Description
This security bulletin contains information about 5 vulnerabilities.
1) Path traversal (CVE-ID: CVE-2026-23745)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
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.
2) Race condition (CVE-ID: CVE-2026-23950)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N/E:P/U:Green
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.
3) Path traversal (CVE-ID: CVE-2026-24842)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green
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) Prototype pollution (CVE-ID: CVE-2025-13465)
CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
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.
5) Resource exhaustion (CVE-ID: CVE-2025-15284)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 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/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the arrayLimit option does not enforce limits for bracket notation (a[]=1&a[]=2). A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
