credentials, no user interaction, and no special tooling. …

Vulnerability AssessmentAI

Exploitation No special conditions are required beyond network reachability to the JimuReport web application. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) is internally consistent with the description: network-reachable, low complexity, zero prerequisites, high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An external attacker sends an unauthenticated HTTP GET request to JimuReport's report folder template listing endpoint, receiving a response containing report names, folder structures, and share tokens. The attacker then uses the disclosed share tokens to authenticate to protected report endpoints, downloading full report definitions - including embedded SQL queries that may expose database schema, table names, and production data - without ever obtaining valid user credentials.
Remediation No vendor-released patch has been identified at time of analysis; the vulnerability is disclosed via GitHub issue https://github.com/jeecgboot/jimureport/issues/4695, which should be monitored for an upstream fix. … Detailed patch versions, workarounds, and compensating controls in full report.
