The vulnerability allows a remote attacker to bypass host-based policy checks and route requests to an unintended destination.

The vulnerability exists due to interpretation conflict in the fast-uri URL parser when parsing URLs containing a literal backslash in the authority section for special schemes. A remote attacker can supply a specially crafted URL to bypass host-based policy checks and route requests to an unintended destination.

This issue can occur when an application validates a URL with fast-uri and then passes the same input to Node's WHATWG URL parser or fetch-related consumers, which extract a different host from the same string.


18) Interpretation Conflict (CVE-ID: CVE-2026-13676)

CWE-ID: CWE-436 - Interpretation Conflict

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to modify data on the system.

The vulnerability exists due to fast-uri fail to canonicalize Unicode (IDN) hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize() and equal() still return values that differ from a WHATWG-compatible URL parser. A remote attacker can trigger the vulnerability to modify data on the system.

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in static resource resolution in Spring MVC and Spring WebFlux when resolving versioned resources served from the file system. A remote attacker can send malicious requests that are slow to resolve to cause a denial of service.

Only applications that serve static resources from the file system and have versioned resources support configured are vulnerable.


20) Resource exhaustion (CVE-ID: CVE-2026-41851)

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the SpEL expression cache when evaluating user-supplied SpEL expressions. A remote attacker can submit crafted expressions to cause a denial of service.

Exploitation requires that the application accept and evaluate untrusted SpEL expressions and cache parsed SpEL expressions. A high volume of processing is typically required, often involving millions of evaluations, including with a single expression using dynamic inputs.


21) Out-of-bounds write (CVE-ID: CVE-2026-41907)

CWE-ID: CWE-787 - Out-of-bounds write

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to accepting external output buffers, but not rejecting out-of-range writes (small buf or large offset). A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.


22) CRLF injection (CVE-ID: CVE-2026-12143)

CWE-ID: CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]

The vulnerability exists due to insufficient validation of attacker-supplied data. A remote attacker can pass specially crafted data to the application containing CR-LF characters and modify application behavior.


23) Input validation error (CVE-ID: CVE-2026-40983)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in ObservationGrpcServerInterceptor when handling specially crafted gRPC requests. A remote attacker can send a specially crafted gRPC request to cause a denial of service.

The issue is exposed only when observations are recorded and metrics are output through DefaultMeterObservationHandler or a similarly behaving custom ObservationHandler.


24) Interpretation Conflict (CVE-ID: CVE-2026-18446)

CWE-ID: CWE-436 - Interpretation Conflict

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass host-based policy checks and steer requests to an unintended destination.

The vulnerability exists due to interpretation conflict in the fast-uri URI parser when parsing references that use backslash-based authority introducers. A remote attacker can supply a specially crafted URL to bypass host-based policy checks and steer requests to an unintended destination.

The issue arises from inconsistent host extraction between fast-uri and Node's WHATWG URL handling for special schemes.


25) Memory leak (CVE-ID: CVE-2026-56819)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in Http2Decompressor.decompress(...) in DelegatingDecompressorFrameListener when processing HTTP/2 DATA frames for a stream whose decompressor channel has already been closed. A remote attacker can send specially crafted HTTP/2 DATA frames to cause a denial of service.

Only applications that enable HTTP/2 content decompression via DelegatingDecompressorFrameListener are vulnerable.


26) Prototype pollution (CVE-ID: CVE-2026-67320)

CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')

CVSSv4: 6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to improperly controlled modification of object prototype attributes in the Node.js HTTP adapter request path when processing interceptor-returned regular object configs with a polluted Object.prototype.proxy. A remote user can trigger prototype pollution elsewhere in the process and cause affected HTTP requests to be routed through an attacker-controlled proxy to disclose sensitive information.

Exploitation requires Node.js HTTP adapter usage and a request interceptor that returns a plain object copy of the request configuration. The confirmed disclosure impact is limited to plaintext HTTP requests and can expose authorization headers, request metadata, and request body content.


27) SQL injection (CVE-ID: CVE-2026-0603)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose sensitive information and manipulate or delete data.

The vulnerability exists due to sql injection in InlineIdsOrClauseBuilder when processing ID values containing unsanitized non-alphanumeric characters. A remote user can supply crafted input to disclose sensitive information and manipulate or delete data.

This is only exploitable if the user is able to set their own IDs, those IDs allow non-alphanumeric characters, and the application is using InlineIdsOrClauseBuilder.
