Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Improper verification of cryptographic signature (CVE-ID: CVE-2025-65945)
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to improper signature verification under specific conditions when using the HS256 algorithm within the jws.createVerify() function. A remote attacker can manipulate header or payload in the HMAC secret lookup routines and bypass authorization checks.
2) Path traversal (CVE-ID: CVE-2026-23745)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in src/unpack.ts within the [HARDLINK] and [SYMLINK] methods. A remote attacker can send a specially crafted HTTP request and read/overwrite arbitrary files on the system.
3) Path traversal (CVE-ID: CVE-2026-24842)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in lib/unpack.js. A remote attacker can send a specially crafted HTTP request and read or overwrite arbitrary files on the system.
4) XML External Entity injection (CVE-ID: CVE-2019-10172)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
5) XML External Entity injection (CVE-ID: CVE-2016-3720)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input within the XmlMapper. A remote attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
6) Prototype pollution (CVE-ID: CVE-2025-13465)
The vulnerability allows a remote attacker to alter application's behavior.
The vulnerability exists due to improper input validation within the in the _.unset and _.omit functions. A remote attacker can pass specially crafted input to the application and delete methods from global prototypes.
7) Race condition (CVE-ID: CVE-2026-23950)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a race condition in Path Reservations via Unicode Sharp-S (ß) Collisions on macOS APFS. A remote attacker can trick the victim into using a specially crafted archive to bypass the library's internal concurrency safeguards and perform Symlink Poisoning attacks.
