GHSA-R5W3-XV2F-J59Q Spring Framework Algorithmic Denial of Service via SpEL Expressions

Applications that evaluate user-supplied Spring Expression Language SpEL expressions are vulnerable to an Algorithmic Denial of Service DoS. By providing a specially crafted expression, an attacker can trigger excessive resource consumption during evaluation, leading to application degradation or...

GHSA-WXPP-56Q6-5PCG Spring Framework Denial of Service via Unbounded Cache in SpEL

Applications which accept user-supplied Spring Expression Language SpEL expressions may be vulnerable to a Denial of Service DoS attack if the evaluation of a SpEL expression triggers unbounded cache growth. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0...

Spring Framework Arbitrary Method Invocation in SpEL Expressions

A vulnerability in Spring Expression Language SpEL evaluation logic allows for arbitrary zero-argument method invocation, even within restricted or read-only contexts, which may allow an attacker to invoke unintended application logic. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2....

GHSA-775G-4XR8-78H8 Spring Framework Denial of Service via Integer Overflow in SpEL Expressions

An integer overflow vulnerability exists in the evaluation logic of the Spring Expression Language SpEL. An attacker can exploit this by supplying a specially crafted SpEL expression that triggers excessive resource consumption, resulting in a Denial of Service DoS. Affected versions: Spring...

GHSA-659M-PX2C-25WJ Spring Framework Denial of Service via AntPathMatcher

Applications may be vulnerable to a Regular Expression Denial of Service ReDoS attack if an attacker is able to provide a pattern which is then directly or indirectly supplied to one of the following methods in AntPathMatcher: matchString pattern, String path, matchStartString pattern, String pat...

GHSA-CJPG-RGQ5-FR37 Spring Framework Multipart Request Smuggling in Spring MVC and WebFlux

Spring MVC and WebFlux applications are vulnerable to Multipart request smuggling attacks. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48...

GHSA-9F52-RJQV-25QV Spring Framework Arbitrary Method Invocation in SpEL Expressions

A vulnerability in Spring Expression Language SpEL evaluation logic allows for arbitrary zero-argument method invocation, even within restricted or read-only contexts, which may allow an attacker to invoke unintended application logic. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2....

GHSA-957G-F97V-VPPC Spring Framework Cross-site Scripting via JSP Form Tags

Spring MVC applications which accept user-supplied values in the cssClass, cssErrorClass, or cssStyle attributes of JSP form tags allow arbitrary HTML/JavaScript code injection, potentially resulting in a cross-site scripting XSS vulnerability. Affected versions: Spring Framework 7.0.0 through...

GHSA-H3QP-GQRC-Q736 Spring Framework Open Redirect in Spring MVC and WebFlux

A Spring MVC or Spring WebFlux application which configures a mapping for "/" where the view name is not explicitly specified allows an attacker to craft a link resulting in a 302 redirect to an arbitrary external host via the redirect: prefix. Affected versions: Spring Framework 7.0.0 through...

GHSA-X23C-287F-QQV5 Spring Framework Denial of Service via Versioned Resources in Spring MVC and WebFlux

Spring MVC and WebFlux applications are vulnerable to Denial of Service DoS attacks when resolving static resources. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48...

GHSA-2827-2MXX-J8PV Spring Retry has Cache Exhaustion in Stateful Retries that leads to Denial of Service

An attacker can craft a large number of unique requests that trigger a failure, exhausting the capacity of the application-wide stateful retry cache. Once the cache is full, it permanently rejects any further updates, causing all later stateful retries and circuit breakers in the application to...

GHSA-JRV5-8W28-4265 Spring LDAP has Authentication Bypass with Empty Password

Spring LDAP's DirContextAuthenticationStrategy implementations do not reject a bind request where a non-empty username is paired with an empty or null password. Affected versions: Spring LDAP 2.4.0 through 2.4.4; 3.2.0 through 3.2.17; 3.3.0 through 3.3.7; 4.0.0 through 4.0.3...

Spring Framework Escalation via Session Fixation in WebFlux

A WebFlux application with a compromised subdomain for example, compromised via cross-site scripting XSS is vulnerable to an escalation attack exchanging a known session ID for that of an authenticated user. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0...
