CVE-2026-19756: Path Traversal in Dromara lamp-cloud
CVE-2026-19756 is a path traversal vulnerability in Dromara lamp-cloud up to version 5.10.0. It affects the Code Generator component, specifically the DefGenProjectController.java file, where manipulation of the outputDir, parent, or projectPrefix arguments can lead to unauthorized file system access. The vulnerability can be exploited remotely. The issue was reported to the project early, but no response or fix has been issued yet. The CVSS score is 5.3, indicating medium severity.
AI Analysis
Technical Summary
This vulnerability in Dromara lamp-cloud (versions 5.0 through 5.10.0) involves improper handling of certain input parameters (outputDir, parent, projectPrefix) in the Code Generator component's DefGenProjectController.java file. This allows an attacker to perform path traversal attacks remotely, potentially accessing or manipulating files outside the intended directories. The vulnerability has been publicly disclosed, but no official remediation or patch has been provided by the vendor as of the publication date.
Potential Impact
Successful exploitation allows an attacker to traverse directories on the server hosting lamp-cloud, potentially accessing sensitive files or causing unintended file operations. The impact is limited by the medium CVSS score and the requirement for low privileges (PR:L). There is no evidence of active exploitation in the wild.
Mitigation Recommendations
No official fix or patch is currently available from the vendor. Users should monitor the vendor's advisories for updates. Until a patch is released, consider restricting access to the affected component and validating or sanitizing inputs related to outputDir, parent, and projectPrefix parameters to mitigate exploitation risk.
