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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Subsequent System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 30 Oct 2026
Detectable: no evidence on record.
No public nuclei template indexed

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

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

What to do

Upgrade goniszewski grimoire to 1.0.0.

Affected software

AI-suggested

Upgrade Grimoire to version 1.0.0 or later, where this SSRF vulnerability is fixed. No other mitigation is required as the fix addresses the root cause by enforcing proper authentication checks before processing user-supplied URLs.

Description

Grimoire versions before 1.0.0 have an unauthenticated server-side request forgery (SSRF) vulnerability in the /api/fetch-metadata POST endpoint. This flaw allows attackers to submit arbitrary URLs, including those targeting internal or cloud metadata services, and retrieve parsed metadata such as title, description, and page content without authentication.

Impact

An unauthenticated attacker can exploit this SSRF vulnerability to make the server perform HTTP requests to internal or cloud metadata endpoints. This may lead to unauthorized disclosure of sensitive metadata information such as titles, descriptions, and page content from internal resources. Although no known exploits are reported in the wild, the vulnerability could facilitate reconnaissance or further attacks against internal network services.

Summary

CVE-2026-119709 describes an SSRF vulnerability in goniszewski's Grimoire software prior to version 1.0.0. The vulnerability exists in the /api/fetch-metadata POST handler, which calls getMetadata() on user-supplied URLs without performing authentication checks. This enables unauthenticated attackers to induce the server to make HTTP requests to internal or cloud metadata endpoints and obtain sensitive metadata information. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The issue is fixed in Grimoire version 1.0.0.
