Description
This security bulletin contains information about 6 vulnerabilities.
1) Inefficient Algorithmic Complexity (CVE-ID: CVE-2026-13149)
CWE-ID: CWE-407 - Inefficient Algorithmic Complexity
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 inefficient algorithmic complexity in expand() when processing attacker-influenced brace expansion patterns containing consecutive non-expanding {} groups. A remote attacker can send a specially crafted input string to cause a denial of service.
The issue can block the calling thread for minutes or indefinitely with a small all-ASCII input, and applications using Node's single-threaded event loop may fully stall a worker or process.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-14257)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
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 expand() when processing attacker-influenced brace expansion patterns. A remote attacker can send a specially crafted input string to cause a denial of service.
The issue can terminate the Node process with an uncatchable out-of-memory error.
3) Input validation error (CVE-ID: CVE-2026-49458)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary script in the victim's browser.
The vulnerability exists due to improper input validation in the IN_PLACE sanitization logic when processing markup across realms. A remote attacker can supply specially crafted markup that bypasses realm-bound instanceof checks to execute arbitrary script in the victim's browser.
User interaction is required to process the crafted content.
4) Cross-site scripting (CVE-ID: CVE-2026-49459)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The vulnerability allows a remote attacker to execute arbitrary script code in the victim's browser.
The vulnerability exists due to improper neutralization of script-related html attributes in the in_place mode root element handling when sanitizing attacker-controlled root dom content. A remote attacker can supply a crafted root element whose clobbered attributes are preserved to execute arbitrary script code in the victim's browser.
User interaction is required to load or process the crafted content.
5) Cross-site scripting (CVE-ID: CVE-2026-49978)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The vulnerability allows a remote attacker to execute arbitrary script in the victim's browser.
The vulnerability exists due to cross-site scripting in template content sanitization when processing HTML containing a template element with an attached shadow root inside template.content. A remote attacker can supply crafted HTML that survives sanitization to execute arbitrary script in the victim's browser.
Exploitation occurs when the application clones the template and inserts the result into the page.
6) Incorrect Control Flow Scoping (CVE-ID: CVE-2026-3449)
CWE-ID: CWE-705 - Incorrect Control Flow Scoping
CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to Incorrect Control Flow Scoping in promise resolving when AbortSignal option is used. The Promise remains in a permanently pending state after the signal is aborted, causing any await or .then() usage to hang indefinitely. A local user can trigger the vulnerability to cause a control-flow leak that can lead to stalled requests, blocked workers, or degraded application availability.
