44/100 CVSS 7.5 🔴 CVE ANALYSISPublished: July 1, 2026

SurrealDB has Denial of Service in JSON parser due to nested objects

The SurrealDB value and JSON parser did not enforce the configured recursion depth limit when parsing nested `{`, `[`, or `(` tokens. The expression parser already enforced the limit for these tokens; the value/JSON parser omitted it. An unauthenticated attacker could send a deeply nested JSON payload to the WebSocket `/rpc` endpoint and exhaust se...

⚠️ Business Impact Analysis

⚠️ Remote code execution — full server takeover without authentication possible
⚠️ Privilege escalation — local attacker can become SYSTEM/root
⚠️ Authentication bypass — all access controls circumvented

🔗 Attack Chain Analysis

Step-by-step attack chain based on observed TTPs and vulnerability characteristics:

#	Phase	Attacker Action	MITRE
1	Reconnaissance	Attacker identifies exposed surrealdb instances via Shodan, Censys, or targeted scanning	`TA0043`
2	Initial Access	Unauthenticated exploitation — no credentials required. Single HTTP request sufficient	`T1190`
3	Execution	Remote code execution achieved — attacker runs arbitrary commands on target system	`T1203`
4	Privilege Escalation	Local privilege escalation to SYSTEM/root for full control	`T1068`
5	Persistence	Backdoor, scheduled task, or new admin account created for persistent access	`T1053`
6	Command & Control	Attacker establishes persistent C2 channel using HTTPS or DNS tunneling	`T1071`
7	Impact / Objectives	Intellectual property theft, espionage, cryptomining, or preparation for future attack stage	`T1657`

⚠ Deep Dive Analysis

This high-severity vulnerability in rust surrealdb (CVSS 7.5) represents a significant attack surface. SENTINEL APEX assesses exploitation to be technically feasible with moderate effort. Organizations running surrealdb in internet-facing or privileged positions face immediate risk.

SENTINEL APEX URGENCY: ELEVATED. Score: 44/100 LOW. Patch before exploitation activity begins.
