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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: 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

Exploitation evidence

Disclosed: evidence found.
CVE published 27 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: evidence found.

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), CVSS vector, 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.

AI-suggested

The vendor indicates that the vulnerability may not be exploitable under normal configurations, as the URL input is restricted to local or trusted domains. Users should avoid modifying the code in ways that could introduce malicious URLs. Monitor vendor communications for any official fixes or updates.

Description

CVE-2026-7086 is a medium-severity path traversal vulnerability in HBAI-Ltd Toonflow-app versions up to 1.1.1. It affects the updateStoryboardUrl function in the Storyboard Export component, allowing remote manipulation of the url argument. The vendor states that the URL is intended to be a local or trusted domain address configured in Docker, and malicious links would only occur if the user modifies the code. The existence of the vulnerability is not fully confirmed, and no official patch or remediation guidance is currently available.

Impact

If exploited, this path traversal vulnerability could allow an attacker to access unintended files or directories on the system where Toonflow-app is running. However, the vendor's statement suggests that the risk is mitigated by design constraints limiting URLs to local or trusted domains unless the user alters the code. There are no confirmed reports of exploitation in the wild. The CVSS 4.0 score of 5.3 reflects a medium severity with network attack vector, low complexity, and no required privileges or user interaction.

Summary

This vulnerability involves a path traversal issue in the updateStoryboardUrl function of the replaceUrl.ts file within the Storyboard Export component of HBAI-Ltd Toonflow-app versions 1.1.0 and 1.1.1. By manipulating the url argument, an attacker could potentially traverse directories. The vendor notes that the interface URL is designed to accept only local or trusted domain addresses configured in Docker, implying that exploitation would require user code modification. The vulnerability is remotely exploitable, and a public exploit exists, but its practical impact remains unclear.
