Description

This security bulletin contains information about 2 vulnerabilities.


1) Uncontrolled recursion (CVE-ID: CVE-2025-59789)

CWE-ID: CWE-674 - Uncontrolled Recursion

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 perform a denial of service (DoS) attack.

The vulnerability exists due to uncontrolled recursion in the json2pb component. A remote attacker can send specially crafted JSON data and perform a denial of service (DoS) attack.

CWE-ID: CWE-88 - Argument Injection or Modification

CVSSv4: 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/E:P/U:Green


The vulnerability allows a remote user to execute arbitrary OS commands on the system.

The vulnerability exists due to improper input validation within the bRPC heap profiler built-in service (/pprof/heap). A remote user can pass specially crafted input via the extra_options parameter and executes it as a command-line argument.
