Integrity: Low
Availability: None

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

AI-suggested

Until an official fix is released, users should exercise caution when opening CSV files exported from this plugin, especially if received from untrusted sources. Applying input sanitization or filtering on exported CSV content manually may reduce risk. Monitor the vendor's channels for updates or patches addressing this vulnerability.

Description

The AI Chatbot Free Models – Customer Support, Live Chat, Virtual Assistant plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 1.6.5. This is due to insufficient sanitization in the 'newcodebyte_chatbot_export_messages' function. This makes it possible for unauthenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Impact

An attacker can inject malicious formula code into CSV files exported by the plugin, which may execute when the file is opened by a user in a vulnerable spreadsheet application. This can lead to limited integrity impact such as executing unintended commands or scripts on the local system. There is no direct impact on confidentiality or availability according to the CVSS vector. The vulnerability requires user interaction (opening the CSV file) and does not require authentication to exploit.

Summary

The AI Chatbot Free Models plugin for WordPress suffers from a CSV Injection vulnerability (CWE-1236) due to improper neutralization of formula elements in CSV exports generated by the 'newcodebyte_chatbot_export_messages' function. This allows unauthenticated attackers to embed malicious input into CSV files, which may execute code when opened in spreadsheet software that processes formulas. The vulnerability affects all versions up to and including 1.6.5. The CVSS 3.1 base score is 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N), reflecting network attack vector, low complexity, no privileges required, user interaction needed, unchanged scope, no confidentiality or availability impact, and limited integrity impact.

CWE-1236Improper Neutralization of Formula Elements in a CSV File (opens in a new tab)
Base weakness
The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.
Implementation
When generating CSV output, ensure that formula-sensitive metacharacters are effectively escaped or removed from all data before storage in the resultant CSV. Risky characters include '=' (equal), '+' (plus), '-' (minus), and '@' (at).
Implementation
If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.
Architecture and Design
Certain implementations of spreadsheet software might disallow formulas from executing if the file is untrusted, or if the file is not authored by the current user.
