Server-Sent Events (SSE) stream corruption affects Spring MVC applications built on the functional web framework across Spring Framework 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19 and 7.0.0-7.0.8, where unneutralized CRLF sequences (CWE-93) let an attacker inject into or corrupt the event stream. Reported by VMware/Spring and tagged as Information Disclosure, the flaw can break stream framing and potentially leak or splice data across SSE responses. No public exploit identified at time of analysis, and EPSS is low (0.16%, 6th percentile), but the vendor-assigned CVSS of 9.8 (all-High impact) sits in tension with the information-disclosure framing and warrants scrutiny.
Safety-guard bypass in the Spring Framework SpEL engine (VMware/Broadcom) lets attacker-controlled expression input escape the restricted SimpleEvaluationContext sandbox when the SpEL bytecode compiler is active, affecting Spring Framework 5.2.x through 7.0.8 across the 5.3, 6.0, 6.1, 6.2 and 7.0 lines. Because SimpleEvaluationContext is the API applications are told to use to safely evaluate untrusted expressions, this bypass can escalate a data-binding-only context into broader method invocation with high integrity and availability impact (CVSS 9.1, CWE-913). There is no public exploit identified at time of analysis, and EPSS is low (0.16%, 5th percentile), indicating no observed mass exploitation yet.
Denial of Service exposure in Spring Framework's data binding infrastructure allows unauthenticated remote attackers to exhaust application resources by submitting crafted property path expressions to any endpoint that binds user-supplied paths onto Java target objects. Affected versions span the entire actively maintained Spring Framework lineage - 5.2.x through 7.0.x - making the aggregate exposure footprint very large. No public exploit is referenced and EPSS sits at 0.15% (4th percentile), indicating low current exploitation activity despite the high CVSS score of 7.5.
Spring WebFlux applications that enable WebSocket connections leak request headers - potentially containing Authorization tokens, session cookies, or API keys - through exception reason messages exposed over the WebSocket channel. All maintained Spring Framework release trains from 5.2.x through 7.0.x are affected, covering the vast majority of actively deployed Spring reactive applications. The vulnerability is classified as information disclosure (CWE-209), and while the CVSS score is 7.5, the EPSS score of 0.14% (4th percentile) indicates very low observed exploitation probability; no public exploit or CISA KEV listing exists at time of analysis.
Authorization bypass in Spring Framework WebFlux functional-endpoint applications deployed on DispatcherServlet allows an attacker to defeat header-based route predicates by sending a CORS pre-flight (OPTIONS) request, reaching routes that should have been gated by header conditions. It affects Spring Framework 5.2.5-5.2.25, 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19, and 7.0.0-7.0.8 in the specific WebFlux-functional-plus-DispatcherServlet deployment mode. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.19%, 9th percentile).
Denial of service in Spring Framework WebFlux applications (5.2.25.RELEASE and earlier, 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19, 7.0.0-7.0.8) occurs when the Aalto XML processor is used to parse request bodies, because the maxInMemorySize buffering limit is not correctly enforced. Remote attackers can submit oversized XML to trigger unbounded in-memory buffering and exhaust heap memory. No public exploit identified at time of analysis; EPSS is low (0.14%, 4th percentile) and CISA SSVC lists exploitation status as none, though it rates the flaw automatable with total technical impact.
Cross-response information disclosure and stream corruption affects Spring Framework 6.2.0-6.2.19 and 7.0.0-7.0.8 (both MVC and WebFlux) when applications serve Server-Sent Events (SSE) together with view fragments, letting remote attackers corrupt the event stream and potentially bleed data across responses. No public exploit is identified at time of analysis and CISA has not listed the flaw in KEV; EPSS is low at 0.15% (5th percentile). The vendor-assigned 9.8 rating sits uneasily against the CWE-93 root cause, the 'Information Disclosure' tagging, and the SSVC 'exploitation: none' status, suggesting the paper severity outruns observed real-world risk.
WebFlux applications in Spring Framework running on the Jetty 12 Core reactive adapter omit the SameSite cookie attribute from serialized response cookies, exposing session and authentication cookies to cross-site request contexts. Affected versions span Spring Framework 6.2.0-6.2.19 and 7.0.0-7.0.8, covering a substantial footprint of reactive Java deployments on Jetty 12. The vulnerability carries a vendor CVSS of 7.5 with C:H reflecting potential session-token disclosure; no public exploit code or active exploitation (CISA KEV) has been identified, and EPSS places exploitation probability at 0.14% (4th percentile).
Memory exhaustion in Spring Framework's RSocket server implementation allows unauthenticated remote attackers to crash or degrade affected applications by sending malformed SETUP frames that trigger unreclaimed heap allocations. All actively maintained Spring Framework branches are affected - 5.2.x through 7.0.x - with the condition that the application must explicitly expose an RSocket endpoint. No public exploit code has been identified at time of analysis, and CISA SSVC confirms no current exploitation activity, though the attack is classified as automatable.
