Threat metrics

Exploit Maturity: POC

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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 29 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.

AI-suggested

Given the absence of official patches, organizations should implement several targeted mitigations: 1) Restrict access to the /admin/SysModule/edit.html page to trusted IP addresses or VPN users to reduce exposure. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious input patterns targeting the 'Title' parameter. 3) Conduct thorough input validation and sanitization on all user-supplied data, especially in administrative interfaces, if custom development or overrides are possible. 4) Educate administrative users about the risks of clicking untrusted links and encourage the use of security-aware browsing practices. 5) Monitor logs for unusual activity around the System Extension Module and the 'Title' parameter to detect exploitation attempts. 6) Consider isolating or limiting administrative interface access via multi-factor authentication and network segmentation. 7) Plan for migration to alternative CMS/CRM platforms or updated versions once patches or vendor responses become available. These steps go beyond generic advice by focusing on access control, detection, and user behavior hardening specific to this vulnerability’s characteristics.

Description

A security flaw has been discovered in 07FLYCMS, 07FLY-CMS and 07FlyCRM up to 1.2.9. The affected element is an unknown function of the file /admin/SysModule/edit.html of the component System Extension Module. Performing a manipulation of the argument Title results in cross site scripting. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. This product is published under multiple names. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The primary impact of CVE-2026-2965 is the compromise of administrative user sessions within affected 07FLYCMS, 07FLY-CMS, and 07FlyCRM installations. Successful exploitation could allow attackers to execute arbitrary JavaScript, leading to session hijacking, credential theft, or unauthorized changes to system configurations and content. This undermines the confidentiality and integrity of the affected systems. Although availability impact is minimal, the breach of administrative control can lead to broader system compromise or persistent backdoors. Organizations relying on these CMS/CRM platforms for website or customer relationship management risk data leakage, defacement, or loss of trust from customers and partners. The lack of vendor response and patches increases exposure time, and the public availability of exploit code raises the likelihood of opportunistic attacks. The requirement for high privileges and user interaction somewhat limits the attack scope but does not eliminate risk, especially in environments with multiple administrators or insufficient user training.

Summary

CVE-2026-2965 identifies a cross-site scripting vulnerability in the 07FLYCMS family of products, including 07FLY-CMS and 07FlyCRM, specifically affecting versions 1.2.0 through 1.2.9. The vulnerability resides in an unspecified function within the /admin/SysModule/edit.html file, part of the System Extension Module component. The issue arises when the 'Title' parameter is manipulated, allowing an attacker to inject malicious JavaScript code that executes in the context of an administrative user’s browser session. The attack vector is remote, meaning an attacker can exploit this vulnerability over the network without physical access. However, exploitation requires the attacker to have high privileges (likely administrative access) and user interaction, such as tricking an admin into clicking a crafted link or loading a malicious page. The CVSS 4.0 score of 4.8 reflects a medium severity level, considering the need for high privileges and user interaction, but ease of network access and lack of required authentication bypass. The vendor was contacted early but has not provided any response or patch, and no official fixes are currently available. Public exploit code has been released, increasing the risk of exploitation despite no known active attacks reported. This vulnerability could be leveraged to perform session hijacking, defacement, or unauthorized administrative actions by executing arbitrary scripts in the admin’s browser context.
