Description
This security bulletin contains information about 5 vulnerabilities.
1) Cross-site scripting (CVE-ID: CVE-2026-33244)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear
The vulnerability allows a remote user to execute arbitrary script in the victim's browser.
The vulnerability exists due to cross-site scripting in prerendered redirect HTML generation when processing an untrusted HTTP Location header value. A remote user can supply a crafted redirect location to execute arbitrary script in the victim's browser.
Only applications using Framework Mode with pre-rendering enabled are vulnerable. User interaction is required to load the generated HTML file.
2) Resource exhaustion (CVE-ID: CVE-2026-34077)
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 cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in the single-fetch serialization algorithm when encoding specific types of data into server responses. A remote attacker can supply crafted input that is reflected into a server response to cause a denial of service.
Only React Router v7 framework mode and Remix with single fetch enabled are vulnerable.
3) Input validation error (CVE-ID: CVE-2026-40181)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to redirect users to an external domain.
The vulnerability exists due to improper input validation in the redirect function when processing URLs with a path starting with // that is reinterpreted as a protocol-relative URL. A remote attacker can supply a crafted URL to redirect users to an external domain.
This does not affect applications using declarative mode.
4) Deserialization of Untrusted Data (CVE-ID: CVE-2026-42211)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to deserialization of untrusted data in React Router framework mode when handling external requests in an application that also contains an existing prototype pollution vulnerability. A remote attacker can send crafted external requests to execute arbitrary code.
Exploitation requires chaining with a pre-existing prototype pollution vulnerability in the application code and affects framework mode only.
5) Resource exhaustion (CVE-ID: CVE-2026-42342)
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 cause a denial of service.
The vulnerability exists due to uncontrolled resource consumption in the __manifest endpoint when handling crafted requests with unbounded path expansion. A remote attacker can send a specially crafted request to cause a denial of service.
Only React Router Framework Mode applications are affected; Declarative Mode and Data Mode are not impacted.