Uncontrolled resource consumption in Spring Framework's SpEL evaluator allows unauthenticated remote attackers to trigger a Denial of Service by submitting expressions using the power operator (^) with BigDecimal or BigInteger operands and arbitrarily large exponents, causing unbounded CPU and memory exhaustion in the JVM. All maintained Spring Framework release lines from 5.2.x through 7.0.x are affected, covering a large portion of the enterprise Java ecosystem. No public exploit has been identified and exploitation probability is very low (EPSS 0.15%, 4th percentile), though SSVC flags the attack class as automatable.
Spring WebFlux's PartEventHttpMessageReader fails to enforce the configured maxPartSize limit when maxInMemorySize is explicitly set to -1, allowing remote unauthenticated attackers to upload multipart request parts of arbitrary size in violation of application-defined policy. Affected are Spring Framework 6.1.0 through 6.1.28, 6.2.0 through 6.2.19, and 7.0.0 through 7.0.8. No public exploit code has been identified at time of analysis and EPSS is very low at 0.15% (4th percentile), but the SSVC automatable flag means scanning and exploitation can be automated at scale against exposed endpoints.
Server-side request forgery and remote code execution affect the Spring Framework's XsltView component across the 5.2.x through 7.0.x branches (5.2.25.RELEASE and earlier, 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19, and 7.0.0-7.0.8). When a Spring MVC application maps '/**' to view rendering and does not explicitly set a view name, an attacker can steer view resolution to XsltView and supply a path that triggers outbound requests and code execution. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.16%), but SSVC rates the technical impact as total and automatable.
Unsafe JSON deserialization in Spring Framework's JMS message converters (MappingJackson2MessageConverter and JacksonJsonMessageConverter) lets an attacker who controls JMS message content instantiate arbitrary classes, enabling gadget-chain attacks that can escalate to unauthorized actions or remote code execution. It affects Spring Framework 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7 when applications consume messages from an untrusted JMS source. There is no public exploit identified at time of analysis, and despite a 9.8 CVSS the EPSS probability is only 0.04% and CISA SSVC rates exploitation as 'none'.
Denial of service in VMware's Spring Framework (versions 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7) lets remote attackers exhaust memory in applications that evaluate user-supplied Spring Expression Language (SpEL) expressions, where crafted expressions trigger unbounded internal cache growth. No authentication or user interaction is required per the CVSS vector (PR:N/UI:N), and the impact is availability-only (C:N/I:N/A:H). There is no public exploit identified at time of analysis, and the EPSS probability is very low (0.01%, 2nd percentile), though CISA's SSVC framework flags the issue as automatable.
Algorithmic denial of service in Spring Framework SpEL evaluation allows remote unauthenticated attackers to exhaust CPU/memory resources by submitting specially crafted Spring Expression Language expressions, degrading or crashing affected applications. Impacts Spring Framework 5.3.x through 7.0.x in any application that evaluates user-supplied SpEL. No public exploit identified at time of analysis, and the CVSS 7.5 score reflects high availability impact with no confidentiality or integrity compromise.
Denial of service in Spring Framework 5.3.0 through 5.3.48 allows remote unauthenticated attackers to exhaust server resources by submitting crafted Spring Expression Language (SpEL) expressions that trigger an integer overflow during evaluation. The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit identified at time of analysis. Applications that evaluate untrusted SpEL input are at greatest risk.
Denial of service in Spring Framework's AntPathMatcher allows remote unauthenticated attackers to exhaust CPU resources via Regular Expression Denial of Service (ReDoS) when attacker-controlled patterns are passed to match(), matchStart(), or extractUriTemplateVariables(). Affects Spring Framework 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7. No public exploit identified at time of analysis, EPSS is very low (0.01%, 2nd percentile), and SSVC indicates no observed exploitation.
Denial of service in Spring Framework's Spring MVC and WebFlux static resource resolution allows remote unauthenticated attackers to exhaust application resources, affecting versions 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7. The CVSS 7.5 score reflects high-impact availability damage over the network with no privileges or user interaction, and at time of analysis no public exploit identified at time of analysis. The flaw was reported by VMware (Spring's maintainer) and is tracked under the official Spring Security advisory.
Predictable WebSocket session IDs in Spring Framework's spring-websocket module allow remote attackers to guess or forge session identifiers and, when paired with weak authorization rules, hijack or interact with other users' WebSocket sessions. The flaw affects Spring Framework 5.3.x, 6.1.x, 6.2.x, and 7.0.x prior to patched releases; no public exploit identified at time of analysis and EPSS is very low (0.03%).
A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
HTTP response splitting in Spring Framework affects applications that construct Content-Disposition HTTP headers by concatenating untrusted user-supplied file names without stripping CRLF characters, allowing remote attackers to inject arbitrary headers into HTTP responses. The vulnerability spans the entire actively-maintained Spring Framework lineage - versions 5.2.x through 7.0.8 - giving it a broad potential surface across Java enterprise application portfolios. No public exploit is identified at time of analysis, and EPSS at 0.16% (6th percentile) indicates low current exploitation probability.
