Cross Site Scripting vulnerability in xxl-job-admin v.3.0.0 allows a remote attacker to execute arbitrary code via a crafted HTTP GET request containing a malicious script
AnalysisAI
Reflected Cross-Site Scripting in xxl-job-admin v.3.0.0 allows a remote unauthenticated attacker to execute arbitrary JavaScript in a victim's browser by tricking an authenticated user into clicking a crafted HTTP GET request containing an unsanitized malicious script payload. The vulnerability carries a CVSS 3.1 score of 6.1 with Scope Changed, indicating the injected script can affect browser-level resources beyond the immediate application context, enabling session hijacking, credential theft, or redirection against admin-level users. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim is an authenticated xxl-job-admin user with an active browser session, and that the attacker can deliver a crafted URL to that user (e.g., via phishing or a malicious link on a page the admin visits). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.1 score reflects a medium-severity reflected XSS with UI:R and S:C. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a URL targeting the vulnerable xxl-job-admin endpoint with a malicious JavaScript payload embedded in a GET parameter, then delivers it to an authenticated admin user via phishing email or instant message. When the admin clicks the link and their browser renders the unsanitized response, the injected script executes in the admin's session context, silently exfiltrating session cookies or CSRF tokens to an attacker-controlled server. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the provided references do not include an official xxl-job vendor advisory or patched release version. … Detailed patch versions, workarounds, and compensating controls in full report. |
