GHSA-6452-jr93-r5qm · Severity: high · Ecosystem: go — b3log Wide unauthenticated file access
b3log Wide before 1.6.0 allows three types of attacks to access arbitrary files. First, the attacker can write code in the editor, and compile and run it approximately three times to read an arbitrary file. Second, the attacker can create a symlink, and then place the symlink into a ZIP archive. An unzip operation leads to read access, and write access (depending on file permissions), to the symlink target. Third, the attacker can import a Git repository that contains a symlink, similarly leading to read and write access.
Conclusion & alert: CVE-2019-13915 is rated High Exploit Risk (76.3/100): CVSS High severity, with medium exploitation likelihood (EPSS 2.56%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +2.23% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