Reflected XSS in Spring Framework's MVC and WebFlux data-binding error rendering exposes users of vulnerable applications to arbitrary HTML and JavaScript injection. All active Spring Framework release trains are affected - versions 5.2.x through 7.0.8 - making the exposure surface extremely broad across enterprise Java deployments. An unauthenticated attacker (per CVSS PR:N) can craft a malicious URL containing injected script payloads that, when a victim clicks it, execute in the victim's browser context via reflected field-error output. No public exploit code has been identified and EPSS sits at 0.17% (7th percentile), indicating limited observed exploitation activity at time of analysis.
Path traversal in Spring Framework's FreeMarker integration allows authenticated remote attackers to read arbitrary files from the server's template path when a controller passes user-controlled input directly as a view name. Affected versions span every maintained Spring Framework branch from 5.2.x through 7.0.8, making the exposure broad in the Java ecosystem. No public exploit code or active exploitation has been identified; CISA's SSVC assessment rates technical impact as partial and the vulnerability as non-automatable, consistent with the configuration dependency required to trigger it.
Open redirect in Spring Framework's UrlFileNameViewController exposes users of affected Spring MVC applications to phishing and credential-harvesting attacks across all active Spring Framework release trains (5.2.x through 7.0.x). The flaw allows an unauthenticated attacker to craft a URL that causes the vulnerable application to redirect victims to an arbitrary external domain, exploiting the controller's path-to-view-name resolution when end-of-path mapping is used without a configured prefix. No active exploitation has been confirmed - EPSS sits at 0.14% (4th percentile) and CISA SSVC reports exploitation status as none, making this a targeted patching priority rather than an emergency.
Open redirect in Spring Framework's UrlHandlerFilter allows unauthenticated remote attackers to silently redirect authenticated users to attacker-controlled URLs. Affected are Spring Framework 7.0.0-7.0.8 and 6.2.0-6.2.19 in both Spring MVC and Spring WebFlux deployments where UrlHandlerFilter is configured with broadly matching URL patterns. No public exploit code exists and SSVC indicates no known active exploitation; however, the no-privilege, network-reachable attack vector makes this a credible phishing enabler in affected applications. EPSS sits at 0.15% (5th percentile), consistent with low-automated-exploitation likelihood.
Server-side request forgery (SSRF) in Spring Framework's UriComponentsBuilder affects applications that use this API to parse and validate externally supplied URL strings. Incorrect host parsing allows a remote, unauthenticated attacker - with user interaction - to cause the application server to issue requests to unintended internal or external destinations, exposing low-level confidentiality and integrity impacts. No public exploit identified at time of analysis and no CISA KEV listing; however, SSRF in widely deployed Java frameworks warrants attention in any internet-facing application that processes user-controlled URLs.
Multipart request smuggling in Spring Framework's MVC and WebFlux components exposes applications to HTTP request manipulation via CWE-444. Unauthenticated remote attackers (AV:N/AC:L/PR:N/UI:N per CVSS) can exploit inconsistent multipart boundary parsing to smuggle malformed HTTP requests, achieving low-integrity impact against affected deployments. No public exploit code and no CISA KEV listing have been identified at time of analysis; however, the zero-prerequisite attack profile and broad version coverage across four major Spring branches (5.3.x, 6.1.x, 6.2.x, 7.0.x) make this relevant to any Java shop running Spring MVC or WebFlux with multipart upload handling enabled.
Spring Expression Language (SpEL) evaluation logic in Spring Framework 5.3.x through 7.0.x fails to enforce method invocation restrictions in read-only or restricted contexts, allowing remote unauthenticated attackers (CVSS PR:N, AV:N) to invoke arbitrary zero-argument methods and trigger unintended application logic. Scored LOW (3.7) with only availability impact per CVSS (A:L), though the 'Authentication Bypass' tag and CWE-863 (Incorrect Authorization) suggest the authorization bypass itself may have broader implications not fully reflected in the score. No public exploit identified at time of analysis and no CISA KEV listing, but the wide version range across four active Spring Framework release trains represents significant ecosystem exposure.
Security bypass in Spring WebFlux's Kotlin Router DSL (CWE-284: Improper Access Control) allows remote unauthenticated attackers to circumvent access control rules in Spring Framework 5.3.0 through 5.3.48. The CVSS vector (AV:N/AC:H/PR:N/UI:N) indicates network-reachable exploitation without authentication, though high attack complexity constrains opportunistic exploitation. No public exploit identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Cross-site scripting (XSS) in Spring Framework's MVC JSP form tags allows unauthenticated remote attackers to inject arbitrary HTML or JavaScript into rendered pages by supplying malicious values through the cssClass, cssErrorClass, or cssStyle tag attributes. Applications across four active Spring Framework release lines (5.3.x through 7.0.x) are affected when they pass user-controlled input directly into these tag attributes. No public exploit code has been identified at time of analysis, and CISA has not listed this CVE in the Known Exploited Vulnerabilities catalog, but the broad installed base of Spring MVC in enterprise Java environments and the high confidentiality impact (session hijacking, credential theft) warrant prompt patching.
Cross-site scripting in Spring Framework versions 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7 allows remote attackers to inject JavaScript into victim browsers when applications rely on JavaScriptUtils.javaScriptEscape() for output encoding. The flaw stems from incomplete escaping in this utility method, and successful exploitation requires user interaction (UI:R) such as visiting a crafted page. No public exploit has been identified at time of analysis and the issue is not in CISA KEV.
