Description
This security bulletin contains information about 3 vulnerabilities.
1) Improper Handling of Unexpected Data Type (CVE-ID: CVE-2025-7339)
CWE-ID: CWE-241 - Improper Handling of Unexpected Data Type
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker can inadvertently modify response headers when an array is passed to `response.writeHead()`
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-22036)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to allocation of resources without limits or throttling in the fetch() API and undici decompress interceptor when processing HTTP responses with chained Content-Encoding values. A remote attacker can send a specially crafted response with thousands of compression steps to cause a denial of service.
3) Improper Authorization (CVE-ID: CVE-2026-33186)
CWE-ID: CWE-285 - Improper Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to gain access to bypass authorization.
The vulnerability exists due to authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. A remote attacker can send raw HTTP/2 frames with malformed `:path` headers directly to the gRPC server to bypass authorization.
