Description

This security bulletin contains information about 4 vulnerabilities.


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

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

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 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.


2) Always-Incorrect Control Flow Implementation (CVE-ID: CVE-2026-41988)

CWE-ID: CWE-670 - Always-Incorrect Control Flow Implementation

CVSSv4: 2 [CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N]


The vulnerability allows a local user to modify data on the system.

The vulnerability exists due to uuid can make unexpected writes when external output buffers are used. A local user can gain unauthorized access to modify data on the system.


3) Uncontrolled Recursion (CVE-ID: CVE-2026-9358)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/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 the toString function in src/selectors/container.js of the AST serialization component when serializing a manipulated AST. A remote attacker can execute a manipulation to cause a denial of service.

User interaction is required.


4) Prototype pollution (CVE-ID: CVE-2025-64718)

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

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


The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation. A remote attacker can pass specially crafted input to the application and perform prototype pollution attacks.