Open redirect in Spring Framework (Spring MVC and Spring WebFlux) across four major version branches enables unauthenticated remote attackers to craft URLs that cause the application to issue a 302 HTTP redirect to an arbitrary attacker-controlled external host. The vulnerability is conditionally exploitable - requiring a catch-all wildcard route mapping without an explicit view name - and demands user interaction to trigger. CVSS rates this 4.2 Medium (AV:N/AC:H/PR:N/UI:R); no public exploit code or CISA KEV listing has been identified at time of analysis.
Path traversal in Spring Framework's static resource resolution exposes arbitrary server files to unauthenticated remote attackers across both Spring MVC and Spring WebFlux stacks. Four major release lines - 5.3.x, 6.1.x, 6.2.x, and 7.0.x - are affected, making this a broad-surface issue for the Java ecosystem. The CVSS vector confirms unauthenticated network access with high confidentiality impact, though the AC:H designation indicates non-trivial exploit conditions; no public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV.
Information disclosure in Spring Framework's static resource resolution affects Spring MVC and WebFlux applications across four active release lines (5.3.x, 6.1.x, 6.2.x, and 7.0.x). Unauthenticated remote attackers exploiting this flaw can access sensitive cached content served through the static resource handling pipeline, achieving high confidentiality impact. No public exploit code or CISA KEV listing has been identified at time of analysis, and the AC:H vector indicates exploitation requires specific conditions beyond default network access.
Denial of Service in Spring WebFlux's multipart request processing allows unauthenticated remote attackers to exhaust server resources across all supported Spring Framework branches. Affects Spring Framework 5.3.x through 7.0.x when applications use the reactive WebFlux stack and expose endpoints that accept multipart data. No public exploit code has been identified at time of analysis, and CISA KEV listing is absent, but the network-reachable, zero-privilege attack surface warrants prompt patching for internet-facing WebFlux deployments.
Session fixation in Spring Framework's WebFlux reactive stack (versions 5.3.x through 7.0.x) enables a remote attacker to hijack an authenticated user's session by leveraging a compromised subdomain - typically via cross-site scripting - to plant a known session ID and exchange it for the victim's authenticated session post-login. The attack is classified as CWE-384 and requires both a prior subdomain compromise and user interaction, placing real-world exploitability well below the headline concern for most deployments. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Denial of Service in Spring Framework's static resource serving affects Spring MVC and Spring WebFlux applications running on Windows, where crafted HTTP requests trigger abnormally slow Windows file system resolution, exhausting HTTP connection pools. Affected branches span 5.3.x through 7.0.x; fixed versions are available from VMware/Spring. No active exploitation is confirmed (not in CISA KEV), EPSS is 0.05% at the 16th percentile, and SSVC rates exploitation as 'none' - but the attack is automatable and unauthenticated, making it meaningful for any qualifying Windows Spring deployment.
Cache poisoning in Spring Framework's static resource handler allows network-accessible unauthenticated attackers to corrupt the resource cache with wrongly-encoded content, causing a denial of service for clients consuming the front-end. Affected are Spring MVC and Spring WebFlux applications across Spring Framework 5.3.x, 6.1.x, 6.2.x, and 7.0.x that explicitly configure the resource chain with both caching and encoded resource resolution enabled. No public exploit exists and no active exploitation has been identified; EPSS at 0.06% (17th percentile) and SSVC exploitation rating of 'none' confirm very low real-world risk at this time.
Disk exhaustion via undeleted temp files in Spring WebFlux multipart processing affects all actively maintained Spring Framework branches, allowing an authenticated remote attacker to consume available disk space on the host. Affected branches span 5.3.x, 6.1.x, 6.2.x, and 7.0.x, with fixed releases available for all. No public exploit exists and EPSS sits at the 9th percentile, but the network-accessible attack surface and potential for cascading host-level impact make this a meaningful availability risk for any Spring WebFlux deployment that handles multipart uploads.
Spring Framework applications using Java scripting engines (JRuby, Jython) for template views in Spring MVC or Spring WebFlux can leak sensitive file contents from outside intended directories through path traversal. Affected versions include 7.0.0-7.0.5, 6.2.0-6.2.16, 6.1.0-6.1.25, and 5.3.0-5.3.46, with no patch currently available. An unauthenticated remote attacker can read arbitrary files on the system with confidentiality impact.
CVE-2026-22735 is a security vulnerability (CVSS 2.6). Remediation should follow standard vulnerability management procedures.
Spring Framework versions 5.3.0 through 6.2.11 are vulnerable to a CSRF bypass in STOMP over WebSocket support, allowing an unauthenticated attacker to send unauthorized messages by tricking a victim into visiting a malicious page. This moderate-severity issue (CVSS 4.3) requires user interaction and only affects applications using Spring's STOMP/WebSocket messaging; confidentiality and availability are not impacted. No public exploit identified at time of analysis, and the EPSS score is low (0.31%, 22nd percentile).

