Description
This security bulletin contains information about 2 vulnerabilities.
1) Interpretation Conflict (CVE-ID: CVE-2026-13676)
CWE-ID: CWE-436 - Interpretation Conflict
CVSSv4: 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/E:U/U:Amber
The vulnerability allows a remote attacker to modify data on the system.
The vulnerability exists due to fast-uri fail to canonicalize Unicode (IDN) hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize() and equal() still return values that differ from a WHATWG-compatible URL parser. A remote attacker can trigger the vulnerability to modify data on the system.
2) Command Injection (CVE-ID: CVE-2026-9277)
CWE-ID: CWE-77 - Command injection
CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/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 commands on the system.
The vulnerability exists due to shell-quote's `quote()` function did not validate object-token inputs against the operator model used by `parse()`.. A remote attacker can pass specially crafted data to the application and execute arbitrary commands.
