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.

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 10 Nov 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.

AI-suggested

Upgrade Adminer to version 6.0.2 or later, where this SSRF vulnerability is fixed. If upgrading is not immediately possible, ensure that the optional Elasticsearch driver is not deployed or disable PHP's allow_url_fopen setting to prevent exploitation. Since the vulnerability requires explicit deployment of the Elasticsearch driver, avoiding its use mitigates the risk.

Description

Adminer versions from 0 up to but not including 6.0.2 contain a pre-authentication Server-Side Request Forgery (SSRF) vulnerability in the optional Elasticsearch driver. This flaw allows an unauthenticated attacker to cause the server to make HTTP GET requests to arbitrary internal or external hosts by submitting crafted authentication parameters. The vulnerability enables internal network reconnaissance and service fingerprinting via error messages displayed on the login page. Exploitation requires the Elasticsearch driver to be explicitly enabled and PHP's allow_url_fopen setting to be active. The issue is fixed in Adminer version 6.0.2.

Impact

An unauthenticated attacker can leverage this SSRF vulnerability to perform internal network reconnaissance and service fingerprinting by causing the Adminer server to send HTTP requests to arbitrary hosts and ports within the network. This can reveal information about internal services and network topology. However, exploitation requires the optional Elasticsearch driver to be enabled and PHP's allow_url_fopen setting to be active. The vulnerability has a CVSS 4.0 base score of 6.9 (medium severity). No known exploits in the wild have been reported.

Summary

CVE-2026-100696 is a pre-authentication SSRF vulnerability in Adminer's optional Elasticsearch driver (plugins/drivers/elastic.php) affecting versions >=0 <6.0.2. The vulnerability arises because Adminer calls Driver::connect() before validating login credentials, allowing crafted auth parameters to trigger HTTP GET requests to arbitrary hosts and ports. The driver does not block loopback, private, or reserved IP addresses and appends default port 9200 if none is specified. Ports below 1024 are rejected. Error responses from these requests are partially rendered on the login page, providing an oracle for port scanning and internal network reconnaissance. Exploitation requires the Elasticsearch driver to be explicitly deployed and PHP's allow_url_fopen enabled. The vulnerability is fixed in version 6.0.2.