Server-Sent Events (SSE) stream corruption affects Spring MVC applications built on the functional web framework across Spring Framework 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19 and 7.0.0-7.0.8, where unneutralized CRLF sequences (CWE-93) let an attacker inject into or corrupt the event stream. Reported by VMware/Spring and tagged as Information Disclosure, the flaw can break stream framing and potentially leak or splice data across SSE responses. No public exploit identified at time of analysis, and EPSS is low (0.16%, 6th percentile), but the vendor-assigned CVSS of 9.8 (all-High impact) sits in tension with the information-disclosure framing and warrants scrutiny.
Safety-guard bypass in the Spring Framework SpEL engine (VMware/Broadcom) lets attacker-controlled expression input escape the restricted SimpleEvaluationContext sandbox when the SpEL bytecode compiler is active, affecting Spring Framework 5.2.x through 7.0.8 across the 5.3, 6.0, 6.1, 6.2 and 7.0 lines. Because SimpleEvaluationContext is the API applications are told to use to safely evaluate untrusted expressions, this bypass can escalate a data-binding-only context into broader method invocation with high integrity and availability impact (CVSS 9.1, CWE-913). There is no public exploit identified at time of analysis, and EPSS is low (0.16%, 5th percentile), indicating no observed mass exploitation yet.
Denial of Service exposure in Spring Framework's data binding infrastructure allows unauthenticated remote attackers to exhaust application resources by submitting crafted property path expressions to any endpoint that binds user-supplied paths onto Java target objects. Affected versions span the entire actively maintained Spring Framework lineage - 5.2.x through 7.0.x - making the aggregate exposure footprint very large. No public exploit is referenced and EPSS sits at 0.15% (4th percentile), indicating low current exploitation activity despite the high CVSS score of 7.5.
Spring WebFlux applications that enable WebSocket connections leak request headers - potentially containing Authorization tokens, session cookies, or API keys - through exception reason messages exposed over the WebSocket channel. All maintained Spring Framework release trains from 5.2.x through 7.0.x are affected, covering the vast majority of actively deployed Spring reactive applications. The vulnerability is classified as information disclosure (CWE-209), and while the CVSS score is 7.5, the EPSS score of 0.14% (4th percentile) indicates very low observed exploitation probability; no public exploit or CISA KEV listing exists at time of analysis.
Authorization bypass in Spring Framework WebFlux functional-endpoint applications deployed on DispatcherServlet allows an attacker to defeat header-based route predicates by sending a CORS pre-flight (OPTIONS) request, reaching routes that should have been gated by header conditions. It affects Spring Framework 5.2.5-5.2.25, 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19, and 7.0.0-7.0.8 in the specific WebFlux-functional-plus-DispatcherServlet deployment mode. No public exploit identified at time of analysis, and EPSS exploitation probability is low (0.19%, 9th percentile).
Denial of service in Spring Framework WebFlux applications (5.2.25.RELEASE and earlier, 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19, 7.0.0-7.0.8) occurs when the Aalto XML processor is used to parse request bodies, because the maxInMemorySize buffering limit is not correctly enforced. Remote attackers can submit oversized XML to trigger unbounded in-memory buffering and exhaust heap memory. No public exploit identified at time of analysis; EPSS is low (0.14%, 4th percentile) and CISA SSVC lists exploitation status as none, though it rates the flaw automatable with total technical impact.
Cross-response information disclosure and stream corruption affects Spring Framework 6.2.0-6.2.19 and 7.0.0-7.0.8 (both MVC and WebFlux) when applications serve Server-Sent Events (SSE) together with view fragments, letting remote attackers corrupt the event stream and potentially bleed data across responses. No public exploit is identified at time of analysis and CISA has not listed the flaw in KEV; EPSS is low at 0.15% (5th percentile). The vendor-assigned 9.8 rating sits uneasily against the CWE-93 root cause, the 'Information Disclosure' tagging, and the SSVC 'exploitation: none' status, suggesting the paper severity outruns observed real-world risk.
WebFlux applications in Spring Framework running on the Jetty 12 Core reactive adapter omit the SameSite cookie attribute from serialized response cookies, exposing session and authentication cookies to cross-site request contexts. Affected versions span Spring Framework 6.2.0-6.2.19 and 7.0.0-7.0.8, covering a substantial footprint of reactive Java deployments on Jetty 12. The vulnerability carries a vendor CVSS of 7.5 with C:H reflecting potential session-token disclosure; no public exploit code or active exploitation (CISA KEV) has been identified, and EPSS places exploitation probability at 0.14% (4th percentile).
Memory exhaustion in Spring Framework's RSocket server implementation allows unauthenticated remote attackers to crash or degrade affected applications by sending malformed SETUP frames that trigger unreclaimed heap allocations. All actively maintained Spring Framework branches are affected - 5.2.x through 7.0.x - with the condition that the application must explicitly expose an RSocket endpoint. No public exploit code has been identified at time of analysis, and CISA SSVC confirms no current exploitation activity, though the attack is classified as automatable.
