Description
This security bulletin contains information about 5 vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-35469)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Code Injection (CVE-ID: CVE-2026-44293)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to improper control of code generation in generated toObject code when processing an attacker-controlled protobuf descriptor with a non-string default value for a bytes field and converting a message with defaults enabled. A remote user can provide a crafted descriptor to execute arbitrary code.
Exploitation requires the application to load an attacker-controlled schema or descriptor and call toObject with defaults enabled for the affected type.
3) Code Injection (CVE-ID: CVE-2026-4800)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: 9.2 [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]
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to improper control of code generation in _.template when processing untrusted options.imports key names. A remote attacker can supply crafted imports key names to execute arbitrary code.
Code execution occurs at template compilation time. If Object.prototype has been polluted by another vector, inherited polluted keys can also be copied into the imports object and passed to Function().
4) Interpretation Conflict (CVE-ID: CVE-2026-6322)
CWE-ID: CWE-436 - Interpretation Conflict
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 bypass host-based security checks and route requests to an unintended authority.
The vulnerability exists due to interpretation conflict in the URI host component when processing percent-encoded authority delimiters. A remote attacker can supply a specially crafted URL to bypass host-based security checks and route requests to an unintended authority.
This issue can affect applications that normalize untrusted URLs before host allowlist checks, redirect validation, or outbound request routing.
5) Command Injection (CVE-ID: CVE-2026-9277)
CWE-ID: CWE-77 - Command injection
CVSSv4: 9.2 [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]
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.
