GHSA-wmq2-jc9m-xp4m · Severity: medium · Ecosystem: maven — Cross-site Scripting in in JRuby
The regular expression engine in JRuby before 1.4.1, when $KCODE is set to 'u', does not properly handle characters immediately after a UTF-8 character, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted string.
Conclusion & alert: CVE-2010-1330 is rated High Exploit Risk (62.1/100): CVSS Medium severity, with medium exploitation likelihood (EPSS 2.22%). Core evidence: 1 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +1.79% 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.