Uncontrolled resource consumption in Spring Framework's SpEL evaluator allows unauthenticated remote attackers to trigger a Denial of Service by submitting expressions using the power operator (^) with BigDecimal or BigInteger operands and arbitrarily large exponents, causing unbounded CPU and memory exhaustion in the JVM. All maintained Spring Framework release lines from 5.2.x through 7.0.x are affected, covering a large portion of the enterprise Java ecosystem. No public exploit has been identified and exploitation probability is very low (EPSS 0.15%, 4th percentile), though SSVC flags the attack class as automatable.
Spring WebFlux's PartEventHttpMessageReader fails to enforce the configured maxPartSize limit when maxInMemorySize is explicitly set to -1, allowing remote unauthenticated attackers to upload multipart request parts of arbitrary size in violation of application-defined policy. Affected are Spring Framework 6.1.0 through 6.1.28, 6.2.0 through 6.2.19, and 7.0.0 through 7.0.8. No public exploit code has been identified at time of analysis and EPSS is very low at 0.15% (4th percentile), but the SSVC automatable flag means scanning and exploitation can be automated at scale against exposed endpoints.
Server-side request forgery and remote code execution affect the Spring Framework's XsltView component across the 5.2.x through 7.0.x branches (5.2.25.RELEASE and earlier, 5.3.0-5.3.49, 6.0.0-6.0.30, 6.1.0-6.1.28, 6.2.0-6.2.19, and 7.0.0-7.0.8). When a Spring MVC application maps '/**' to view rendering and does not explicitly set a view name, an attacker can steer view resolution to XsltView and supply a path that triggers outbound requests and code execution. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.16%), but SSVC rates the technical impact as total and automatable.
Unsafe JSON deserialization in Spring Framework's JMS message converters (MappingJackson2MessageConverter and JacksonJsonMessageConverter) lets an attacker who controls JMS message content instantiate arbitrary classes, enabling gadget-chain attacks that can escalate to unauthorized actions or remote code execution. It affects Spring Framework 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7 when applications consume messages from an untrusted JMS source. There is no public exploit identified at time of analysis, and despite a 9.8 CVSS the EPSS probability is only 0.04% and CISA SSVC rates exploitation as 'none'.
Denial of service in VMware's Spring Framework (versions 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7) lets remote attackers exhaust memory in applications that evaluate user-supplied Spring Expression Language (SpEL) expressions, where crafted expressions trigger unbounded internal cache growth. No authentication or user interaction is required per the CVSS vector (PR:N/UI:N), and the impact is availability-only (C:N/I:N/A:H). There is no public exploit identified at time of analysis, and the EPSS probability is very low (0.01%, 2nd percentile), though CISA's SSVC framework flags the issue as automatable.
Algorithmic denial of service in Spring Framework SpEL evaluation allows remote unauthenticated attackers to exhaust CPU/memory resources by submitting specially crafted Spring Expression Language expressions, degrading or crashing affected applications. Impacts Spring Framework 5.3.x through 7.0.x in any application that evaluates user-supplied SpEL. No public exploit identified at time of analysis, and the CVSS 7.5 score reflects high availability impact with no confidentiality or integrity compromise.
Denial of service in Spring Framework 5.3.0 through 5.3.48 allows remote unauthenticated attackers to exhaust server resources by submitting crafted Spring Expression Language (SpEL) expressions that trigger an integer overflow during evaluation. The CVSS 7.5 score reflects high availability impact with no confidentiality or integrity loss, and no public exploit identified at time of analysis. Applications that evaluate untrusted SpEL input are at greatest risk.
Denial of service in Spring Framework's AntPathMatcher allows remote unauthenticated attackers to exhaust CPU resources via Regular Expression Denial of Service (ReDoS) when attacker-controlled patterns are passed to match(), matchStart(), or extractUriTemplateVariables(). Affects Spring Framework 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7. No public exploit identified at time of analysis, EPSS is very low (0.01%, 2nd percentile), and SSVC indicates no observed exploitation.
Denial of service in Spring Framework's Spring MVC and WebFlux static resource resolution allows remote unauthenticated attackers to exhaust application resources, affecting versions 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7. The CVSS 7.5 score reflects high-impact availability damage over the network with no privileges or user interaction, and at time of analysis no public exploit identified at time of analysis. The flaw was reported by VMware (Spring's maintainer) and is tracked under the official Spring Security advisory.
Predictable WebSocket session IDs in Spring Framework's spring-websocket module allow remote attackers to guess or forge session identifiers and, when paired with weak authorization rules, hijack or interact with other users' WebSocket sessions. The flaw affects Spring Framework 5.3.x, 6.1.x, 6.2.x, and 7.0.x prior to patched releases; no public exploit identified at time of analysis and EPSS is very low (0.03%).
A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
HTTP response splitting in Spring Framework affects applications that construct Content-Disposition HTTP headers by concatenating untrusted user-supplied file names without stripping CRLF characters, allowing remote attackers to inject arbitrary headers into HTTP responses. The vulnerability spans the entire actively-maintained Spring Framework lineage - versions 5.2.x through 7.0.8 - giving it a broad potential surface across Java enterprise application portfolios. No public exploit is identified at time of analysis, and EPSS at 0.16% (6th percentile) indicates low current exploitation probability.
