Aias00 opened a new issue, #6770:
URL: https://github.com/apache/shenyu/issues/6770
- severity: Medium
- files:
`shenyu-plugin/shenyu-plugin-logging/shenyu-plugin-logging-desensitize-api/.../matcher/KeyWordMatch.java:36-46`
- description: The constructor iterates over the keyword set and appends
each keyword directly into a regex `StringBuilder` without escaping:
`sb.append(tempKeyWord)`. If any keyword contains regex metacharacters (`(`,
`[`, `.`, `*`, `\`, `+`, `?`, `{`, `|`), `Pattern.compile` throws
`PatternSyntaxException`. This propagates from
`AbstractLoggingPlugin.doExecute()` line 119.
- impact: A single misconfigured keyword containing regex metacharacters
breaks all request handling for every request matching that rule.
- suggested_fix: Use `Pattern.quote(tempKeyWord)` to escape each keyword
before appending.
- confidence: High
- related_existing: none
