Packages
| Ecosystem | Package | Affected | Fixed in |

| Maven | org.apache.shenyu:shenyu | >= 2.4.0, < 2.4.3 | 2.4.3 |

Details
As written in the advisory (Markdown source, shown as plain text).
In Apache ShenYui, ShenYu-Bootstrap, RegexPredicateJudge.java uses Pattern.matches(conditionData.getParamValue(), realData) to make judgments, where both parameters are controllable by the user. This can cause an attacker pass in malicious regular expressions and characters causing a resource exhaustion. This issue affects Apache ShenYu (incubating) 2.4.0, 2.4.1 and 2.4.2 and is fixed in 2.4.3.