Reflected XSS in Spring Framework's MVC and WebFlux data-binding error rendering exposes users of vulnerable applications to arbitrary HTML and JavaScript injection. All active Spring Framework release trains are affected - versions 5.2.x through 7.0.8 - making the exposure surface extremely broad across enterprise Java deployments. An unauthenticated attacker (per CVSS PR:N) can craft a malicious URL containing injected script payloads that, when a victim clicks it, execute in the victim's browser context via reflected field-error output. No public exploit code has been identified and EPSS sits at 0.17% (7th percentile), indicating limited observed exploitation activity at time of analysis.
Path traversal in Spring Framework's FreeMarker integration allows authenticated remote attackers to read arbitrary files from the server's template path when a controller passes user-controlled input directly as a view name. Affected versions span every maintained Spring Framework branch from 5.2.x through 7.0.8, making the exposure broad in the Java ecosystem. No public exploit code or active exploitation has been identified; CISA's SSVC assessment rates technical impact as partial and the vulnerability as non-automatable, consistent with the configuration dependency required to trigger it.
Open redirect in Spring Framework's UrlFileNameViewController exposes users of affected Spring MVC applications to phishing and credential-harvesting attacks across all active Spring Framework release trains (5.2.x through 7.0.x). The flaw allows an unauthenticated attacker to craft a URL that causes the vulnerable application to redirect victims to an arbitrary external domain, exploiting the controller's path-to-view-name resolution when end-of-path mapping is used without a configured prefix. No active exploitation has been confirmed - EPSS sits at 0.14% (4th percentile) and CISA SSVC reports exploitation status as none, making this a targeted patching priority rather than an emergency.
Open redirect in Spring Framework's UrlHandlerFilter allows unauthenticated remote attackers to silently redirect authenticated users to attacker-controlled URLs. Affected are Spring Framework 7.0.0-7.0.8 and 6.2.0-6.2.19 in both Spring MVC and Spring WebFlux deployments where UrlHandlerFilter is configured with broadly matching URL patterns. No public exploit code exists and SSVC indicates no known active exploitation; however, the no-privilege, network-reachable attack vector makes this a credible phishing enabler in affected applications. EPSS sits at 0.15% (5th percentile), consistent with low-automated-exploitation likelihood.
Server-side request forgery (SSRF) in Spring Framework's UriComponentsBuilder affects applications that use this API to parse and validate externally supplied URL strings. Incorrect host parsing allows a remote, unauthenticated attacker - with user interaction - to cause the application server to issue requests to unintended internal or external destinations, exposing low-level confidentiality and integrity impacts. No public exploit identified at time of analysis and no CISA KEV listing; however, SSRF in widely deployed Java frameworks warrants attention in any internet-facing application that processes user-controlled URLs.
Multipart request smuggling in Spring Framework's MVC and WebFlux components exposes applications to HTTP request manipulation via CWE-444. Unauthenticated remote attackers (AV:N/AC:L/PR:N/UI:N per CVSS) can exploit inconsistent multipart boundary parsing to smuggle malformed HTTP requests, achieving low-integrity impact against affected deployments. No public exploit code and no CISA KEV listing have been identified at time of analysis; however, the zero-prerequisite attack profile and broad version coverage across four major Spring branches (5.3.x, 6.1.x, 6.2.x, 7.0.x) make this relevant to any Java shop running Spring MVC or WebFlux with multipart upload handling enabled.
Spring Expression Language (SpEL) evaluation logic in Spring Framework 5.3.x through 7.0.x fails to enforce method invocation restrictions in read-only or restricted contexts, allowing remote unauthenticated attackers (CVSS PR:N, AV:N) to invoke arbitrary zero-argument methods and trigger unintended application logic. Scored LOW (3.7) with only availability impact per CVSS (A:L), though the 'Authentication Bypass' tag and CWE-863 (Incorrect Authorization) suggest the authorization bypass itself may have broader implications not fully reflected in the score. No public exploit identified at time of analysis and no CISA KEV listing, but the wide version range across four active Spring Framework release trains represents significant ecosystem exposure.
Security bypass in Spring WebFlux's Kotlin Router DSL (CWE-284: Improper Access Control) allows remote unauthenticated attackers to circumvent access control rules in Spring Framework 5.3.0 through 5.3.48. The CVSS vector (AV:N/AC:H/PR:N/UI:N) indicates network-reachable exploitation without authentication, though high attack complexity constrains opportunistic exploitation. No public exploit identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.
Cross-site scripting (XSS) in Spring Framework's MVC JSP form tags allows unauthenticated remote attackers to inject arbitrary HTML or JavaScript into rendered pages by supplying malicious values through the cssClass, cssErrorClass, or cssStyle tag attributes. Applications across four active Spring Framework release lines (5.3.x through 7.0.x) are affected when they pass user-controlled input directly into these tag attributes. No public exploit code has been identified at time of analysis, and CISA has not listed this CVE in the Known Exploited Vulnerabilities catalog, but the broad installed base of Spring MVC in enterprise Java environments and the high confidentiality impact (session hijacking, credential theft) warrant prompt patching.
