81) Infinite loop (CVE-ID: CVE-2026-67214)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:H/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 perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the customAlphabet and nanoid functions of its non-secure module (nanoid/non-secure). A remote attacker can consume all available system resources and cause denial of service conditions.

82) Resource exhaustion (CVE-ID: CVE-2026-69152)

CWE-ID: CWE-400 - Resource exhaustion

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 the expand() function when processing attacker-controlled brace patterns. A remote attacker can send a specially crafted input to cause a denial of service.

The issue can terminate the Node process with an uncatchable out-of-memory error or block the event loop for an extended period.

83) Path traversal (CVE-ID: CVE-2026-69153)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.

84) Uncontrolled Recursion (CVE-ID: CVE-2026-67313)

CWE-ID: CWE-674 - Uncontrolled Recursion

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 recursion in formDataToJSON when processing attacker-controlled FormData field names during FormData-to-JSON conversion. A remote attacker can supply a crafted FormData field name with deeply nested bracket segments to cause a denial of service.

The vulnerable request-transform path is reached when FormData is sent with an application/json content type, and direct use of formToJSON() throws synchronously.
