Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Jul 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

## Summary The `/api/settings/database` endpoint allows full database export (containing all credentials, API keys, OAuth tokens, and settings) and full database import (complete overwrite) without any authentication requirement beyond the `ALWAYS_PROTECTED` middleware check, which only validates JWT or CLI token. Combined with other vulnerabilities (e.g., default password, tunnel exposure), this enables complete database takeover. ## Description The endpoint `/api/settings/database` is listed in `ALWAYS_PROTECTED` in `dashboardGuard.js` (line 42), which requires a valid JWT token or CLI token. However, this protection is insufficient because: 1. **GET (Export):** Returns the complete database including API keys (`key` field in `apiKeys` table), OAuth tokens, and all provider credentials. Line 80 in `src/lib/db/index.js`: `apiKeys: db.all("SELECT * FROM apiKeys").map(...)` — the `key` field contains the plaintext API key value. 2. **POST (Import):** Accepts arbitrary JSON and performs a complete database wipe-and-replace in a transaction (lines 102-163 in `src/lib/db/index.js`). This replaces all settings including the password hash, effectively allowing an attacker to set their own password. 3. The exported data includes `apiKeys` with their plaintext `key` values, `providerConnections` with all OAuth tokens, and `settings` with OIDC client secrets. ### Evidence **File:** `src/app/api/settings/database/route.js` ```javascript export async function GET() { const payload = await exportDb(); return NextResponse.json(payload); } export async function POST(request) { const payload = await request.json(); await importDb(payload); // ... } ``` **File:** `src/lib/db/index.js` (lines 96-163) ```javascript export async function importDb(payload) { db.transaction(() => { // Wipe all tables db.run(`DELETE FROM settings`); db.run(`DELETE FROM providerConnections`); db.run(`DELETE FROM providerNodes`); db.run(`DELETE FROM proxyPools`); db.run(`DELETE FROM apiKeys`); db.run(`DELETE FROM combos`); db.run(`DELETE FROM kv WHERE scope IN (...)`); // Then insert attacker-controlled data // ... }); } ``` The `exportDb` function at line 80 exposes API key plaintext: ```javascript apiKeys: db.all(`SELECT * FROM apiKeys`).map((r) => ({ id: r.id, key: r.key, name: r.name, ... })), ``` ## Steps to Reproduce 1. Authenticate with any valid JWT (e.g., using the default password "123456") 2. Export: `curl -b auth_token=<jwt> http://localhost:20128/api/settings/database` 3. Observe: Full database dump with all credentials in plaintext 4. Import malicious data: `curl -X POST -b auth_token=<jwt> -H "Content-Type: application/json" -d '<modified-db>' http://localhost:20128/api/settings/database` 5. All settings, passwords, API keys are now replaced with attacker-controlled values ## Impact - **Confidentiality:** Complete exposure of all stored secrets (API keys, OAuth tokens, OIDC client secrets) - **Integrity:** Complete database replacement with attacker-controlled data - **Availability:** Database wipe is possible by importing an empty database - **Scope Changed:** Importing new settings affects all users and downstream services ## Recommended Fix 1. Require re-authentication for database export/import (not just an existing session) 2. Mask/redact API keys in export (or require explicit opt-in for key export) 3. Add confirmation step for import (require current password verification) 4. Implement database backup before import 5. Log all export/import operations with audit trail

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