Cross-site scripting in Spring Framework versions 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7 allows remote attackers to inject JavaScript into victim browsers when applications rely on JavaScriptUtils.javaScriptEscape() for output encoding. The flaw stems from incomplete escaping in this utility method, and successful exploitation requires user interaction (UI:R) such as visiting a crafted page. No public exploit has been identified at time of analysis and the issue is not in CISA KEV.
Open redirect in Spring Framework (Spring MVC and Spring WebFlux) across four major version branches enables unauthenticated remote attackers to craft URLs that cause the application to issue a 302 HTTP redirect to an arbitrary attacker-controlled external host. The vulnerability is conditionally exploitable - requiring a catch-all wildcard route mapping without an explicit view name - and demands user interaction to trigger. CVSS rates this 4.2 Medium (AV:N/AC:H/PR:N/UI:R); no public exploit code or CISA KEV listing has been identified at time of analysis.
Path traversal in Spring Framework's static resource resolution exposes arbitrary server files to unauthenticated remote attackers across both Spring MVC and Spring WebFlux stacks. Four major release lines - 5.3.x, 6.1.x, 6.2.x, and 7.0.x - are affected, making this a broad-surface issue for the Java ecosystem. The CVSS vector confirms unauthenticated network access with high confidentiality impact, though the AC:H designation indicates non-trivial exploit conditions; no public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV.
Information disclosure in Spring Framework's static resource resolution affects Spring MVC and WebFlux applications across four active release lines (5.3.x, 6.1.x, 6.2.x, and 7.0.x). Unauthenticated remote attackers exploiting this flaw can access sensitive cached content served through the static resource handling pipeline, achieving high confidentiality impact. No public exploit code or CISA KEV listing has been identified at time of analysis, and the AC:H vector indicates exploitation requires specific conditions beyond default network access.
Denial of Service in Spring WebFlux's multipart request processing allows unauthenticated remote attackers to exhaust server resources across all supported Spring Framework branches. Affects Spring Framework 5.3.x through 7.0.x when applications use the reactive WebFlux stack and expose endpoints that accept multipart data. No public exploit code has been identified at time of analysis, and CISA KEV listing is absent, but the network-reachable, zero-privilege attack surface warrants prompt patching for internet-facing WebFlux deployments.
Session fixation in Spring Framework's WebFlux reactive stack (versions 5.3.x through 7.0.x) enables a remote attacker to hijack an authenticated user's session by leveraging a compromised subdomain - typically via cross-site scripting - to plant a known session ID and exchange it for the victim's authenticated session post-login. The attack is classified as CWE-384 and requires both a prior subdomain compromise and user interaction, placing real-world exploitability well below the headline concern for most deployments. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Denial of Service in Spring Framework's static resource serving affects Spring MVC and Spring WebFlux applications running on Windows, where crafted HTTP requests trigger abnormally slow Windows file system resolution, exhausting HTTP connection pools. Affected branches span 5.3.x through 7.0.x; fixed versions are available from VMware/Spring. No active exploitation is confirmed (not in CISA KEV), EPSS is 0.05% at the 16th percentile, and SSVC rates exploitation as 'none' - but the attack is automatable and unauthenticated, making it meaningful for any qualifying Windows Spring deployment.
Cache poisoning in Spring Framework's static resource handler allows network-accessible unauthenticated attackers to corrupt the resource cache with wrongly-encoded content, causing a denial of service for clients consuming the front-end. Affected are Spring MVC and Spring WebFlux applications across Spring Framework 5.3.x, 6.1.x, 6.2.x, and 7.0.x that explicitly configure the resource chain with both caching and encoded resource resolution enabled. No public exploit exists and no active exploitation has been identified; EPSS at 0.06% (17th percentile) and SSVC exploitation rating of 'none' confirm very low real-world risk at this time.
Disk exhaustion via undeleted temp files in Spring WebFlux multipart processing affects all actively maintained Spring Framework branches, allowing an authenticated remote attacker to consume available disk space on the host. Affected branches span 5.3.x, 6.1.x, 6.2.x, and 7.0.x, with fixed releases available for all. No public exploit exists and EPSS sits at the 9th percentile, but the network-accessible attack surface and potential for cascading host-level impact make this a meaningful availability risk for any Spring WebFlux deployment that handles multipart uploads.
Spring Framework applications using Java scripting engines (JRuby, Jython) for template views in Spring MVC or Spring WebFlux can leak sensitive file contents from outside intended directories through path traversal. Affected versions include 7.0.0-7.0.5, 6.2.0-6.2.16, 6.1.0-6.1.25, and 5.3.0-5.3.46, with no patch currently available. An unauthenticated remote attacker can read arbitrary files on the system with confidentiality impact.
CVE-2026-22735 is a security vulnerability (CVSS 2.6). Remediation should follow standard vulnerability management procedures.
Spring Framework versions 5.3.0 through 6.2.11 are vulnerable to a CSRF bypass in STOMP over WebSocket support, allowing an unauthenticated attacker to send unauthorized messages by tricking a victim into visiting a malicious page. This moderate-severity issue (CVSS 4.3) requires user interaction and only affects applications using Spring's STOMP/WebSocket messaging; confidentiality and availability are not impacted. No public exploit identified at time of analysis, and the EPSS score is low (0.31%, 22nd percentile).
