CVE-2022-22978
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn spring security versions prior to 5.4.11+, 5.5.7+ , 5.6.4+ and older unsupported versions, RegexRequestMatcher can easily be misconfigured to be bypassed on some servlet containers. Applications using RegexRequestMatcher with `.` in the regular expression are possibly vulnerable to an authorization bypass.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceRegexRequestMatcher in Spring Security has a regex bypass vulnerability when `.` is used in the pattern. The `.` metacharacter can match different characters depending on servlet container behavior, allowing attackers to bypass authorization checks by crafting requests that match the flawed regex pattern.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Spring Security versionLocate the spring-security-core jar file in your project dependencies (check pom.xml, build.gradle, or the actual jar filename). Extract the version number from the filename or dependency declaration.Affected if The version is less than 5.4.11, or between 5.5.0 and 5.5.6 inclusive, or between 5.6.0 and 5.6.3 inclusive, or all versions of Netapp/Oracle products listed.
-
Find RegexRequestMatcher usage in security configurationSearch your codebase for imports and usages of org.springframework.security.web.util.matcher.RegexRequestMatcher. Check Java configuration files (often in a config package), XML security configuration files (typically spring-security.xml or similar), or annotation-based configurations using @RequestMatcher.Affected if RegexRequestMatcher is found in your security configuration code.
-
Inspect regex patterns for unescaped dot metacharacterLocate all RegexRequestMatcher constructor calls and examine the pattern string argument. Look for instances where a literal dot (.) appears in the pattern without being escaped as \. or being part of a character class like [.]Affected if The pattern contains any unescaped . metacharacters that could match unexpected characters depending on servlet container behavior.
-
Verify authorization rules use RegexRequestMatcherExamine the security filter chain configuration to determine which endpoints or URL patterns are protected by RegexRequestMatcher rules. Look for any antMatchers().regexMatchers() or RegexRequestMatcher references in your HttpSecurity or WebSecurityConfigurerAdapter configuration.Affected if RegexRequestMatcher is used to protect sensitive endpoints or enforce authorization rules.
You are affected if your Spring Security version is vulnerable AND your configuration uses RegexRequestMatcher with unescaped dot characters in patterns protecting sensitive resources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped5.5.75.6.4
Upgrade Spring Security to version 5.4.11+, 5.6.4+, or later. Additionally, review and harden all RegexRequestMatcher configurations by escaping `.` as `\.` or using more specific character classes.
Spring Security 5.6.4 (or minimum 5.5.7 or 5.4.11 depending on branch)
- Identify the current Spring Security version in the project's dependency management (e.g., pom.xml, build.gradle)
- Upgrade Spring Security to version 5.6.4 or later (or 5.5.7+ or 5.4.11+ depending on your branch)
- After upgrade, review all RegexRequestMatcher configurations and ensure any literal `.` characters in regex patterns are escaped as `\.` to prevent matching any character
- Rebuild the application and run all authorization-related tests
- Verify that the authorization rules using RegexRequestMatcher are functioning correctly and cannot be bypassed
